MacOSX : MIDI Device Name and ports suddenly changed.

Post by chapelier fou » Fri Jan 31, 2020 11:20 am

Here it is, I'm on Live 10, but for some reason I had to install and run Live 5 to check something.

The MIDI ports/Names of my Roland A-49 changed, and it's very annoying because it controls all my external gear.

Can't tell how it was precisely before,
but I used to have a port named "A-Series Keyboard (MIDI OUT)" and now I have "A-Series Keyboard (Port1)" and "A-Series Keyboard (Port2)".

In MIDI/Audio config, it won't let me remove or rename a port....

Found it. The A-49 has two "drivers" :
A generic one (class compliant) and the Roland one. For some reason this has changed. Reverting it to the Roland one gives the correct names.

It's because of the MIDI Routing panel in Audio/MIDI. It remembers every device, but you can just make a new profile or remove devices from the default one.
