- Worth noticing
- The page says every instrument is tuned to one scale, so combinations stay harmonically compatible.
Field notes
The interface offers a metronome and optional soft backing chords, alongside a control for switching between playing and audience listening. Keyboard input is split across low, mid, and high ranges, with Shift marked for accents. Although the page presents the hall as live, the captured state is waiting for a connection, so the extract does not establish that a session was available at the time.
