Wiard 300 Tips and Tricks[modifier]

********************************************************************** ****
Ed Note: this is a collection of tips and tricks for the Wiard 300 series
modules, culled from the Yahoo group archives. They are presented in
random order; the file is updated at the TOP as I discover new material.

Grant: Mixolator as switch:

One request I frequently get is a switch module. The Mixolator will
already behave like the ARP 2600 switch. Just drive the Z input with a 0
or 10 volt signal and use X and Y as your inputs. It just doesn't have the
horrendous thumping of the ARP 2600 version.


A patch from Liquidcolor (Michael Ford)

The Classic VCO is in low mode and acting as the main clock. The noise out
goes to 1/2 of the Envelator (whacking fc1 and qmod on the filter) and
also to the stage select input of the sequantizer. Sequantizer out goes
into 1v on WFC and seq 10v goes out to WFC wave envelope in. Waveform city
is set to bank 2, the input to the non-linear generator is the WGC sine.

The second half of the envelator is being clocked from the freq divided
VCO pulse, and the env out is sent to FC2 on the filter, the mixolator
(vca) #1 and fc2 on the WFC. The sqr out of envelope #2 is sent to gate in
on the WFC.

All in all, there's 27 patch cords in total, but I think that's the main
guts of the thing.


Norman Fay - Sequantizer and Borg 1 complete synth voice.

The other week, I was amazed to discover something which is probably
obvious to a lot of you. Patching the Sequantiser and the dual borg
together to get a basic, but complete sequencer/synth combination! Only a
few patchcords too:

VCLFO1 square out -> Sequantiser Clock
VCLFO1 Saw out -> cutoff mod on *both* filters
VCLFO2 saw or square out -> filter 1 in
filter 1 out -> filter 2 in
filter 2 out -> mixer
sequantiser out -> VCLFO2 1v/oct in
VCLFO1 =3D low range
VCLFO2 =3D high range

Right? VCLFO1's square wave is yr sequencer clock pulse, whilst its
saw wave acts like a preset env. gen for borg filter 1 (set up as VCF to
your taste) and borg filter 2, which you set up as a VCA - IE full mod
depth, LP mode, no resonance. VCLFO 2 acts as yr audio oscillator, with
its pitch controlled by the sequantiser. So much fun & functionality
from 2 modules! Who else's gear can do this?


Grant Richter: Spatial Positioning in multi-chanel systems

The Mixolator module can be used as two simultaneous pan units. These can
feed the left and right channels (for front and rear) in a 4 channel
quadraphonic setup or 5.1 system.

Another Mixolator panner can be used to pan between front and rear.

The combination of the two modules allows quadraphonic panning under
voltage control. Route the Joystick X axis to both Mixolator ZMOD inputs
for left and right positioning front and rear. Route the Joystick Y axis
to ZMOD input on the mixolator panning between the front and rear L-R

The VCA mode in the Borg filter is a 6 dB/octave filter/attenuator tha
mimics the acoustic effect of approaching and receding sound sources
(Thanks to Don Buchla of course). Using a sumer and the triangle wave
function in the Waveform City, you can make a "dome generator" which will
automatically fade in the sound as it approaches the center and fade out
the sound towards the corner joystick positions.

Use some of the "dome" signal to shift the pitch of the oscillator to
mimic doppler shifting (pitch shift up approaching, pitch shift down
receding). You can also use the "dome" signal with the remaining Mixolator
section to control the amount of reverberation, distant sound sources have
more reverberation than nearby sound sources, so crossfade to the
reverberated signal towards the joystick corners.


mrboningen: a compressor patch based on the Borg 2

* 10v p/p sound source to be compressed into a multiple
* multiple out to a) borg2 audio input b) serge/bananalogue vcs input
* vcs out to inverter (i use a serge 3p)
* inverter out to borg2 cv input
* borg out to amp/mixer/speaker


1) the sound source needs to be 10v p/p or it won't "kick" the
compressor enough, so you will need a preamp after the sound source if
it is low level (i first used a bass guitar into the blacet i/o module)

2) the borg2 needs to be set to vca/low pass gate mode, freq. at max
and cv in at max (the inverted envelope pulls DOWN the low pass gate)

3) the vcs is acting as an envelope follower, but the beauty of this
module is that you have seperate control of the attack and release
time (which go from microseconds to minutes!), and they are both
voltage controllable! i set the attack at minimum first, the decay
at maximum, then slowly bring the decay down until i hear the
pumping/breathing/obvious compression characteristic i want, then
slowly increase the attack until i get the right mix of naturalness
and compressed sound. the second beautiful thing is that you can
individually set the attack and decay to be linear, logarithmic or
exponential for a very wide variety of compression characteristics.

interesting variation: turn the borg2 filter repsonse pot from lp to
hp for crazy high pass frequency compression!

i have come across some AMAZING sounds with this patch this evening. i
could get great bass guitar compression and heavenly acid lines. i
will try it on drums at a later stage.

other things to try:
1) use a wiard boogie or another type of low pass gate for a different
2) incorpoate some kind of voltage controlled feedback or feedforward
(would need more mults and mixers)

final note:
i first attempted it with a "normal" linear vca instead of the borg 2,
and the blacet i/o envelope follower instead of the vcs, but it wasn't
nearly as versatile or nice sounding!

Grant: Wogglebug clocking tips

The sample and hold (stepped) output can be clocked by an external clock.

The LFO rate only vaguely relates to the smooth output, so synch would not
mean anything.

The "Disturb Voltage" inputs allow you to trigger a single "Woogle" event,
in time with a keyboard or sequencer (with internal LFO set to longest
rate). The "Woggle Time" control will control the decay time of the event.

The internal LFO rate can be controlled by an external control voltage.

Grant: more Wogglebug tips

The "Woggle CV" output jack can produce audio rate tones when the "Woggle
Time" setting is small or zero.

At small settings of "Woggle Time", the Woggle CV ouput produces a
decaying sinusoid in the audible range. If you lowpass filter it, you can
get the plucked bass tones heard in the original Woggle Bug demo.

At zero settings, the Woggle CV will oscillate strangely and produce harsh
tones which vary with the settings of the other controls.

So the Woggle CV outputs at some settings can be used as the 9th and 10th
audio outputs from the module.

