FAQ
Nothing happens when I tap a marker.
Make sure your MIDI connection is active and your DAW is configured for MTC/MMC as described above.
Also confirm your DAW is stopped when tapping a marker (locate is intended for stopped state).
Network MIDI disconnects sometimes.
Try USB if possible. If you prefer network MIDI, keep the iPad awake and avoid switching Wi‑Fi networks.
