AudioMidiSync Bugs

I'm working on some bugs that are related to AudioMidiSync:

1. Setting the Start Time to anything other than 0 caused the notes to burst emit.

2. Setting the speed to anything other than 1 caused weirdness with the notes being emitted.

3. Sliding the play slider backwards in play mode made "all the things" get out of sync.

I'm hoping to have this along with the new PianoRoll released before next year.
