NOTE • With latched operation, the function will switch between active and inactive each time a trigger is input from the external switch. In this case, we recommend that you use a non-locking type of external switch. • With unlatched operation, the function will be active only while the signal from the external switch is at the high level or low level. In this case, you may use either a non-locking or a locking type of external switch as appropriate for your needs. • Settings in the GPI page of the MIDI/GPI screen are common to all scenes.
