## Play it from code

Instruments use the same C ABI as effects, plus note input: `sournd_engine_note_on(e, note, velocity, sample_offset)`, `sournd_engine_note_off(e, note, sample_offset)` and `sournd_engine_all_notes_off(e)`. In JUCE, the bridge feeds your `MidiBuffer` straight in. See the [C ABI reference](https://sournd.com/docs/abi/index.md).
