Moog Grandmother plus Eight!


video upload by Peter Churchyard

"Moog Grandmother plus eight Moog Werkstatt.
Schematics and Software at 'http://moddersandrockers.com/werkstat...'
The Werkstatt have my midi mod that takes over the keyboard logic and is driven by an Arduino. There are two quad units. The Arduino uses a few switches to control the many different note routing methods. The main modes are Unison and Individual. One mode only cycles through three of the Werkstatt and another treats the Midi out as up to four other instruments."

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

LittleBits Broomstick Guitar


Published on Oct 18, 2014 Peter Churchyard

littleBits synth kits on eBay

"By taking an Arduino microcontroller and adding two RC filters the cpu can control the LittleBits Korg Synth (http://littlebits.cc/) components. Add a PS/2 compatible mouse and you have a fun instrument. More at http://moddersandrockers.com/littlebi....

The mouse with its two axis of control and three buttons allows for a fun interface. This version is the first that has the note bending feature. I will be adding an opto isolator so the controller can read MIDI data. This will allow me to play the LittleBits Synth kit using MIDI.

At the moment I have not trimmed the CV scaling to give correct note spacing but it is close enough for this demo."
