You can connect either a single button momentary footswitch or a TC-Helicon Switch-3 footswitch to allow handsfree control of Harmony-M. A single button footswitch remotely toggles only the ON function.
The Switch-3 footswitch controls A/B, BYPASS and ON functions from left to right. The footswitch must be connected at power up for Harmony-M to recognize
whether it is a single or triple function footswitch.
MIDI Setup mode and Preset select are not possible with the footswitch.
