"This is a superb modification of the Korg Monotron to turn it into a 'real' synth with powerful enhancements. From Beatnik's Japanese page:

Monotron++ is modified version of Monotron that come from Korg. 'MIDI-IF', 'VCA' and some other things are added onto it.
'MIDI-IF' allows you to be able to control Monotron++ by keyboard. VCA works as noise gate. But you can use it by external cv to control its expressions (option). The schematic of VCA is also based on MS-20. It's getting to be almost MS-20 clone now.
All the information for modifying is opened for anyone else of the world.

I add 4 parameter to Monotron++

Glide
VCO Wave form selector Switch(SQR / SAW )
Pulse width for SQR Wave
EG/LFO switch
Output Volume (for recording out)
