Pedal order switcher and a remote control via TRS

[victorlee335]

I am doing a project - making a pedal order switcher (i.e flip-flop) that has a remote out to be controlled by a TRS switch on my Musicomlab. I can't put the flip-flop on the pedalboard due to lack of real estate, so I am putting it underneath the board and wishing to trigger it via a function switch on the Musicomlab.
My friend already has a schematic that utilizes a relay and a micro controller. But I was wondering if it was possible to use a TRS to trigger it...
