iPad app
- Needs iPadOS 15 or later. It works offline and has no account.
- Piano mode and lessons work with the on-screen keys. Editing patterns in the tracker needs a hardware keyboard (such as a Magic Keyboard).
- A USB MIDI keyboard works through USB-C, or a Lightning camera adapter on older iPads. Turn MIDI on in the top bar. Bluetooth MIDI keyboards are not supported yet.
- With a ROLI LUMI plugged in, the keys to play next in a lesson light up.

I hear nothing. Tap the button on the start screen to start audio, and turn up the volume. The app plays with the silent switch on.
