My Teensy Monotron Mod [a.k.a the nostromotron]


This is a recap of my mod for original monotron.

Originally, I wanted to use a Teensy 3.0 to implement a cheap MIDI control of the monotron, and turn it into a real sequence-able instrument rather than just a play toy. In the end, I discovered that adding a mcu hooked to the monotron allowed me to extend the monotron a lot more and turn it into a deeper synth. The mod contains the following features:

  • USB compliant midi interface
  • Additional digital oscillator with selectable waveforms
  • Toggle analog / digital oscillator
  • Envelope for the filter cutoff and the digital oscillator
  • Portamento

All controls being accessible through MIDI continuous controllers.
