I have a Yamaha P-115 keyboard with USB MIDI output. I setup Zynthian on a Raspberry PI v4 with no other hardware, so was hoping to get the keyboard recognized through the USB. Unfortunately I cannot seem to get Zynthian to recognize any MIDI input at all coming from the Yamaha. The MIDI log is completely blank.
I entered this in the Zynthian terminal to see the connection properties:
amidi -p hw:0,0,0 -d
Here is the response:
ALSA lib rawmidi_hw.c:233: (snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: Device or resource busy cannot open port "hw:0,0,0": Device or resource busy
Any thoughts as to what else I may need to configure in order to get Zynthian to recognize MIDI input coming from the USB?
