Depending on the type of switches used by the TC Helicon Switch-3 it should work as long as they are momentary switches and you’ve used the BeatBuddy (BB) pedal settings to detect the type (either momentary on or momentary off). The latest BB firmware version will work best with the momentary switches although I think it still detects and recognizes the latching type. The BB also expects a TRS type patch cable.
You can set the BB remote foot switch settings Suggested Remote Foot Switch Settings and IIRC, you hold the switch down to select a song or folder and then you can scroll up or down using a tap.
