Halion 6 Notes sticking in midi editor since update.

Since the Cubase Pro 10.0.20 update, instruments in Halion 6 stick when i click on the drawn or played notes in the full midi editor (piano roll). Notes played from my keyboard release fine, as do notes played if i click the piano roll itself to play notes. I need to play the note from my keyboard to turn it off, or do a Midi Reset from the Midi Menu. Any ideas? None of my other VST’s are affected, it’s just Halion 6


Make sure your HALion is up-to-date. You can try to change the Buffer Size (and maybe then back). You can also try to trash HALion preferences.

Thank you Martin, good tip! *My issue SOLVED by updating the latest version of Halion 6 via Steinberg Download Assistant.
