Bypass; Using The Foot Switch - Alesis ModFX Bitrman Reference Manual

Bypass

This button sends the signal directly from the input to the output
without any effect. Press [BYPASS] to check the sound of the
source without any effect from the Bitrman. When the red
BYPASS LED is lit, all effects are off. Bypass can also be
activated by the foot switch.
Since the Bitrman is a digital effect, signal always passes through
the digital A/D–D/A conversion process, so that digital signal will
flow through to other effects in a ModLink chain even when
[BYPASS] is on. So, unlike old analog effects, this is not a
"hardwire" bypass switch—the Bitrman must be powered on to
pass signal through, even in bypass mode. Similarly, the [TRIM]
control is always active, since it's an analog control regulating the
level feeding the analog-to-digital converters.

Using the Foot Switch

If you need to bypass the effect totally but your hands aren't free,
simply connect any momentary footswitch (such as those used for
keyboard sustain pedals, either NC normally closed or NO
normally open) to the [FOOT SWITCH] jack on the rear panel.
The footswitch will turn the BYPASS LED on and off.
