Finally updated DN2 to the latest OS to try and figure this one out, but I don’t have the right cable(s) to do so… So no better place to ask, than right here 
I’m wondering if this will work with the SP404? This would be awesome if it does? SP is class compliant so…anyone using it this way or can tell if it will work?
Will it work with the Xone 96? It’s also class compliant, but has a USB-B connection not a C like the SP.
from the manual:
13.6.4 USB OUT
Sets from where in the Digitone II’s signal path, the outgoing audio is routed to the class compliant
device. This parameter is only available when USB CONFIG is set to USB AUDIO/MIDI.
L:T1–16/R:T1–16 The outgoing audio is routed from the selected track(s) Press a [TRIG] key twice to
select a single track as a stereo source. The selected track’s [TRIG] key lights up white.
Press first one [TRIG] key and then another to select two separate tracks as sources. The selected
tracks’ [TRIG] keys lights up blue for left channel and red for right channel. The audio from each track
is then summed to mono, routed out and sent separately on left and right channel
