FSI

Footswitch and Expression Pedal Interface

At 4HP, the FSI module is a compact foot controller interface useful for both live performance and recording. The expression pedal portion allows you to send up to 3 control voltages ranging from 0-10V, ±5V and ±2.5V, with a fourth outputting the inverse of the selected voltage. This lets you sweep filters, crossfade between patches and control dry/wet mixes, all while your hands are busy turning knobs or plucking at strings. The footswitch portion of the module outputs three +5V gates with a fourth outputting the inverse of that gate (0/+5V).

Most passive expression pedals with a potentiometer output at the Tip of a TRS cable will work. The FSI has a polarity jumper on the back of the module in case your pedal doesn’t have one of its own. The FSI was designed with a normally “closed” passive footswitch in mind (such as the Yamaha FC-5), but the inverting output will function normally with an open switch, so most pedals can be accommodated.

Note that this module is meant to only take passive foot controllers.
