I recorded some notes with a keyboard directly into Cubase.
Moved the MIDI to another track.
Left as is, the notes sound fine. When I change the Halion Instrument from Piano to Voice Ooh however, the notes sustain forever. They just run into one another until after a few notes there’s just a wall of sound.
I looked at the sustain info in the MIDI track and delete the info.
It got even worse after I did that.
