Korg’s Monotrons are a great toy. Especially because they were obviously build modding friendly. I modded both this Monotron Delay and a normal Monotron. Both toys were turned into an awesome, but still not to serious synthesizer.
The feature list
- replaced all the fiddly pots with normal sized ones
- replaced Monotrons toggle switch (off - triangle - square) with a new switch
- put the LFO LED to the front
- added the missing pitch control pot (the Delay comes without it)
- added the missing resonance control pot (the Delay also comes without this)
- added patchpoints for CV, cutoff frequency, gate and external in (check dinsync)
- added a simple switch to choose the LFOs target, this can now go to cutoff, pitch and delay-time
- added a PitchWheel, which can be patched either into pitch or cutoff
- added a little “sampler” based around the ISD1820-chip. This gives a nice extra!
- added switch to choose between LFO mode between one-shot EG and LFO (check houshu)
- added feedback, the output going back to the input through a simple diode
- removed R11 to avoid the gate voltage affecting the pitch. Also puts Monotron in “Drone-Mode”
- switch to turn VCO off (check houshu)
It really is too bad that I never took a picture with the thingies on the sliders …
