I'm using Mobius, and controlling it with a USB Midi Footswitch

compact, relatively inexpensive. Simple to setup. I set the three switches to
Record
Overdub
Next Loop
on whatever track is selected. I setup TouchOSC to send MIDI to Mobius. With it I can select the track by reaching over and touching the track I need. I can also quickly mute tracks, which can kind of create a DJ effect. I've attached a screenshot of my TouchOSC setup.
Hopefully this is helpful. I tried all of the different loopers, and Mobius was the only one that did everything I needed it to do
