Using GPI (General Purpose Interface)
The rear panel GPI (General Purpose Interface) connector can be used as an input/output
connector. This connector provides five GPI IN ports and five GPI OUT ports. For example
you can use an external switch to control internal parameters of the CL series console or to
switch scenes. Conversely, operations or scene changes performed on the CL series console
can send control signals to an external device.
For details on how to send control signals to an external device when you switch scenes, refer
to “Outputting a control signal to an external device in tandem with scene recall (GPI OUT)
(page 109).
Using GPI IN
You can use the GPI IN ports of the GPI connector to control the parameters of the CL series
console from an external device. For example, you could use an external switch to turn the CL
series console’s Talkback on/off, operate the Tap Tempo function, or switch scenes.
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.
