Mostly, the modules used in this project were designed by people from the
Synth-DIY list or other random sources found on the internet.
A slight few are homebrewed designs which might or might not be crappy. Anyhow, these
are the modules, as shown in the picture, from left to right:
- PSU voltage LED indicators - the PSU is ripped out from a roland S-50
and gives +5, +6.3, +15 and -15 volt with analog & digital grounds separated.
- Keyboard tuner - for our resistor-ladder keyboard, outputs gate and cv and has a simple glide.
Notice the incredibly fancy safe-style knob for the tuning, it's even
lockable! Based on the formant.
- USB & MIDI -> CV - homebrewed design, very crude so far. Converts midi signals incoming on the USB ch1 to
cv/gate and gate only on ch2. MIDI-in support not added yet
- 4069 VCO -
square and saw out, by Ren?chmitz.
- 4069 VCO with modifications -
square and saw out, by Ren?chmitz, tri and "sine" out
waveshaper
by Scott Gravenhorst.
- Suboscillator - extremely simple, based on a logic counter
- White noise - by Ren?chmitz
- Dual ASM-1 LFO
- simple square and triangle LFO by Magnus Danielson and Gene Stopp
- Empty faceplate - for future stuff
- ADSR - simple homebrewed (mix-a-lot-of-schematics technique) ADSR with normal & inverting out.
Old and really, really crappy.
- MS-20 VCF Clone - by Ren?chmitz
- 2 x 2 x CV-Mixer - based on the mixer-schematic by All Electric Kitchen
- Dual SSM2164 VCA
- by Mike Irwin.
- Banana to phono converter - ummm.... figure it out.
External add-ons
- CV pedal - opto-controlled seamless CV pedal with range knob
- "Light theremin" - CV-generator based on a photoresistor, exists on a breadboard every now and then.
*extremely* simple; a photoresistor + resistor.
Things to come
- "Light theremin" - one that doesn't exist temporarily on a breadboard.
- Multi EG - 8-point envelope generator
- Ring modulator - any design really
- 3-d joystick + 1 - i have these really weird joysticks from a 70's video game that can move in
3 dimensions + turn left & right. Calculations gives about 8 octaves of control using trinary systems.
- Modulation wheels - external in a box
- And much, much more...
