I'm trying to run a PD patch that is effectively a sequencer that can control a hardware synth via MIDI. The patch works when running PD on my Macbook. The signal chain there is: Pd patch -> Tascam US-122MkII (audio/MIDI interface interface here being used as my MIDI interface via USB) -> Volca Keys (via 5 pin MIDI cable).
However when uploading the patch onto the Bela and running it, I'm having some problems. Firstly my Tascam Interface won't even light up its 'power' ("USB") LED. Which suggests to me that it isn't getting enough from the Bela to run. I'm also getting the following messages in the console when running the patch:
Trying to open MIDI devices...
MIDI device hw:1,0,0 is not ready: No such file or directory...
done opening MIDI devices
MIDI device hw:1,0,0 is not ready: No such file or directory
Is this simply because the Audio interface isn't being powered? How can I get around this? and If I do manage to power it is there a way to set the MIDI preferences of the Bela/BBB within the IDE?
Thanks for any help.