The correspondence between the Model 265 Source of Uncertainty functions
and the identical Woggle Bug functions:

265 SOU label Woggle Bug label

Random Voltage Outputs Smooth CVs
Probable Rate of Change controls LFO Rate controls
Pob. Rate of Change Ext. jack Rate input jack
Stored Random Voltage Outputs Step CVs
Pulse Inputs Step CV Clock inputs
Correlation Controls Clustering controls

The original Model 265 Source of Uncertainty functions are all present and
identical in the Woggle Bug but have been enhanced by the addition of:

Smooth Range
Woggle Range
Woggle Time
Out 1 and 2
Disturb CV 1 and 2
Child Tones 3 and 4
LFO outputs
Smooth Tone outputs
Woggled Tone outputs
Woggled CV outputs

Norman Fay: Favorite Wogglebug patch

There's something weirdly compelling about woggle bug noises. My
favourite patch is to feed the primary output into a borg filter set to
lowpass mode, clock an envelope from the clock out of one of them, set it
for the short transient response, and use it to control the cutoff freq of
the filter. I then take one of the CV outs from the woggle bug, attenuate
it somewhat, and use it to control the envelope decay time. Then finally,
take the smooth CV out of Wbug ch1, and plug it into the rate in of ch2.
And of course, ch2 smooth CV out to CH1 rate in. You have to attenuate
these, as the thing goes completely nuts otherwise. I then record the
result twice, pan them wide and add loads of echo. I could listen to it
for hours.

A good trick with the wogglebug woggled noise, which can be somewhat
overpowering, is to feed it through a high pass filter before low pass
filtering it. Turning the resonance of the HP filter up and then
controlling its cutoff freq with a smooth CV out makes some pretty cool
noises as well.

Plord: clocked Wogglebugs (audio file Wogno 1.mp3 posted to the files

1. Tempo was controlled by using joystick 1 to adjust Wog2-R's rate.
2. All 8 audio outputs of Wog2 sent through a Metalbox Sequential Switch,
which is clocked by the LFO out of Wog2-R, through a Borg 1 filter and
shaped by a Bananalogue VCS.
3. LFO out of Wog2-R to a pulse divider also, /2 division to VCS trigger
4. Joystick 2 controls the rate of Wog2-L, which actually ends up whacking
5 of the 8 tones being switched: Wog2-L main/smooth/woggled outs and both
child tones.
5. The high hat noise is just Wog1-L, clocked from a mix of the /2 pulse
division and some burst gen output, steeply high pass filtered with a Borg
II, no CV control at all.
6. The kick is Wog1-R, clocked off the /4 pulse division of the primary
clock, through the other half of the Borg 1, strongly shaped by another
VCS, resonance up.

Grant: More Sequantizer tips (collected from 3 emails September 2007)

