Thanks MountainSide...

I have a question already.

I've done a test song layout and saved the file
I noticed after selecting 'associate files with BIAB' the files have their proprietary file extensions.

Can I import this file into Cakewalk (Sonar 5.0PE) and work with it further to track vocals.
I was thinking it's still a midi file?

Many thanks to this think tank.

Carry on...
