Cubase is setting CC7 to 0 in Kontakt 7&8, also SINE Player

Very weird. I had CarbonCopyCloner kick in whilst I was opening Cubase. So I killed CCC, but Cubase was still stuck so I had to force quit.

When I resumed I discovered that Kontakt instances (though not all of them) were not playing back, and if I opened the plugin window the volume control (CC7) was observed to drop to 0. Manually intervening would sometimes allow some notes to be played, sometimes they would still not play even with the volume up.

(Possibly other CCs, I think I saw CC32 changed)

I’ve fiddled with every Reset/Chase option I could find to no avail.

As well as manually drawing in CC7 with no effect!

I also reinstalled Kontakt but its fine both standalone and in at least one other DAW ( Reason 13 ).

I also deleted all my Cubase 15 Preferences from the ~Library/Preferences folder and let the app regenerate everything.

I’m completely baffled, and completely locked out of working. Help! (Hoping this is something silly and obvious)

Oh, I’ve been testing in a brand new empty file too to rule out project corruption.

Ok. I’m still checking, but it looks like the abort completely trashed my MIDI port mappings.

I’ve redone them all and things seem to be working now. I think it was the StreamDeck ports that were causing the issue.

Fingers crossed, this is the root cause…..