1. A slight voltage offset is normal at the Sequantizer quantizer output
jack. Just plug the 
Sequantizer quantizer output into the VCO 1v/oct. input and use the Sequantizer
transpose input like you would the VCO 1v/oct. input. The allows the Sequantizer to be used as a transpose unit with a Keyboard. Tune the VCO after pluging in the Sequantizer. 2. One of the original ideas behind the Sequantizer is that you can leave it permanently wired to the 1v/oct input of one or more VCOs. The keyboard or other quantized source then plugs into the transpose input of the Sequantizer. This is the same setup used by the ARP 1130(?) sequencer. You can then transpose the keyboard or other source by an octave down, octave up or into any key using a setting on the knobs. For example, leave position one as "normal" with knob set to 0 volts and no patch cords from Gate 1 . For position 2 set the knob to zero and run a patch cord from Gate 2 to the Oct + input. On position 3 set the knob to zero and run a patchcord from Gate 3 to the Oct - input. On position 4 set the knob to transpose a fifth. Then use the Select control knob or jack to change transpositions. Position 2 moves the keyboard or sequence up an octave, position 3 moves the keyboard or sequence down an octave and position 4 transposes the keyboard or sequence up a fifth. The Gate controls can also change patches. You can have one patch controlled by a keyboard or sequencer, and another patch controlled by the same keyboard or sequencer. The Gate outputs can be used to switch which patch goes to the output monitors. Using a crossfader, only a single gate is needed to switch between the two patches. The Gates can also be used for simple changes like switching from a slow attack to a fast one. 3. Using the transpose input of the Sequantizer will also allow you to add portamento to keyboards which don't have it. Like some MIDI/CV converters. Using a keyboard which DOES have portamento and sending it through a quantizer like Bank 15 of the Waveform City or Mini-Wave, you can convert a portamento to a glissando. The sliding control voltage will be quantized along with the key control voltage steps. You may need to use a mixer processor type module to add a 40 millivolt offset to the keyboard voltages so they fall into the "middle" of the 83 millivolts "windows" that the quantizer input has. This should minimize "dithering" when the keyboard voltage is close to a transistion voltage. ******************** Doug Pearson: Explosions 1) On a Wogglebug, set: The clock/LFO all the way up to the maximum rate. Wogglebug main out -> Omni Filter in. 2) On one envelator, set: AD response. Attack very short (or minimum). First +out to AMOD for exponential curve (turn the AMOD knob all the way up). Second +out -> Omni Filter FC1. Set release knob to taste for length of explosion. 3) On the Omni Filter, set: LP mode. Cutoff all the way down. Resonance below self-oscillating, to taste. Adjust FC1 knob to taste for "intensity" of explosion. Using the 12dB out vs. the "main" outs will also give different explosive flavors. 4) Gate the envelope with the button on your joystick controller. ******************** Rayce: Drum loop mangler Try this, take a drum loop (you'll need to preamp it to an appropriate level) and send it into the stage select in on the sequantizer.???Use the output from 10v out on the sequantizer as your audio signal.?? Play around with the various voltage levels of steps 1 through 8.?? Leads to some great chunky results. You can also try putting an audio source into the step in to get bizarre modulation effects (thanks to Grant for this suggestion) ******************** Gino Robair: Wogglebug Solo! Taking Grant's advice I patched Out1 and Out2 to separate channels, panned hard left and right, sending both to a "tape delay" through Aux 1 (in this case, the delay is a Hughes and Kettner Replex pedal, which BTW does a nice job of emulating tape delay). Yup - instant sci-fi soundtrack. For the first hour, I didn't even use a patch cord. The first "patch" setup involved dial settings only. The result was a groovy sort of walking bass sound with high crust on top. It took a bit of fidgeting with the settings below to recreate the original sound, so bear with me if you don't get the same results: LFO Rate: 11:30 Smooth Range: 4:30-ish Woggle Range: 5:00 Woggle Time: 8:30 Clustering: 2:00 Play with the Woggle Time control to find the bass timbre. One side of the Bug was set up this way, while the other was taking the lead. ******************** Dr. Mabuce: Borg Filter self-running percussion Patch cords: 1v/oct1 to mult key fol1 to mult mod1 to tri2 in1 to out2 tri1 to 1v/oct2 saw1 to mod2 sqr1 to in2 out1 to (amplifier) key fol2 to sqr2 saw2 to mult Switches: Osc1 LOW Osc2 LOW Knobs: (positions given as clock hour-hand) FREQ1 9:00 FREQ2 9:00 PEAK1 3:00 PEAK2 3:30 TYPE1 LP (7:00) TYPE2 BP (12:00) MOD1 5:00 MOD2 5:00 OSC1 2:00 OSC2 2:30 ******************** Gino Robair: Borg self-running percussion Semisporadic, quasi-unpredictable percussive sounds For solo Borg module Right Saw -> Left 1v/Oct Right Tri -> Left Key Fol Left Square -> Left In Left Tri -> Right In Left Saw -> Right 1V/Oct Both Mod pots at full CCW Both filter types HP Adjust Freq, Peak, and Osc 1/2 tuning to taste as you play the patch. ******************** Grant: Random Rhythmic Clock The Oct+ and Oct- outputs [Ed note: Inputs? See patch below] from the Sequantizer can be used to modulate the Classic VCO in fixed rythmic intervals of half time and double time. Classic VCO in low range (LFO). Patch the Random output of the Classic VCO to the VCA IN1. Patch the quantized output of the Sequantizer to the 1V/Oct input of the Classic VCO. Reset the Sequntizer and set stage 1 to 0. The Sequantizer is not clocked for this example, we are using just the transpose function. Take the VCA output to either the Oct+ or Oct- input of the Sequantizer. Advance the VCA gain, the VCO will start randomly alternating clock pulse with exact half or double time pulses. The probability of the pulse is set by the VCA gain. The input threshold of the Oct+ and Oct- inputs is around 1.5 volts, so not much gain is needed. Another experiment: Route the random output to a Mixolator X input and route the X and Y outputs the Oct+ and Oct- inputs. Another signal can be used to control the Z input. This will produce a mixture of normal, half and double time pulses as the random voltage is panned between Oct+ and Oct-. The clock pulses can be used to trigger an Envelator controlling the Waveform City VCA. The random voltage can be used to control WaveCity pitch and produce a random sequence with fixed rhythmic intervals. ******************** Grant: Noise Ring as external processor 1. Make sure the "Change" pot is all the way up (LED full on). 