Ableton piano roll selection imput makes infinite sound

When I select notes with the plugin start making noise as it should, but it doesn’t stop until you play your midi file again. This is very annoying when trying to create a melody or whatever.

I am unable to reproduce this, how exactly are you achieving this?

Perhaps your midi controller is sending out bad midi messages.

My M-Audio Code 49 has a habit of doing this.

No, it’s Ableton’s piano roll itself.
