During playback some instruments continue to sound their last note even when there's a rest in the next bar. There's no pattern or consistency. Sometimes it's one instrument and sometimes an entire section.

Also, at a slow tempo of quarter = 72, I have 16th note trumpet pulses with each player on one note and even with applied staccato articulations, there's no separation between the notes and sound like whole notes.