2. Input a VCO 10 volt peak to peak triangle or sawtooth wave into "Chance In" jack. 3. Adjust "Chance" control so some LED signal is seen. 4. Monitor main output and play with VCO frequency and "Rate" setting. ******************** Chris: Sequantizer as Envelope Follower drum loop into Borg filter in out to mixer drum loop into Sequantizer step select set the 8 steps on the sequantizer to slowly rise from 0 to 10 v. Quantized output to borg filter mod in (since slide only works off of the quantized output) 10v Seq output to Seq transpose input to transpose the quantized output to the 10v range instead of a 1 oct range. A little bit of slide to get rid of noticeable stepping. ******************** Mike Fisher: Vectrone Classic VCO Sine output to X2 of Mixolator #1 Pulse output to Y of Mixolator #2 Saw output to Y of Mixolator #1 PWM set all the way up; Pulse set at about 12o'clock Sequantizer 10v output (non-quantized) to ENV input of WC Steps 1-8 tuned to trigger different table points on WC Dual Envelator +Out of Envelope 1 to Zmod of Mixolator #1 -Out of Envelope 1 to multiple: to FC1 of Omni Filter, to PWM of Classic VCO SQR out of Envelope 1 to Gate input of WC END out of Envelope 1 to Multiple: to Sequantizer step input, to Gate of Envelope 2 +Out of Envelope 2 to Zmod of Mixolator #2 Attack and Decay of Envelope 1 set about 10o'clock Envelope 1 mode = cycle Attack of Envelope 2 is set to full clockwise position Decay of Envelope 2 is set to approx 8o'clock Envelope 2 mode = AD Waveform City VCA output to X1 of Mixolator 1 Wave knob set to full counter-clockwise position ENV knob set to full clockwise position Attack set to approx 1o'clock Release set to approx 2o'clock Synch set to approx 1o'clock Bank 8 selected Omni Filter 12db output to X1 of Mixolator 2 Coarse knob set to approx 1o'clock FC1 set to approx 3o'clock Mode = AP (All-pass) Q set to approx 1o'clock Add switch set to "On" Dual Mixolator X+ output from Mixolator 1 to IN1 of Omni Filter X- output from Mixolator 2 to WC Synch input X+ output from Mixolator 2 to amplifier, speaker, etc. (this is the main output) X1 of Mixolator 1 is set to approx 12o'clock X2 of Mixolator 1 is set to approx 3o'clock Y of Mixolator 1 is set to approx 10o'clock Z of Mixolator 1 is set to 12o'clock Lin/Log of Mixolator 1 is set full counterclockwise (Linear mode) X1 of Mixolator 2 is set to approx 1o'clock Y of Mixolator 2 is set to approx 10o'clock Z of Mixolator 2 is set to 12o'clock Lin/Log of Mixolator 2 is set full counterclockwise (Linear mode) Notes: If voltage control of pitch is desired, 1v/Oct goes to Classic VCO and Waveform City. Bank 8 is used for this example but any bank will produce interesting results. The speed of the vectoring (such that it is) is set by A and D knobs of Envelope 1. Sequantizer is "tuned" manually so as to trigger different waveforms in the WC. Oscillators were set to "high" pitch mode for the example, but would probably also produce interesting results in "low" mode. ******************** wiardmodular@?: Omni Filter as VC Slew Discovered a neat trick today with the omni filter. Run a cv into it, set it to low pass. Run a voltage into the FC2 and adjust to invert it so you can lower the frequency of the filter way below minimum. This will give you noticeable slew times. Otherwise the frequency of the filter is too high to have a noticeable slew. Run the output to the cv in on something like your oscillator. The filter will slew between changes on the cv in. This allows you to have a voltage controlled Slew in the wiard 300 system. You can also do interesting cv filtering on lfos etc with this patch. ******************** Gary Chang and Grant: Other Slew sources Gary writes (but see below): I often use the VCA circuit on the Waveform City as slews - there is a jumper on the pc board that switches the vca to a slew, allowing the output to track the voltage at the gate input, with the attack and decay controls adjusting the positive and negative sides of the slew... Grant replies; Of course you meant the little envelope generator inside the Classic VCO and not the VCA. The Classic VCO has three seperate modules in the one box, VCO, VCA and AR envelope/envelope follower. You can also feed audio into the "Gate" input and the envelope output will follow the positive peaks at the rate set by the Attack and Release knobs. ******************** Stefan Bonnet: Filter tricks Running two borgs in parallel produces astonishing stereo images, from natural spacializing to sweet resonant phasing effect when animated... It's also possible to create some really beautiful and precise harmonic/formant structures when mixing the boogie's and the two borg's outputs in parallel and setting one of them to track the keyboard. (btw my borgs sound a bit different, the last one I received distorts more easily, but with a more crunchy sound, and allows to highlight specific harmonics more precisely, with an even more "woody" sound than the other (!)) I've also been able to find a very convincing cello sound with the boogie as a control source : use the boogie to shape white noise (find the right mix of its four outputs), control its frequency with an eg (I used the very nice bananalogue vcs for this, too sad it's output isn't normalised to the "both" input...), and crank up its resonance. Then patch the mixer's output to the control input of a borg, the vactrols will do the rest ! (adjusting the boogie's parameters allows for a lot of funny effects, like when the borg's vactrols won't be able to track anymore, but there's a sweet spot where the attack is a cello one !) (the other borg is used as tone/body shaper, and the sound source is the sine output of a fixed frequency vco, fm'd and sync'd by a tracking vco/miniwave). As for the noise ring, it conducts bird singing very convincingly, especially when the miniwave is used as a transfer function device in order to get different probabilities' distribution...But I like it mostly as control source modifier/exciter and tone source (in which case I patch a note-on pulse to the ext change input, to get that ever phased-out sound without clicks)...(It woud be great to have a jumper on its back, allowing to use the clock output as a clock input (?)) ******************** Grant (via Gary): WFC as a Voltmeter The other day, Grant told me of an very useful patch with a Waveform City that helped me to troubleshoot a patch involving ghost errant triggering when the last gate out of a Sequantizer was used to step a second Sequantizer. Setting the Waveform City to Bank 0 and Wave 0, and turning the ENV to maximum, it will act as a voltmeter, measuring the voltage from the WAVE ENV input. From this, I could see that the gate out was performing properly. Grant surmised that ghost triggering must be tiny glitches that were triggering the very sensitive gate inputs of the Wiard. By passing the trigger through a vca found on the oscillator (which is actually a bidirectional slew), the problem was solved. I now use this "Voltmeter" patch all the time. ******************** Grant: West Coast techniques and tips 1. VCO(sine) - VCA - LINFMVCO(sine) - Borg in lowpass gate mode (VCA) You use the first VCA to dynamically control the depth of linear FM. Envelopes are routed to the FM depth VCA and to the Borg tone shaper. The use of sine waves produces "nice" sounding FM along with the soft Borg envelope. With the first VCO set to about 7 Hz and the linear FM control of the second VCO barely open, you have dynamic and natural sounding vibrato. 