Effect name: Slicer Distortion
Effect description:  Uses the slicer effect to distort the incoming signal, chop 
it up and send through different filters

Left pot label: Filter resonance
Left pot function: Sets the resonance for the filters 

Center pot label: Drive
Center pot function: Sets the drive of the distortion 

Right pot label: Speed
Right pot function: Sets the speed of the slicer

Left footswitch label: Bypass
Left footswitch function: Bypasses the effect

Right footswitch label: None
Right footswitch function: None
