SPECIAL FUNCTION PROGRAM CHART   

Programs 99 through 127 are special function programs and are described here:

 

 
Programs 99-106

 are used to increment or decrement the gains of any currently selected fixed gain or sweep gain 

programs.  The gains can be incremented/decremented by different step sizes depending on the chosen program such 
as 3dB at a time or 6dB at a time and so on.  Fixed gains are incremented/decremented as expected, and for swept gain 
programs only the higher gain side is incremented or decremented.  For example if OFF to 0dB is selected and increment 
3dB is selected the sweep range changes from OFF to 3dB.  Each time an increment or decrement is selected the gain 
again changes by that amount so the changes accumulate.  These programs work on the custom curves and pan curves 
as well as the fixed gains and sweep gains.  

 
Programs 107-118 

are used to disable the gain function altogether (output mutes) and instead converts either the MIDI 

CC in or expression pedal to a MIDI CC message on the MIDI OUT port.  This is useful for controlling additional MIDI gear 
if you have a limited number of expression pedal inputs on your controller and need more controllers.  
 

Programs 119-125 

are custom curves that are located in non-volatile memory.  The usual curve used in all the Volcano 

programs is a traditional straight line log curve which is the same as standard log type (volume) pedal.  The custom 
curves offer alternate curve shapes that vary from the norm.  These can include a more aggressive volume change at the 
beginning of the sweep and less aggressive change near the end of the pedal travel, or an insensitive area near the 
beginning and more aggressive rise in volume starting from the center of the sweep and so on.  Any shape curve can be 
saved here using sys-ex messages and custom curve editors.  We are hoping to offer an editor in the future although 
plans are non-specific at this point.  Currently all 7 curves are loaded with various shapes you can experiment with. 
 
To use the custom curves, first select any of the sweep gain curves (with the exception of the pan curves), then select a 
custom curve.  The curve will work with the selected gain curve to offer you a new shape with the range selected by the 
sweep gain curve program.   You can also use the inc/dec programs or boost controllers to change the endpoint of the 
sweep after you have selected the custom curve.  
 

Programs 126-127 

are used to enable/disable the Softchange feature. This unique feature, when activated, will rapidly 

sweep the gain from the current gain to the newly selected gain when programs are changed.  This applies equally when 
going between fixed gains, between swept gains, or between fixed and swept gains.  The change is fast enough to be 
called "instant" yet will smooth out transitions caused by rapid gain changes especially if an instrument is still being 
played during a gain change.  Disabling Softchange will force the unit to change gains absolutely instantly with no 
sweeping between gain changes.  Both settings still only change gains at zero crossing times for the quietest changes 
possible.
