Arduino MIDI footswitch, Reaper and TH-U. Newbie question

[xmioimx]

Hi guys,

Starting a project to build a footswitch pedalboard based on Arduino to control TH-U in Reaper. It's my first Arduino project so I am learning everything (Arduino/MIDI) from zero. So far I've managed to send MIDI signals to the PC, now working on Reaper and TH-U to read them.

I am still thinking on how I would like it to work, and one feature that would be amazing is to have leds that will show the status of the effects when a patch is selected, or even change when using automation. Dual-colored leds would be a killer. Off if a footswitch is not assigned, green if assigned but off, red if assigned and on

The question is: is it even possible to 'read' the status of the effects/parameters on TH-U?

Cheers
