Mother of Moog Werkstatt Mods - teaser.


Published on Oct 19, 2015 Peter Churchyard

"The announcement of the Moog Mother 32 semi modular synth gave me the idea to re work the mods I had made before to my Werkstatt. The idea is to try and get close to the specs of the Mother 32. So I am calling this mod - 'Mutter zweiunddreiƟig' :)

Basic Mods:
Use cpu from an Arduino UNO to control the Werkstatt.
Control the keyboard logic and D/A convertor so the cpu can 'play' notes. This includes a +1 octave and a +2 octave circuit to give 4 octave 'digital' range.
Added leds for status indicators.
Added Midi in and output.
Added level shifters so the cpu can read the LFO rate, VCO freq, vco PWM and filter cutoff knobs.
Added level shift to read LFO voltage by cpu.

Still in progress:
Add extra low profile switches to control the cpu functions.
Add PWM - CR filter to cutoff to allow simple filter cutoff control.
Read the key matrix so can control cpu/send note data via midi.
Add PWM - CR filter to give semi tone pitch 'bend'

I will be posting more info at http://moddersandrockers.com/werkstatt
