Hi Guys

Thanks for replies, and sorry for slow response.

I tried setting bar 1 at first whole bar, ie skipping the upbeats, and this sounds fine in ACW window. All the bars come in spot on. Theres a grey bar marked 0 representing the upbeats, then off it goes on bar one.
BUT I still get a problem when i send to BIAB. The chord layout looks the same as it did in the ACW window, but without the upbeats bar. But when I play, the audio track start OK, but nothin happens on the chord screen for about 5 beats, so the chords screen is alwys 5 beats behind where it should be.
I've played around with this for ages - I cant see any other way of doing it. I'm also heartily sick of the track I was trying to play!!
Cheers
Tom
