I'm pretty sure this is a bug. When playback of a midi track is stopped when the sustain pedal is depressed, even with the 'reset on stop' preference checked, the sound rings out. IE the sustain pedal stays depressed. IE the sound does not completely reset. This was true in prev. versions of Sonar and seems to continues in X3d. Stopping and starting again does reset the sound. But it doesn't work the first time. I think this may be an intermittent problem, but it seems to happen to me most of the time.
#2. Today I couldn't get cut and paste to work properly:
I was trying to cut and paste the looped clip entitled "4bar 105bpm" to a different place on track 15. No matter what I did it kept pasting to track 10 where that little white bar is. Saving and reloading fixed the problem, so it's no big deal but I'm wondering if anyone knows what was going on?
