An awesome list of open source synthesizer projects.
- Modular
- Audio source (things that can generate frequencies above 20Hz)
- Audio processing (filter, amplifier, ring modulator, frequency shifter, waveshaper, distortion)
- Modulation source (LFOs, EGs, gates, triggers, random voltages, offset generators)
- Modulation processing (logic functions, sample and hold, slew limiter, comparator, inverter, quantizer)
- Routing (mixer, switch, mult)
- Audio effects (delays, DSP, phaser, pitchshifter)
- Other/utility (oscilloscope, lights, MIDI-to-CV, etc)
- Full Voice
