The train rolls toward a musical signal, then waits. Play the written note shown above the engine and hold it for about a third of a second. The light turns green and the train carries on. Clear 12 signals to reach the station.
Touch mode: hold a note button or use Q, W, E, R, T. Microphone mode: choose your instrument, enable the microphone, and stay quiet for the room check. Wrong notes leave the train waiting. Release or breathe briefly between notes.
Trumpet circles show valves 1–3. Sax circles show left hand 1–3 and right hand 4–6; O is the octave key. Filled means pressed.
Pause, switching tabs, or changing instrument stops microphone capture. Re-enable it to continue with your instrument. Real trumpet/saxophone and iPad microphone performance still needs hands-on testing.
