I’ve only tried this a little bit, but it seems to work! In the manual on page 66, there’s this:
ENCODER DEST controls whether the DATA ENTRY and LEVEL/DATA knobs sends MIDI data or not. When set to INT, the knobs only affects the Digitakt and no MIDI data is sent. When set to INT + EXT, the knobs affects the Digitakt and also sends MIDI data to external devices.
Basically, setting this to INT+EXT makes every parameter on every page on the audio tracks send midi data, including pan. I tried this with FL Studio where I mapped the pan per track on the DT to their respective channels in FL Studio, and it worked! LFO and all.
You may also have to set the OUTPUT CH to track so that each audio track uses their own midi channels.
OUTPUT CH selects whether the knobs will send data on the auto channel or the track channel.
Does this work for you too?
