Still a work in progress for sure...
Using my audio interface (Focusrite Saffire Pro 40) as a mixer (would like a stand alone mixer eventually for computer-less performance).
MIDI out from the Digitakt into my DSI OB6 which has MIDI thru to the Waldorf Pulse 2 and that in turn goes into my Moog Mother 32.
Using my Alesis VI61 into my audio interface, I can output MIDI on channel 14 from that into the Digitakt. This allows for me to easily audition and record sequences in the Digitakt's MIDI tracks (the keyboard controls whatever track is currently selected).
Typically I'll have my OB6 on MIDI A, Pulse 2 on MIDI B, and Mother 32 on MIDI C. Hoping Elektron gives us the ability to save our MIDI settings so it will be easier to set these up for different songs and patterns.
Still waiting on my Digitakt stand I ordered from Fraction Industries
