I plan to use the "footdrums" pedal - mainly just for the fun of it! And, to add a bit of a "live" sound to things. And lastly, 'cause my other 3 pedals are already assigned to things.
I'm not sure yet if I can get my left foot coordinated enough to play these percussion 'toys' well while I play - that could be a challange! I used to play organ, so I'll sort of think of it like tapping out a bass-pedal line rhythm ...
