Hi Joe, I’ve thought about this a bit and I think the following solution would work well for what you want.
I think it may be best to dedicate some of the buttons on the DataLooper to doing the track or chain switching.
I would personally put all the different FX sets on different chains inside an Audio Effects Rack, then reprogram the DataLooper to send out control changes.
You would map 3 of the DataLooper buttons to the same CC, and then the lights will automatically turn on/off depending on the last value sent.
This way, you can use the DataLooper to select which FX bank you want to be on, then record loops, without dealing with a computer. I use this same sort of thing to switch presets for guitar FX.
