I bought an OP-1 and it is the best product I've ever used. However, I was wildly disappointed to find the MIDI control input doesn't work with ALSA sequencer consistently (I need this functionality for a programming side project). I submited a support request, but it's kind of frustrating that I don't have the capability to just fix the firmware myself. (Specifically aseqdump only works after restarting the computer and RtMidi qmidiin doesn't print anything and also prevents aseqdump from working if called..., if anyone knows why I'd love to understand)

That's too bad! I've used the MIDI and it works well albeit I've only written things in using WebMIDI not the ALSA sequencer. I'm really curious about your side project, would you mind sharing it?

  For sure! I'm working on an open source gameplay framework and one of the 'upgrades' I'm planning is MIDI based manipulation of trees of gameplay values at runtime from knobs. You can read more here https://wesxdz.dev/bicycle-mango https://wesxdz.dev/bicycle-mango

I SOLVED IT~! I was trying to run one of my old games using wine and SDL debug logged that MIDI would not work because of 'Unknown SEQ default' (sorry for lack of detail, I took an image of the output instead of saving the text -_-) Installing the amd64 version of libasound2-plugins resolve the issue. Not sure why this is not the default on KDE Neon... https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/672680 https://answers.launchpad.net/ubuntu/+source/alsa-driver/+qu...
