PitchFactor User Guide Expression Pedal
34
Note: The Expression Pedal input supports control voltage inputs from 0V to 3V. Care must
be taken to avoid ground loops when using this input with external control voltages. If you
hear a “hum” only when you’ve connected a control voltage source to PitchFactor’s
Expression Pedal input jack, then it is likely that the device generating the control voltage is
grounded to a different ground than your audio ins and outs. Ground loops are notoriously
difficult to track down and beyond the scope of this User Guide to diagnose.
