Field notes
The interface exposes controls for tempo, scale and mood, rhythm, effects, and recording, alongside a guided tour and demo replay. Recording options include a last-eight-bars capture, channel-separated WAV files, MIDI, and video formats; the page also says the metronome click is heard only by the player and is not included in recordings.
