Recording MIDI on Tracker+ with Play+

I own both “Plus-machines” and I’d like to record the beat-fills on the Tracker+ that you can sequence on the synth-/midi-tracks on the Play+.

What is the easiest way, step-by-step to make this, say for example I have a kick on instrument one on the tracker and the Play’s “Kick-fill” is on midi-track one, what do I do then? :sweat_smile:
