I can modify your Monotron to accept cv/gate signals so it can be controlled directly by an analogue sequencer, or through midi via a cv/gate converter.
You’ll get an external box with a seperate cable (as obviously the Monotron is too small to include all the parts) that can be taken off so your Monotron can be used as before. it's a standard S-video cable, so you can replace it. both the box and the monotron have 4-pin DIN input connectors.
The box includes inputs for:
-gate signal (5V)
-CV signal for oscillator pitch
-Cv signal for filter
-a switch for filter tracking
-a potmeter/ trimmer to adjust pitch cv
The box is connected to the Monotron with a 4-pin mini-DIN cable..."
