Hello Arlo,
First, I just got a tip from someone in the Nord Forum to switch on Developer Mode in Android. Did it, and could select MIDI as standard mode for USB. Still, no success with the MIDI Messages.
Yes, I can see Midi messages, and yes, the trigger to set the messages upon song selection is switched on (besides, you can do this manually when clicking midi in the Midi Presets, it doesn't work either).
Now, what I saw is that there is obviously an error (?) while setting up the virtual Port in BandHelper. No idea what that means or what I can do against it. see the Activity Log:
added port Clavia DMI AB Nord Stage 3 for input
sending data [B5, 00, 00, B5, 20, 00, C5, 03] to port Nord Stage 3 MIDI Input
adding ports for virtual MIDI
error adding port virtual MIDI - BandHelper for output
error adding port virtual MIDI - BandHelper for input
However: as connected Ports, "Clavia DMI Nord Stage 3 (input)" and " [...] (output)" are set above in the Midi status with the remark MIDI Running.
Any idea?
