For more complex RC-300 Presets, it's occasionally useful to control Loop FX using BOSS FS-6/FS-7 and FS-5U external footswitches. This article will cover going up and down thru all of the different FX Categories/Types available, as well as turning Loop FX on or off.
To scroll up and down thru the different effects programs available on the RC-300 using an external footswitch connected to the CTL1,2/EXP2 jack on the back of the RC-300. You will need to use both switches of the FS-6/FS-7. One for going up, and one for going down thru the different effects.
To Assign a function to scroll up and down effects programs:
NOTE: There several Effect Types for each Effect Category, so when you scroll thru them, you will be pressing the switch several times to go thru the multiple Effect Types available within each Effect Category before you get to the next Effect Category.
(NOTE: The CTL 1 assignment will be controlled by the "B" pedal of your FS-6, and the CTL 2 assign will be controlled by the "A" pedal. This is how the pedal is wired.)
