From the project

ADSR Envelope Extension of the original AD9833 Waveform Generator FeatherWing

Example MIDI synthesizer and sweep generator code is provided in the repository (sweep example video: https://youtu.be/O1vMfLoCWzg). MIDI synthesizer and sweep generator code was tested with a Feather M4 Express using CircuitPython version 4.1.0 rc-1.

MIDI note input was received by a Classic MIDI Interface FeatherWing from a variety of MIDI sources. See https://github.com/CedarGroveStudios/ClassicMIDIFeatherWing for details.