2. VCO(sine) - LINFMVCO(sine) - VCA - Mini-wave(+/- 5v) - Borg in lowpass gate mode (VCA) This is a fixed depth FM patch going to a dynamic depth wave multiplier. Envelopes are routed to the first VCA and to the Borg. The VCA before the Mini-Wave needs to have controls to set initial volume and control the amount of envelope (like an ARP 2600 VCA has). You want to adjust the VCA so it is about 20% on with no envelope. Then adjust the amount of envelope sweep to your taste. You can play with any bank or wave in the Mini-wave but Bank 13 is designed just for this use. 3. Banks 0 to 7 of the "Socket Rocket" chip are designed to process audio input. In this case the VCA is set 100% on. Bank 6 "Bit Descimation" can really make a drum track gnarly when set to 4 bits or less. 4. Since all the output are protected by 1K resistors, you can use simple multiples to mix module outputs together. For example, to place Borg 1 ouptus in parallel, just run the same signal to both inputs and connect both ouputs to the multiple at the bottom of the patch bay. Since every module input and output is fault protected, this means you can connect the modules without fear to any other type of module. It should be impossible for the Wiard to do any damage to any other kind of module, and likewise the other modules can not damage the Wiard modules. So, it is safe to patch the Wiard 300 or 1200 modules to modules from other manufacturers. 5. The Korg MS-20 added some diodes to the feedback amp used to give resonance. The effect is to have the resonance vary with the amplitude of the INPUT signal. So the resonance is self limiting, and you can max it out and it will "squelch" with input amplitude. This feature is controlled by the red option jumper on the back of the Borg 2 modules. With the jumper in place, you will probabaly get better results with the filter AFTER the VCA (assuming a subtractive patch). This way the little circuit will crank the resonance up and down for you automagically, kind of like gain riding. With the jumper moved to a single pin, it will offer all the time "rip-your-head-off" resonance like the Borg 1. Because the Borg 2 IS a Borg 1 with much faster Vactrols and the one added tweak. ******************** Grant on using the Boogie as a Low Pass Gate It's a mode unique to photo-electric filters. Any other transconductor (transistor, diode, OTA) can not run to zero control current without making bad things happen to the DC bias and producing 15 volt thumps. But photo-electric filters go completely off (0 Hz). This allows you to use the filter as a combined VCF and VCA. In the West Coast model, the complex timbres are generated before the filter via complex oscillators, non-linear waveshapers, FM or additive synthesis. The "gate" is then used for final amplitude and spectral shaping. The Boogie supports both modes, either straight subtractive with a following VCA, like the East Coast instruments, or gating and spectral shaping without a following VCA, like the West Coast instruments. The main frequency control covers 20 octaves, 0 to 20 Hz, which is 10 octaves, and 20 Hz to 20 kHz, which is another 10 octaves. To "gate" with the Boogie, set initial frequency to zero and control range to max. Resonance is set to zero. A 10 volt signal into "Control In" will then sweep the filter from 0 Hz to 20 kHz. The 6 dB output is approx. equivalent to the Buchla 292 "combo" mode, and the 12 dB output is approx. equivalent to the 292 "filter" mode. But the Hamamatsu opto-couplers decay in 20 ms., rather than the 200 ms. decay of the VTL5C3/2 used in the Buchla 292C. [And, on the use of the two Boogie jumpers] One jumper is for the 24 dB output and the other for the 12 dB output. Move both to top position if your mixing with the Blacet Mixer Processor. Leave both at bottom position if you are mixing with the Blacet Quad VCA. ******************** Matthew Ritenburg: Sequantizer as a graphic VCO 1. Noise ring out -> 1v/oct VCO in. 2. VCO set to audio range in 9:00 position 3. Triangle out of VCO into stage select of sequantizer 4. Sequantizer stage select set to to 12:00 5. Sequantizer 10v output to mixer. If you have a scope you can change the speed of the VCO and change the voltage stage settings of the sequantizer to view the changes in the wave form. Using the sine, saw, or pulse from the VCO produce different timbrex. I prefer the triangle. ******************** Olivier: JAG Monster patch With one JAG, a Joystick, two modulation-mixers(in my case Blacet Mixer-Processors), 2 LFO's 2 Envelopes into that, 10 Outputs of the JAG modulate 10 CV's. The JAG controls a Vector-Engine as Vector-Synthesis is very easy to control, as I am not a fan, if the JAG controls the Pitch-CV. 2 VCO's/Mini-Wave/Frequency-Divider and one half of the superb Cynthia Saw Animator ar going into 4VCAs), everything is run by 2 VCO's. The output of the 4 VCA's are going into a Mixer, then 2 parallel/serial Filters and two vca's. That is also kind of CS-30 alike (2Filters/2VCA's). I tried it with my Wiard/Blacet-Rack: It sounds incredible. The JAG brings the modules to life: With the Joystick you tell the main Direction, every millimeter changes the whole character, so I work with a stereo-delay behind everything. The two modulations-mixers (one JAG) a bringing incredible movement into everything >>(Filters, VCA's, ..), subtle or gigantic. What I like the most is that it is a extremely fast way to program new sounds, and they are still vanilla enough to be useful. Of course the Vector-VCA's are 8, 6,4,2. The rest (Cutoffs, Speed of LFO's, one controlling the first output-VCA, balance/Pan of the two parallel filters...) will be controlled of the other JAG-Outputs. At the moment, I am testing which one to which output is best. The Egde and the Dome-Outputs of the JAG are perfect for some CV's. It can get pretty wild in a Vector- Patch, if the Edge-Out controls the Q of the main filters, but I haven't decided yet which output controls what in the end (or if I build in switches) ******************** Grant: Ring Modulation in the Wiard (two posts, "Balanced Modulation" and "Mixolator as Ring Modulator") Envelator: 1. Env1 Out + is normalled to Mix module Mix 1 input. 2. Patch Env1 O- (Out minus) to mix module Mix 2 input 3. Set Env1 to "Cycle" with A and D set short 4. Listen to the Mix module output 5. As you advance the Mix control, the signal will null when the two out of phase versions have equal amplitude and cancel. 6. Now take an audio VCO sine ouput into the MixMod input and advance the MixMod control. You will hear the "Klang" (sum and difference) tones fade up. Mixolator version one: The same technique should work with the Mixolators using the X+ and X- outputs of one to feed the X and Y inputs of the second. Modulation signal to X1 input of the first with Z at max. Feed the carrier signal to ZMOD of the second, and null the modulation signal with the second Z control. This is essentialy what the Ring switch does on the Mixolator, but this technique is more adjustable with better linearity. Mixolator version 2: The technique goes like this: Monitor the X+ output 1. Set X1 control fully on 2. Switch VCA/Ring switch to "Ring" 3. Patch an audio sine oscillator (carrier) to the X1 input 4. Adjust the Z control for the best null of the carrier signal (somewhere around the 1 o'clock position) 5. Patch another sine wave signal to the ZMOD input. At this point you should be hearing two sine tones which are the sum and difference frequencies between the two sine wave oscillators. Sweep the oscillator frequencies as an experiment. Any audio signal can be used instead of sine waves, but they are best for demonstrating the sound. ******************** Dr. Mabuce: Sequantizer tips The permutation range from the CV controlled 'select' is a powerful stuff. When the Sequantizer is clocked at audio speeds is becomes a CV waveform modulator. Hitting