Software can't communicate via MIDI with hardware audio interface

[Ellery]

Hello! I have a piece of hardware (audio interface) which is supposed to be controllable via a Linux-native, Electron-based software program that it communicates with via MIDI. The audio to and from the interface is fully functional and recognised in Jack, as are the interface's MIDI ports. However, the software, which is supposed to automatically detect the interface as soon as WebMIDI is enabled, just doesn't. Nothing happens.

I've tried adding all relevant group permissions for myself (audio, midi, dialout), but it hasn't solved the problems. No error messages show up in the terminal either.

For reference, the hardware is a MOTU 828 audio interface and the software is CueMix 5 (unofficial Linux build, downloadable from here - https://drive.google.com/file/d/1WFhmTM ... sp=sharing - per this forum page MOTU 828 (2024) - LinuxMusicians

According to both the creator of the software and other non-Zorin-based Linux users, the software is functional and connects successfully (including on Ubuntu 22.04 LTS) - so I suspect whatever the issue is, it's likely related to Zorin in particular. Any help would be much appreciated!

Thanks! Wasn't aware of this forum. Unfortunately there's nothing on there that addresses the issue I described above though (the app works differently with the Ultralite MK5 than it does with the 828, among other things)

i only ever used focusrite, for basic in out, but my friend i beleive uses what you have.... had a look at this ? - GitHub - Drumfix/motu-avb-usb: Linux USB driver for the MOTU AVB series interfaces

The AVB series is different, sadly. It's a frustratingly specific hardware/software combo - only the new 2024 model 828 works in this particular way with this software.
