My first attempt at using microcontrollers for audio synthesis.
Both notes/velocity and controller change is done via MIDI.
Functionality
Two oscillators with independent volume and tune
Square, triangle and saw waveforms
ADSR envelope
Arpeggiator
Hardware
The hardware can be made extremely simple due to the microcontroller featuring a built in D/A-converter and DSP with enough power to do all audio processing.
