Using Gpi Out - Yamaha QL5 Reference Manual

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. They can be saved
as SETUP data.
