I have a song that is all real tracks/real drums and I just spent some time using bar markers to set it all up.

It begins with acoustic guitar, then the bass comes in. Then drums, electric, and synth pad on the 1st chorus. On the second chorus a second electric comes in just hitting power chords. There is a long tag at the end with the string quartet overlaid and then the final two bar ending everything drops out except the string quartet.

I had it working perfectly. And played it through several times and saved my work regularly throughout.

I broke off for the time being and intended to come back later, open in Real Band and put in a long 8-bar crossfade in the tag and be finished.

When I open it now (still in BiaB) nothing plays. If I click around in the chord chart and start the song from different places, sometimes I can get a couple of the instruments to play. I've tried regenerating several times of course. At most only two of the real tracks will load. I think I confused it. Its definitely confusing me.
