This pedalboard does not produce any sound. Instead, it just shows example how to get three types of CC plugin on-off controls (Latching, Momentary, Inverted Momentary) from the regular MIDI notes provided by FCB1010 with a stock Behringer EEPROM firmware. This workaround approach is required because of the stock FCB1010 being to dumb to work in a Stompbox mode, and as result being not able to enable-disable effects with one footswitch in the most workflows . This whole pedalboard is a workaround for this FCB issue. (Some people prefer going with UNO or EurekaPROM firmware instead to fix it) Also it can be used as example of how to control CC assignments with a midi keyboards notes as well, I guess.
