With the Monotron set to drone and the LFO free-running, taking the gate into the top of C9 on the circuit board resets the LFO, but only lets the LFO go on keyup. Suspect that the gate needs to be converted to a trigger before being fed into the reset point - am guessing that's what C9/R24 is for.

How do you get it to work with the keyboard?

@ultimatenerd22 keyboard is a Roland SH-5 with cv/gate outputs, no MIDI. The cv/gate outs were tied to particular points on the Monotron circuit board.
