I'm still midi deficient, but I'm getting stuff done... however, I'm having some strange issues... I'm building a percussion track in the Piano Roll view, and after some editing and moving things around, as you do to get them right, I have ended up with some drum sounds that are sounding, but don't seem to have a trigger... I'm looking at the track, for instance, there is only snare on the track, but 4 kick drum hits trigger whenever I hit play and I can't find them to delete them. In a couple of measures there are also a couple errant hi hat hits. I've check the properties on the other midi events in the same place on the track and they are assigned to the right notes... how do I find those rogue triggers and delete them? Any thought?

Event List should show them.

Try setting the length to 60 ticks for all hits and then as suggested above by Kalle check in the event list.

I should have said that, I guess, they do not show up in the Event List either, yet I still hear them in play. I'll try changing the length and see if that works.

Never mind, I guess, after rebooting my machine, the artifacts went away... very strange.
