Import WAV (Ctrl+I) creates playable clips; Add region creates silent placeholders.
Record captures JACK input to a chosen WAV; Stop finalizes and adds the take.
Save the project after recording. External asset paths must remain available;
select a missing clip and use File/Relink selected audio to repair it.
Add MIDI clip on an existing track, then open Piano roll (Ctrl+4) to draw notes.
Connect a MIDI source to the JACK `midi_in` port for live playing; Panic/F9

With JACK development files and an existing JACK-compatible server, run the
isolated software-loopback test with `make test-jack` and the record/reopen/play
acceptance test with `make test-jack-audio`. It connects only test
acceptance test with `make test-jack-audio` and MIDI acceptance with
`make test-jack-midi`. It connects only test
clients. See [engine documentation](docs/AUDIO_ENGINE.md) for configuration,
