Clock and transport

Manufacturer documented

PROJECT → MIDI → SYNC has separate CLOCK RECEIVE and TRANSPORT RECEIVE switches. Enable both when an external sequencer should supply tempo and playback control.

With both enabled, the documented behavior is to wait for clock after Start or Continue, for up to 16 seconds. A sender that supplies transport without clock can therefore appear unresponsive.

Audio tracks and MIDI tracks

Manufacturer documented

Audio-track TRIG CHANNEL assignments live in PROJECT → MIDI → CHANNELS. A MIDI track’s output channel is set on its NOTE SETUP page; an X means no MIDI channel is assigned.

Avoid assigning an audio track and a MIDI track the same channel when controlling external gear. The manual describes a collision: the MIDI track blocks the audio track’s output, while the audio track blocks the MIDI track’s input.
