Jump mode uses an absolute value based upon the position of the pot when 
edited: turn a pot and the value jumps immediately from the stored value to the 
edited value. 
Sustain: Norm +, Norm -, Arp +, Arp - —A momentary footswitch connected to 
Mopho x4’s Sustain input can be used either as a sustain pedal or to latch the 
arpeggiator. Mopho x4 can be configured for use with either normally open (+) 
or normally closed (-) footswitches. When set to Arp+ or Arp-, the footswitch 
will act as a sustain pedal when the Arpeggiator is off.  
Pedal: see table—Sets the destination for the Pedal/CV input. Note that this 
input is heavily filtered for clean operation, so there is a limit to the speed it will 
respond to changes.
