Roland GO:KEYS Bluetooth MIDI issues

[theatomicdog]

Hi!

I'm back to linux for music, thanks to the ability to run Reaper and EZDrummer3 (not the most opensource life but... they are really good). So, got a Bluetooth MIDI controller, compiled bluez https://mclarenlabs.com/blog/2019/01/15 ... pberry-pi/ to support it, and my other BLE devices work great but my new Roland GO:KEYS just won't do MIDI input/output. I see the connections in Alsa and Jack, I can connect, but won't send or receive notes. The Audio sink also works great. it is that the MIDI I/O does not work.
This all works when pairing with iOS.

So, my question is... does anyone have a Roland GO:KEYS workings as Bluetooth MIDI device with linux?

If you followed the tutorial that you referred to then whats does this command say avout the client number of your Midi keyboard?

Code: Select all

aseqdump -l

If the "client number" of your Midi keyboard is 128 then what does the following command output when you press keys on the Midi keyboard?

Code: Select all

aseqdump -p 128

Those are fantastic command line utils. I was doing all with GUI ones.
So, I tried again and... no dice.

Code: Select all

$ aseqdump -l
 Port    Client name                      Port name
  0:0    System                           Timer
  0:1    System                           Announce
 14:0    Midi Through                     Midi Through Port-0
128:0    GO:KEYS MIDI                     GO:KEYS MIDI Bluetooth

$ aseqdump -p 128
Waiting for data. Press Ctrl+C to end.
Source  Event                  Ch  Data

it receives nothing. So I went and started bluetoothd -d (debug) and found out that the handle_midi_io section is never triggered with this device

bluetoothd[7263]: profiles/midi/midi.c:handle_characteristic() Unsupported characteristic: 00000318-0000-1000-8000-00805f9b34fb

So I just collected a bunch of logs related to this and sent them to the bluez dev team for guidance on how to pull the information required .

On iOS works great though, so I'll see what can I do to debug/fix.

Wow! Really weird that it's recognized as a Midi device but aseqdump does nothing... Good that you informed the bluez devs.

Hello, I'm also trying to connect a Roland via Bluetooth MIDI and the bluetoothd program.

My bluetoothd fails with these debug logs:

Code: Select all

bluetoothd[10245]: profiles/deviceinfo/deviceinfo.c:handle_characteristic() Unsupported characteristic: 00002a2a-0000-1000-8000-00805f9b34fb

It appears in aconnect -io, in aseqdump -l, and in VMPK's list of MIDI input and output devices (as it should).
However, I can't send or receive any sound. It also doesn't appear in Ardour7's list of (ALSA) MIDI devices.

Any updates?
