Just tried using my old Triton LE MIDI keyboard, I can record notes into cubase but when they’re played back the audio sounds like there’s a really long attack, and the sound becomes quiet and sustained, like the MIDI needs resetting when a notes doesn’t receive it’s off signal, if I change the patch on the keyboard and back again it starts working correctly but then goes back to not working correctly after a few notes. This is with Cubase 14, I tried doing the exact same thing with Cubase 12 and the MIDI plays back properly. I’m using an RME fireface UC as the MIDI interface on macOS Sonoma.
I reinstalled Cubase 14 and the latest RME driver but same thing, retested, works in Cubase 12 but not in 14 still.
Edit - I’ve set up a MIDI bus on macOS to send the MIDI out and then record it back in on another MIDI track to get an idea of what’s happening, I can see that the first note cubase plays, it doesn’t send an off signal so the note gets sustained, this seems to happen when it’s recording a loop. basically I have one long note playing constantly when ever I use MIDI. It also shows that it’s recording cc73 attack time data for some reason, I literally only recorded key presses. I can’t recreate the sound that’s coming out of the keyboard by just hitting notes alone when it’s reset, so it seems something weird is being sent to the keyboard that’s having a strange effect, it’s hard to tell what’s happening. I checked all the MIDI settings in preferences and everything matches Cubase 12’s settings.
