Hi pharaoh0 , and welcome on this board.
Yes the Drumbrute Impact can be synced to other devices as a slave.
Sync can be done by USB, MIDI or CLOCK signals.
So in i mind, i assume you would control the DrumBrute Impact with a midi foot controller/pedalboard.
Don't have one at the office, but it would require the Drumbrute impact and the controller to be set on same MIDI channel, having connected Pedal board midi out to Drumbrute Impact Midi IN,
set MIDI impact sync mode on MIDI.
Sorry for not being able to provide more help, but it should work! If you have a reference to share for the midi foot controller, i'd be happy to investigate.
cheers,
