Two MIDI Express 128 cause Cubase to freeze on exit

Post by ColdSteel »

Hey guys,
I'm running into a weird problem on my new studio PC (Win11) which I didn't have on my old machine (Win10). I'm using two MIDI Express 128 which worked fine so far but now I have the problem that in 50% of the cases when I exit Cubase Pro (12 or 11, doesn't matter), the software freezes. As soon as I unplug one of the MIDI interfaces, Cubase magically closes itself just fine. With just MIDI Express A connected to the PC - no problem at all. With just MIDI Express B connected to the PC - no problem at all. I'm using MOTU's latest driver and tried different combinations of USB ports but it's always the same result.
Any ideas? Thanks in advance!

Glad that someone else noticed the same issue! I ended up keeping the unit disconnected when I don't use the external instruments that are connected via MIDI.

I bet it has something to do with drivers / USB management of the device on modern computers. Drivers are outdated and I suspect the MIDI express 128 is not working well with USB3 ports / cables, in fact I reported other issues here: viewtopic.php?t=70184
