cordes sympathiques

http://www.synthe-modulaire.com/t3363-mi-rings-cordes-sympathiques

Comment sont organisées les combinaisons de cordes sympathiques ? Peut-on imaginer un mode 'teleharmonic' sur Rings ?

Ce sont différentes combinaisons de quintes justes et d'octaves (donc rapports de fréquence 1.5, 2, 3, 4, 6...), avec un portamento entre pour avoir des résultats dissonants.

Pour avoir une table d'accords plus "occidentaux", laisser le doigt appuyé longtemps sur le bouton de droite (il clignotte lorsque la deuxième table d'accords est active). On a alors le "power chord" au milieu, les accords majeurs à droite, mineurs à gauche.

Alternate modes

Threesome

Hold the polyphony button for a few seconds. This enables a 3 voice polyphonic mode in which the notes bounce between the ODD / EVEN outputs according to an 8-step rhythmic pattern (O E E O E E O E).

2-op FM aka "It's still Bessel functions!"

Long press on the model selection button while modal synthesis is active (green).

STRUCTURE = frequency ratio. BRIGHTNESS = FM index. DAMPING = FM index and amplitude decay. POSITION = Feedback path (no feedback at 12 o'clock). IN goes into an envelope follower changing FM index and output amplitude.

"Western chords"

Long press on the model selection button when sympathetic strings model is active (orange).

The sympathetic strings are no longer tuned to perfect fifths or octaves, but instead, to chords.

STRUCTURE = chord.

"Karplusverb"

Long press on the model selection button when non-linear string model is active (red).

Adds a reverb, the absorption and decay of which follow those of the string.

Easter Egg

"Disastrous peace"

The actual Easter egg. Adjust the knobs:

Rings Easter egg

First, set the knobs as follows:
Frequency: fully ccw
Structure: fully cw
Brightness: fully ccw
Damping: centre
Position: fully cw

Attenuator knobs as per the image:
Brightness: fully ccw
Frequency: fully cw
Damping: fully ccw
Structure: fully cw
Position: fully ccw

Once knobs are positioned, a long press on the polyphony button (the mode button seemingly works as well?) initiates an orange/red flashing pattern on both the polyphony and mode leds.

This is an Organ/String machine synth, loosely based on the Roland RS-09. Up to 12 notes and 6 oscillators per note tuned one octave apart ("organ" = filtered square or "string" = sawtooth).

Polyphony button = chord size. From 10-note fat chords which cannot overlap because they eat all the polyphony voices... to 3-note chords which can overlap with the previous ones when they are retriggered. In other words, that's the maximum number of successive chords which can overlap - 1, 2 or 4.

Model selection button = FX. Long press to get a variation on the FX. Green = formant filter (less abrasive variant). Yellow = Rolandish chorus (Solinaish ensemble). Red = Caveman reverb (shinier variant).

FREQUENCY = root note.
STRUCTURE = chord type.
BRIGHTNESS = scans through various registrations (combinations of gains for the 6 oscillators) sorted by brightness.
DAMPING = decay time, then attack time. Drones continuously when turned fully clockwise.
POSITION = FX amount.

The STRUM input triggers the envelope and allocates a new group of voices for the chord - and the previously played chord can still be heard if the "polyphony" setting is set to 2 or 4.

The V/OCT input controls the root note. If nothing is patched in the STRUM input, sudden changes on this input will also trigger the envelope / voice allocation.

IN : It goes into the FX (formant filter, chorus or reverb) - the amount of which is controlled by POSITION.

Olivier's notes

Also, it seems to me that because the modules can be used on their own (you can plug something in Clouds and get a signal on the out without any other module, and you can plug a trigger or V/O signal into Rings and get something on the outs), people tend to treat them as black boxes and don't experiment much with them.

Here's 10 things you can do with Rings that no video has shown so far:

• Create your own excitation signals with "long" signal chains like sample player -> VCA -> filter ; or envelope -> VCF -> delay.
• Feed back Rings' output into its FM input.
• Use simple noise as the excitation signal, and then shape the sound with an ADSR and VCA after Rings' output.
• Stack the sound of Rings on top of a more classic FM or subtractive tone.
• Use Rings' output to FM an analog sine or triangle VCO, then apply an envelope on this VCO coming from an envelope follower receiving Rings' output.
• Post-process Rings' output with a wavefolder.
• Use a crossfader to crossfade an external excitation signal (noise for example) with Rings' own output (feedback patch).
• Use a random source on all of its CV inputs to get drastic changes of timbre at each note.
• In non-linear string mode, send a negative CV to the V/O input and set frequency to the minimum to get a very low fundamental frequency - you get rhythmic-rate delay, and can use the module as a weird low-fi delay/reverb.
• Send a sawtooth or narrow pulse VCO into Rings' input, and use the same V/O sequence for both Rings and the VCO.

unsorted

polyphony :

1 = fat chord (8 notes), but when a new chord starts (trigger on STRUM or a change on V/Oct), it cuts the previous chord.

2 = slimmer chord (6 notes), but when a new chord starts, the old chord can still be heard.

4 = even slimmer chord (3 notes), allowing several consecutive chords to overlap (very obvious with DAMPING near 3 o’clock).

Brightness scans through various arrangement of the drawbars, sorted by brightness. The available registers are 8’ “dark square”, 4’ “bright square”, 2’ “bright square”, 8’ saw, 4’ saw, 2’ saw. “dark square” and “bright square” are the round (low-passed square) and reedy (high-passed square) waveforms found in divider organs. Big big influence was the Roland RS-09. And disasterpeace. So yes, that’s 72 oscillators smile
