I'm using BIAB 2011 on a new Windows 7 machine (notebook) along with SONAR X1. I have a song based on one of the BIAB demos (jazz brushes) for which drums are the only real instrument (RealDrums). In BIAB, playback is fine, drums (audio) and other tracks (bass, piano, etc. - BIAB/MIDI) are completely in sync. I save the song (.MGU) and also export it to standard MIDI. Open the all-MIDI file in SONAR, playback is fine, as usual. Then I import the audio (.WAV) track automatically created by BIAB into a new audio track in SONAR, lined up at the first measure. The playback of the drums (audio) and the MIDI tracks are out of sync by a fraction of a second - not sure exactly how much, but audibly and unusably so. I have tried manually shifting the audio track to line up with the MIDI and have never succeeded.

I searched for "latency" here and I read somewhere that there is a setting for adjusting latency between audio and MIDI rendering, which I assume is for playback in BIAB. But there everything is fine (I think something was set when I installed on this PC, an audio setup step that presumably sets this based on a test). Is there anything you have to do to export real audio and MIDI tracks so they will line up when imported to a DAW such as SONAR?

A possible workaround might be to render the MIDI tracks to audio in BIAB (I think I have done that - I've been away from recording for a couple of years). But I really want to render the MIDI tracks using the various soft synths in SONAR, so I really need the MIDI and RealDrums to line up.

Thanks,
