Mac the problem with using Sonar is I loose the lyrics funtion. I send the lyrics screen to a small monitor in front of my singers and another feed to a video projector for the congregation. I will also send a feed of the chord screen to any guitar player or piano player. I play both so I Have my real-time chart playing along with the song...It could be beautiful...if I could have it reliable. I was using Sound Forge in the past using a stereo WAV file. I would set my markers and trigger it with a midi keyboard and have control over the flow of the song that way. But I would use tracks from different companies, with different musicians, volumes etc, and it had no continuity. BIAB/RB would be a boon to the small church-music department if it wasn't so tempramental.
Thanks
