Any advice for one hanging note -C5 - when key is pushed on MIDI controller?

I have an issue that seems to have started randomly on Cubase 10.

If I’m playing my controller (which is an OB-6), the C5 note hangs because Cubase is not detecting a Note Off command.

Here is what I see on the MIDI Monitor Insert:

It is not related to the physical key on the controller, because if I change the octave on the OB-6, the hanging C5 note can be triggered from different keys.

It also happens if I attempt to control an external desktop synth via Cubase, using OB-6 in and out to the desktop synth.

If I open a standalone VST, it behaves normally. If I use the keys on a VST, or a note in piano roll, it works fine.


Let me know if you have any ideas. Thanks!

Hi,

That sounds weird.

Could you try in Cubase Safe Start Mode, please?

The issue is not present in Cubase Safe Mode.

EDIT: I deleted the following files and the problem went away:

C:\Users_username_\AppData\Roaming\Steinberg\Cubase 10_64

Defaults.xml
RAMpresets.xml


Thanks for leading me down the right track.
