Thank you! I have another month of BIAB under my belt since I made this post. I have found that I usually don't do an entire backing track in BIAB. I do some of it, then save as .wav, put it up in Audacity and add more tracks. I see that it's possible to render the song as all separate audio tracks. I need to get that figured out too! That would make for a more flexible final mix.

I haven't had time to really try Real Band as yet. It sounds like that is where I should be spending my time. I'll give it a go as time permits.

Thanks again!
