In the video I said I'd put a stripped-down version of the MATLAB/Octave code here, but I can't because YouTube is complaining about angle brackets. So... go to the GitHub above to get the sq80waveproc.m code.

Freq11 = 2*Pitch
Gain11 = CN3

Freq111 = 0.5*Pitch
Gain111 = FootCtrl

Freq1111 = 0.25*Pitch
Gain1111 = Balance
Plus1111 = Control1

[Voice]
PreGain = MakeBus( FMAlgo:PreGain1, FMAlgo:PreGain111)

[Osc]

These are in via Soviet Space Child who had the following to say about them:

"I found these to be super fascinating. Both modules are very complex in their builds/engineering. The 291e on its own looks to be a lot more involved than a lot of modern day synths. Also it's pretty interesting how the 291e uses a discrete circuit through hole design, where as the 261e uses surface mount technology, even though both modules were designed at around the same time. In any case, Don Buchla was really a brilliant guy!"
