How can I turn a rack on and off via MIDI

I have an Alesis VI61 controller with a bunch of on/off buttons. I want to enable/disable Cantabile racks with those buttons. I can configure the buttons to be any CC on any channel. The buttons are stateful on or off (the light turns on when on, light turns off when off).

Background: Each rack in my current song has a MIDI routing/split configuration to 3 VST’s (pads, left side of the keyboard, right side of the keyboard). It would be cool to be able to switch between the different racks in order to play different instrument sets without touching the computer.

Edit:

Never mind, I think I’m going to try something out using MIDI route settings and/or bindings. Apparently, I had a similar question previously and I just looked through that thread lol
