Weird MIDI issue Cubase 14

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.

I’ve added a filter to block MIDI channel 73 and it seems to have fixed the issue, I’m not sure about the sustained note though, maybe that only happens when re-routing the MIDI back through and when it records to the end of the loop and re-loops.

Something weird going on with MIDI cc73 though, not sure why Cubase is recording data on it.

Everything work fine if you start with a blank MIDI track and program some notes with mouse??
Sounds like you are recording something extra coming from Triton controllers.


opening this menu shows all recorded or programmed CC’s when there is a dot.

Yeah, that’s pretty much what I’ve done, and in an empty project. Yeah, I found it was CC73 if you read my second comment. Not sure why the Triton is sending this out and it’s getting recorded now in C14 when it’s never happened before.. in 20 years! (That’s how long I’ve used this synth with Cubase!) I actually thought my Triton had died of age but it works fine in C12.

When gear gets old, parts breakdown and can send wrong info.
Also, it’s possible battery problem in the synth after that long (I recently changed battery in my Kurzweil, pitch wheel acting funny among other things)

cheers
