SWEEP GAIN PROGRAM CHART 

 
Programs 47-90 are used to select a range of gains that the unit will sweep through when the MIDI CC0 pedal or the 
expression pedal is swept.  The loudest end of the sweep can be changed after it is selected using the special function 
programs increment and decrement or the on/off inc/dec messages.  
 
Programs 91-98 select pan sweeps that have an appropriate pan curve and will only be used if two or more Volcano 
units are used in a panning setup.  See the Tech Tips section for using panning.
