DIY MiniTeensy Is An Open Source Polysynth, Based On Minimoog Synth Voice
Developer Nick Culbertson has introduced a new DIY synth project, MiniTeensy, that’s a 6-voice polyphonic VA synth, inspired by the iconic Moog Minimoog Model D.
“This project is a good representation of the surprisingly decent audio quality and limitation of microcontroller synths,” notes Culbertson. You can preview MiniTeensy via the above demo video.
MiniTeensy is an open-source project, based on the Teensy 4.1 microcontroller. The synth offers comprehensive synthesis options, with USB audio/MIDI and intuitive menu control.
Features:
- 6-voice polyphony with 3 oscillators per voice (18 total)
- 6 waveforms per oscillator
- Noise shared white/pink noise
- 24dB Moog-style ladder filter with ADSR envelopes
- Independent LFO with pitch/filter/amp targets
- Macro knob system – remap filter knobs to LFO controls
- USB Audio + MIDI – single cable to computer
- 20 hardware encoders + LCD for real-time control
- 20 Presets – 80s Brass, Saw Keys, Bass sounds, Pads, and more
- Multiple play modes – Mono, Poly, Legato with glide
The synth is available now as an open-source DIY project now on GitHub.
