# Test synthio without hardware

Build the unix port then run `....../ports/unix/micropython-coverage midi2wav.py`.

This will create `tune.wav` as output, which you can listen to using any old audio player.
Add a manual test of synthio this allows to test how the midi synthesizer is working, without access to hardware. Run `micropython-coverage midi2wav.py` and it will create `tune.wav` as an output. 2023-04-23 09:24:17 -05:00			`# Test synthio without hardware`

synthio: Add synthio.Note This class allows much more expressive sound synthesis: * tremolo & vibrato * arbitrary frequency * different evelope & waveform per note * all properties dynamically settable from Python code 2023-05-01 09:41:05 -05:00			Build the unix port then run `....../ports/unix/micropython-coverage midi2wav.py`.