the reset with a pulsewave tuned to NEARLY the same frequency creates a wicked 'ultra-hard-sync'. At slower speeds this can be used a varying complex envelope. A lot of the features look un-glamorous but are very musical. I use the octave shift all the time. The step-selectable glide is another feature that breathes life into sequences without having to patch-in 4 other modules. One feature that I ho-hummed at, turned out to be something I use ALL the time. With the sequencer sitting still, (unclocked) you can use the select knob to step & stop through each step. I know it doesn't sound like anything of monumental consequence but it makes creating & testing (creating-testing, creating-testing, & on & on) a sequence SO CONVENIENT. It just seems to have been designed by someone who had actually programmed a LOT of sequeneces on an analog himself ******************** Grant: Envelator Mix module logic and quadrature mode OK, one of the original functions of the SQR output on the Envelator was to act as mono-stable for making a gated ADSR envelope. That is if you have two Envelator modules, you can set up one as an ADSR and another as a monstable, this will give you a fixed gate time and allow you to "loop" an ADSR with the end pulse. The polarity is wrong for using it in quadrature mode, SQR goes high and stays high as long as the Envelator is in the Attack portion of the envelope. For quadrature, you need the inverse. You can use the cossfader on the bottom as a logic inverter to get the correct polarity. Here is how: 1. Put a dummy plug into the Mix2 input (disconnect Env 2 output) 2. Route a +10 volt signal to the Mix 1 input (a joystick all the way up will work) 3. Route the Env 1 SQR signal to the Mix Mod input (mixture modulation) 4. Set the MixMod control to max and Mix control to min 5. Route the Mix output to the gate input of Env 2 Now Env 2 will start it's attack phase as soon as Env 1 completes it's attack phase, also called quadrature mode. Route Env 2 END pulse to Env 1 GATE input to make a quadrature LFO. How does it work? When MixMod is at zero volts, Mix1 is routed to the Mix ouput, and it is at +10 volts. When MixMod is at +10 volts it is routing Mix2 to the Mix output, which is at zero volts - hence an inverter. If you think about it, the Mix section on the Envelator can be used for logic functions, AND would be MixMod at +10 AND Mix2 at +10, otherwise the output is zero. The input thresholds of gate inputs on the system are set to +1.5 volts so you can interface to +5 volts systems like Kenton and Roland rhythm boxes. So with the MIX control set to the center, with +10 volts at Mix1 OR Mix2, +5 volts will be output from the MIX output. Because the gate threshold is at +1.5 volts, it will behave like an OR gate. ******************** Grant: PWM of Sequantizer Gates with Mix module The gate 1-8 outputs of the Sequantizer module are diode isolated so they may be "wire or'ed" at a multiple. However the gate signal does not go low with the clock pulse, this make it difficult to use two successive stages as a trigger for an envelope. By using the AND logic mode of the Envelator Mix module, you can PWM the gates and get a correct trigger pattern for rhythmic trigger patterns from the gates. Here's how: 1. Set the Envelator MixMod control to maximum and Mix to minimum 2. Put a dummy plug in "Mix1", disconnecting Env1 (a dummy plug is just a patch cord with only one end connected, this is used to break a normalization on a module). 3. Make a pattern of some of Sequantizer "Gates 1-8" at a multiple, then route a patchcord from the multiple to "Mix2" input. 4. Set the Classic VCO to low speed and route the Pulse signal to Sequantizer "Step" input and the Mix module "MixMod" input. 5. Route the Mix output to a Envelator or other envelope generator "Gate" input. What happens: Since the gates signals are now ANDed with the clock, they will only go high only for the pulse width of the clock signal. This will correctly trigger the envelope on consecutive stages. By patching the Classic VCO "Rand" output to the PWM input, you can have random articulation (varying gate times) of the rhythm pattern. ******************** SDCurtin (?): Envelator chaotic functions One of my favorites is to use the envelator as a voltage-controlled divider. If you feed a 5v audio rate square or ramp wave, then change the rise time, you get subharmonics. Grant also mentions this capability in one of the online Wiard manuals. But wait, there's more! Feed the output of this into the classic VCO or other syncing oscillator, you then get harmonics. The combination of this is very usable just intonation. For instance, for a frequency ratio of 5/8, you dial up the 5th harmonic and the 8th subharmonic. ******************** Grant: Linear Feedback with Wiard-VCO or Waveform-City In order to have dynamic depth FM without shifting the basic pitch of the oscillator, an AC coupled linear FM input is required. This is exactly the design of the LIN input on the Classic VCO. One of the purposes of the VCA in the module is to provide dynamic depth control for this FM input. Used with an external oscillator, the FM modulation can be varied dynamically with the minimum amount of pitch shift. The reason that this does not work with an internal waveform is because it is synchronized. As you feed back the sawtooth signal into the FM input, you are telling to oscillator to go faster the further along the curve you are. This is what produces the bending of the line. (The same technique is used to bend the linear Envelator segments into exponential shapes by feeding back to the AMOD or DMOD inputs.) Mathematicly, this synchronized "speed up" signal ends up like a constant offset changing the period (pitch) of the waveform, and is not blocked by the AC coupling. This is why the pitch changes when the feedback depth is varied. You can partially compensate for this by taking a negative going version of the feedback depth modulation signal, and using it to push the pitch back down. Try this patch: Classic VCO - Sawtooth to VCA IN1, VCA out to LIN (FM) input. Envelator -OUT+ to VCA ENV input, OUT- to Classic VCO FC1 input. Adjust depth of FC1 control to compensate for pitch shift. This may or may not produce acceptable pitch compensation for a keyboard type patch. It may also produce interesting swept sounds if the control positions are exaggerated. ******************** Norman Fay Live Setup: 4 voices 1 - Step-up sequencer: Binary Zone ->Wave City1 VCO ->freq divider -> omni filter ->Quad mix/VCA 2 Bass sequencer: Sequantizer -> Wave City2 VCO ->Final Filtre ->Wave CityVCA ->Quad mix/VCA 3 Mighty Bass Drone: Blacet VCO & Borg Filter VCO2 -> Boogie filter Boogie filter cutoff controlled by Borg VCO1 and W/bug smooth CV 4 space chatter: W/bug out ->Borg 1 in (HP, high res)->borg 2 in (LP)->quad VCA/mix Borg 1 cutoff controlled by w/bug woggle CV out, Borg 2 cutoff controlled by EG1 out. Decay on EG1 controlled by w/bug step CV out. ******************** Norman Fay: Another Live Setup (Mixolator detail) 1/the noise ring fed one of the waveform city wave shapers, which was set to one of the quantising wavetables. This then ran into the omni filter, and this went into the x1 input of the LH mixolator. The omni filter cutoff was controlled by the ar envelope of the waveform city. The idea was to have a kind of randomly generated sequence. 