"I modified this MG-1 a few years ago. Don't ask for schematics or anything, as I don't think I kept my notes. These are basic modifications, anyway, for anyone who knows what they're doing.


Here is the list of modifications, and/or updates/work done:

LFO - added Medium, Fast, (S)Low speed selection switch

Osc 1 - added Pulse Width knob, plus Pulse Width routing switch (manual, LFO)

Osc 2 - added Pulse Width knob. Added Detune Routing switch (LFO, Envelope, off or manual). If memory serves, Osc 2 was also lowered an octave.

Filter - added Feedback knob, plus a switch to turn Feedback on or off.

A Power LED was added.

Keybed - each key removed and hand-cleaned. The keybed was adjusted to be quicker and more responsive.

CV inputs - modded to accept standard 1v / octave analog control.

New audio output IC (I forget what I put in there, but it's new and better than the stock one).

Standard 1/4 inch output jack replaces stock RCA output jacks.

Lower PCB inside reinforced to be more structurally stable.

Complete power supply overhaul.

Electrolytic capacitors replaced.

Various switches and sliders replaced with new ones as necessary.

Fully tuned and calibrated.

All foam removed and foam damaged components cleaned and, if necessary, replaced.

All plastic and metal hand-cleaned of gunk, nasties, and yuckies (I'm a germaphobe)."
