CONTROL CHANGE MESSAGES
The GFC-50 can accept connection of a maximum of two external expression pedals
(Roland EV-5: optional) and two foot switches (BOSS FS-5L/FS-5U: optional). This allows
you to control a connected MIDI instrument in real time with Control Change messages.
The Control Change jacks on the rear of the GFC-50 correspond to the following
Control Change numbers:
Expression Pedal
EXP 1: Volume (#7)
EXP 2: General Purpose Controller (#16)
Control Peal
CTL 1: Hold (#64)
CTL 2: General Purpose Controller (#80)
* “#” represents a Control Change number.
fig.12
* Either a latch-type (FS-5L), or momentary-type (FS-5U) footswitch can be connected to each CTL Jack.
Latch Type: Pressing the pedal turns a connected unit (or function) ON or OFF.
Momentary Type: Only while the pedal is being pressed, the ON/OFF status can be changed.
Use only the specified expression pedal (EV-5; sold separately).
By connecting any other expression pedals, you risk causing malfunction
and/or damage to the unit.
