Arrangement mode and MIDI triggering via Digitakt

Hey all,

I can't for the life of me figure out how to trigger clips in arrangement mode for live performance (I'm trying to potentially use the DTII like an Ableton Push). I've tried both using the CCs and MIDI mapping. Any suggestions on how to orient this?

Basically how I want to set up the DTII is for the midi channels to trigger various tracks during my set.
