This one's really got me stumped. Here's what I did: imported a stereo audio file to track one so that I could listen to the song and add several tracks of midi on tracks 2 and below. After importing I ran it through the ACW, set the time signature to 6/8, then manually set the tempo hitting f8 at the beginning of each bar. Sent that to RB and started creating midi tracks that mimicked those on the track 1 audio.

All was going fine. Then I noticed that for some reason if I started playback from any measure after measure 12 the audio on track 1 would cease to sound (no movement on it's meter either). Only the midi tracks below it would sound. But if I started playback from any measure 1 through 12 and let it run, all tracks would sound, including the audio track, to the end of the song. Try to play back from measure 13 or beyond and I only get sound from the midi tracks. Start playback from any measure 1 through 12 and audio on track 1 would also sound, as long as I did not hit stop. Looked at the piano roll view (and audio view for track one) between measures 12 and 13 to see if there were any inadvertent controller commands hanging out but saw nothing. All the audio data is visibly there on track 1.

Anyone have any ideas on this?
