I’ve been using the MiniLab mk II primarily with PiSound/RPi 3B+/Patchbox/MODEP, as well as a few other Linux images like SamplerBox, for several months now and haven’t been able to quell an occasional issue present in any MiniLab/Linux combination–“stuck” midi notes/missed midi-off messages. There are forum posts talking about this issue with some Arturia midi controllers, Linux-based systems, and specifically midi-over-USB. Some people have been able to resolve the issue by switching to din midi, but the MiniLab only has the USB option. Some in these forums also found a solution waiting out a firmware update from Arturia. I’m running the latest Arturia firmware on the MiniLab, and the latest stable image of Patchbox/MODEP.
I’ve added an Arturia BeatStep to the mix in the last few weeks and have not had any issue with that controller so far. They’re both being recognized by amidi -l (I’m learning, but am still pretty rudimentary around the cli). I also just reached out to Arturia support, and they reiterated that they don’t support Linux, but to try using a powered USB 2.0 hub (which I’ve tried) among some other BIOS solutions to mimic USB 2.0 on newer ports.
I really like the small format on the MiniLab, with 16 knobs and pads for interfacing with MODEP and the like, but this issue makes performance with the MiniLab too much a gamble. I’m not against upgrading the gear in the near future, but nothing I’ve found so far has matched the size/parameter controls I’m looking for, and how cool would it be for there to be a Linux-based solution to this issue. I’m happy to provide more info and test things out.
Thanks for reading and for all the great work happening in this community!
