That's very kind of you Matt.

I've just made a very simple and basic 12 bars where the same thing is happening. This is in 3/4 timing. I have tried a sample in 4/4 timing and with different RealTracks with the same result.

Anyway, here's a link to my basic 12 bar sample file.

Hope you can find what's wrong.

Thanks
