Mutable Instruments Braids[modifier]
It’s a hidden oscillator model that plays morse code. To get the mode as an additional oscillator mode you need to enter 49 in the built in text editor. It can be found on one of the last pages of the Braids settings.
Here is the initial text:

Now the new oscillator model is available in the list of oscillator models.
