The Monotrons by Korg are great fun to hack
Adding CV & gate allows easy sequencing


Korg Monotron - Duo Circuit Bending and adding CV/gate


Monotron Duo PCB soldering demo
  • This video is a response to a request on how to add CV control

  • I'm soldering onto the PCB the following leads:
  • 1. Orange: LFO input
  • 2. Blue (SQ2): ... square wave
  • 3. White (SAW2) ... ascending saw actually
  • 4. Red : (PLS1)... pulse
  • 5. Yellow: (SQR1)... square
  • 6. Green :Gate input
  • The CV input is just below this.(not in the video).
  • See below