2/the other waveform city ran into a blacet frequency divider, which ran into a borg filter, then into the x2 input of the lh mixolator. The idea here was to have a manually controlled drone, where I could control the timber of the drone via the borg, and add interesting subharmonics via the level controls on the frequency divider. 3/a woggle bug output via a borg to the y input of the lh mixolator. the clock out of the wogglebug triggered a blacet EG1, which controlled the cutoff of the borg. I took the step cv out of the other half of the wogglebug, and stuck it into the decay cv of the EG1. I was kind of hoping for the transmission from outer space thing the wogglebug can do. LH mixolator x+ out went to x in of RH mixolator. LH mixolator x- out went to a blacet time machine. The output from the time machine went to the y input of the RH mixolator, using the joystick I could control the balance between the wogglebug and the 2 more, er, "tonal" elements on the horizontal axis, and the blend between dry sound and delay on the vertical. ******************** Doug Pearson: Live rig patches I've found that the best 6-piece system for me is the basic one, with sequantizer replaced by borg ... and maybe classic vco replaced by wogglebug if I'm in a weirder mood). One (cliched, but it works) control setup I commonly use: R joystick X Waveform City Fc R joystick Y Omni Filter Fc L joystick X Borg LFO Fc L joystick Y Waveform City VCA CV (amount of LFO modulation to Waveform City Fc) One button wired to EG to VCA and/or VCF (so that either the button or R joystick Y can turn the sound on) Maybe the other button wired to EG to Waveform city wave CV...or elsewhere There's an old digitech RDS delay in the rack box I keep the Wiard in, so I have 1/4"<->1/8" cords plugged into it ... it's usually inserted between filter & mixolator. It's also nice to get a feed (if the amp has an fx loop or line out jack) from the guitarist to process that signal (as with Eno/Manzanera on "Gun" or Del Dettmar filtering Dave Brock on "Space Is Deep"). ******************** Dr. Mabuce: Live Rig and patches My latest obsession is doing the CV control of the whole shebang with a JAG and a Joystick. I patch 4 independent voices - all doing radically different things and put 4 VCA's controlled by points 2 4 6 8 on the JAG, last in the signal chain before i sum them to a single output (with a DI to the stagebox) I assigned the other JAG vectors to various other CV paths like ?increase/decrease chance of octave change' or the mode parameter of the sequantizer (a favorite) or more mundane parameters like Borg cutoff F, sample/hold clock speed. I map Edge to pitch CVs for final manual control of all the VCO pitches - I usually give myself a range of a fifth above and below base pitch. The SNO has on-board MIDI-to-CV and MIDI-beat-clock-to-trigger pulses. So I merge a simple MIDI beat clock feed from our drummers clavia ddrum rig to give him control of the sequantizer clock tempo and other tempo-dependent parameters like LFO speeds and envelope triggers. And I use a MIDI pedal keyboard (like a Taurus,and shared physically with our keyboard player), to control pitch CV's via MIDI. She and i split the pitch-control duties depending on the complexity of our parts during the set. ******************** Grant: JAG introductory notes The JAG is a new module design that takes any two input voltages, and makes all the inversions and combinations available simultaneously. It is a two input, ten output folder/twister/combiner. You could also look at it as a kind of Cartesian barberpole generator. They original X and Y inputs are passed through to be used in the patch. Or a second unit with X and Y switched will give another 10 functions shifted by 90 degrees. The output fuctions can also be used an inputs to another JAG for really bizarre shapes. The most obvious application is for panning. The corner functions supply control for the 4 VCAs, and the edge function supplies a correction function for equal power panning. The function is used to boost the output in the middle of the pan, eliminating the power drop in the middle. Run the other way, it is useful for Joystick controlled MIXING. For example, running 4 waveforms from a VCO to 4 VCAs allows you to mix them with a Joystick. This is also called "Vector Synthesis" since the Joystick voltages can be replaced with envelope voltages or LFOs. The 4 waveforms could also be the output of 4 different effects units or other waveform processors. Another example is to use two envelopes as the inputs. This will produce 10 envelope "variations" that can be routed to 10 different parameters in a patch (PWM, filter sweep, filter Q, crossfading between two filters, waveshape control, envelopes times etc.). If a Joystick is used, it gives you control of patch timbre in real time. Fun when you are running a sequence and dynamically morphing timbres. For example, the four corner or side functions can control all 4 attack, decay, sustain and release times at once. So the single Joystick can give you all possible envelope shapes mapped across the Joystick plane. ******************** Grant?s note on ?The Wiard Layers? Here is an ouline of how I envisioned the discovery of the 300 series modules. This is in relation to the discussion about modifications. 1. Exploring what the module can do in the sense of a traditional modules. That is, exploring the tone colors of the VCO, Envelator as ADSR and so on. 2. Exploring the axilliary modules within the enclosure. Discovering the VCA and envelope/slew in the classic VCO for example. Using them to do things like dynamic depth linear FM or as an additional attenuator for FC. 3. Discovering the strange modes of operation. Like using the Envelators at audio rates for chaos generation, using the Mixolators as balanced modulators, switching ranges to "Low" and exploring the outer edges of the functions. 4. Simple modifications. The multiple jacks labeled A,B,C,D at the bottom of the modules are only connected by solder bridges. This can be easily removed and the jacks connected to internal points on the modules. For example adding the external bank select and the second VCA input on the Wavefrom City. 5. Complex modifications. Every stage in each modules has a test point which can be used to patch out the module. Each module could support 50 jacks, but you would need the intelligence of a Martian to use them. None the less, the idea of "circuit bending" the modules themselves has been built into the design. 6. Normalizing into virtual instruments. After you have discovered what you like about the modules, you can permanently normalize them using the exposed points on the jack boards. 7. The one the customers find that I did not think of... ******************** Grant: Envelator tips and tricks Since there are two envelators I will use 1 on the left and 2 on the right. It doesn't matter though. 1. Shorting OUT+ of 1 to OUT+ of 2 in cycle mode will make the Envelators alternate. This is the same as patching END1 to GATE2 and END2 to GATE1. 2. Shorting SQR1 to SQR2 will produce hard synch in cycle mode. You can also run an external oscillator into the SQR output to produce hard synch. 