Midi notes sustain forever

Howdy.

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.

Any ideas?

How do those notes look in the MIDI Key Editor? (the piano might just be sounding o.k. because the notes are decaying naturally anyways, even though they too are in fact still playing).

I drew a new section and copied the notes over. Worked ok after that. Kinda weird actually.