3. Use the mixer at the bottom as a logic inverter to get quadrature operation like the Buchla. Patch SQR1 to MIXMOD input and set the MIXMOD control to max. Set MIX to minimum. Put a dummy plug in MIX2. Route 10 volts from a Joystick set to maximum to MIX1. The MIX output is now the inverted version of SQR1. If you route that to GATE2, the second envelator will start it's attack exactly when the first envelator finishes it's attack and enters decay phase. 4. For chaotic function generation, patch AMOD1 and DMOD1 to OUT+2 and/or OUT-2. The patch AMOD2 and DMOD2 to the outputs of envelator 1. Put both in cycle mode. This is the classic "tail chasing" oscillators that was used in the original demonstration of chaotic systems. Listen at the MIX ouput. You will have to set both attack and decay controls to less than maximum. Try various settings of A,D,AMOD and DMOD for different effects. ******************** Dr. Mabuce: Envelator Chaos patch: DMOD1 to OUT-2, SQR1 to GATE2, GATE1 to SQR2, OUT+1 to MIX1, OUT-1 to MIXMOD, DMOD2 to MIX OUT, OUT+2 to MIX2, OUT+2 to audio input of amplifier path knobs: (given as approximate clock hour-hand positions- it's the best I can do with text) attack1 - 11:00 attack2 - 1:00 decay2 - 11:00 Amod1-doesn't matter Amod2 - doesn't matter Mix - 5:00 (maximum) ------------------------ Decay1, Dmod1, MixMod & Dmod2 become interactive, You just play with them until the sound makes you happy (or disturbed) switches: 1-AD 2-cycle ******************** Sebastian Kuehnl : "Creating a three-dimensional timbre matrix" Ingredients: 1 Waveform City, 1 Sequantizer, 1 Omni Filter, 1 Mixolator, 1 Joystick (MAY be replaced by any two DC offset sources, such as modwheels, but shame on you). If I correctly understand the functionality of the modules, this patch will use the Sequantizer as an NLT board, and the Omni Filter as a processor/ generator changeling. Instructions: 0. Patch the the same pitch control to the 1v/oct inputs of the OMNI and the WC VCO. 1. Patch the sine wave output from the WC to the multiple, and from there, 2. patch one sine wave to the WC's VCA, 3. patch the VCA output to the WC's NLT, 4. select an NLT function that folds a sine wave in the classic Buchla/ Serge way, 5. patch another sine wave to the SEQ stage select input, 6. use the square wave from the WC to trigger the SEQ, 7. patch the EG from the WC to both the VCA CV input and the SEQ's transpose input, 8. set the EG to slope times slow enough to make the foldover-induced timbral sweep in the WC NLT plentifully relishable (=looong! ;-), 9. set the SEQ's stages to arbitrary, preferrably large intervals (at least two stages should be fully down/ up), 10. patch the SEQ 10v output and the NLT ouput to the OMNI and mix them to equal volumes. Interruption: at this point, there should be two rich sounding waves in the filter input, each of which hardly resembles classic analog sounds, and is further dynamically varied by the EG. Since one phase on the SEQ will take eight times longer to cycle than one phase in the WC NLT, the two waves are three octaves apart. (By using the SEQ reset input, a two octave spread can be had, but at the cost of four SEQ stages, which will make the sound only half as detailed.) The less linear and the "wilder" the selected WC NLT function, the larger the perceived timbral and pitch difference between the two SEQ and NLT outputs. By twiddling the SEQ stages and searching for similar and relatively linear functions on the WC, the sounds can be made approximate each other. In the most extreme case, a PPG Wave like sound can be achieved. Also, by applying some lag (glide) on the SEQ, its sound can be smoothened. (I don't know if the lag is linear or exponential? The latter would be better here since the smoothening would be independent from pitch.) Now if the two sounds ARE spread widely, the OMNI voltage controlled mode morphing can be used to discriminate between them like this: 11. Set the OMNI frequency to the middle between the frequencies of the two input sounds; temporarily introducing self oscillation will help to adjust the relations precisely, but it will be best to use your ears rather than sticking to mathematical ratio. 12. Set mode to bandpass, 13. attenuate the X output of the joystick to 3/4 the full range (7.5 volts) with one of the MIXOLATOR sections, 14. patch the attenuated X voltage to the OMNI mode morph input. Using the joystick over the entire X axis will now sweep between lowpass and hipass, and the 24db/oct cutoff should now clearly attenuate either of the two inputs in either mode. Now a third dimension (= another direction to "morph into") is introduced: 15. Patch the third sine wave from the WC multiple to the second MIX section in VCA mode, 16. patch the joystick's Y-axis to the multiple on the OMNI, and from there, 17. use one Y voltage to control attenuation of the sine wave on MIX 2, 16. use a second Y voltage to control the Q amount on the OMNI (with full index); 17. now patch the output from MIX 2 to the OMNI's linear FM input. As you move up the Y axis, the filter will start to self oscillate, the filtered signal will cease to pass - the filtered NLT timbre morphs into a two operator FM timbre. Optionally, if you want to have the VCF frequency envelope swept in the two "filter the two NLT sounds" modes: 23. attenuate the envelope with a VCA whose attenuation is controlled by the inverse of the control source that you previously applied to the FM index and the Q. This is just to make sure the FM sound will produce keyboard- compatible pitches, but if that's not desired and the results should instead be less foreseeable, it can be left out of course. I didn't include gating, the sound at this point is just an endless drone - mostly of interest for examination of the morphing sweeps. But there are more reasons to add the Classic VCO to the patch than just making use of its VCA and EG for gating the drone sound; actually The patch is just a basic configuration to start from, and points to begin modifying could be: Using the Classic VCO for the SEQ NLT sound; with now freely definable octave spread/ slight detune/ individual vibrato settings/ etc etc, this will allow really PPG-like sounds.... Controlling SEQ trigger and select inputs from different VCOs, which Gary Chang described as a method to generate "ultra hard synch" like sounds.... ERRATA on the above: I made a big mistake in my "3D timbre matrix" patch: the sine wave that selects the stages on the SEQ must of course be eight times slower than the pulse (or other) wave that triggers it, so it can't be from the same VCO. (...Unless you use another WC, or a Miniwave, deploying the "binary rate multiplier bank"; Or unless you use an Envelator as a rate divider; the sloped output should make for a nice SEQ select input as well.) So to make the patch work like intended, skip to the end of my previous message, where I mentioned the alternative of adding the Classic VCO to the patch for variation. The original "3D patch" WILL work with this slight modification: - Use the Classic VCO sine wave as the SEQ select input; - Synch the WC VCO to the Classic VCO (a soft synch setting should suffice, we don't want to the sine wave on the WC VCO to distort) and make it three octaves higher. (If the synch is left out and there is some detuning, the two waves controlling the SEQ will interfere and the SEQ output, but then you may like that?) Another, smaller mistake in my patch was the use of an EG for the SEQ transpose input. Just leave it away. It will actually just introduce DC offset, not cause a function remapping like the WC's NLT board does.
