You can just use Real Band for it all, there's a lot of people here doing just that. It will generate music the same way as Biab. Usually I start in Biab and use Real Band afterward, but I have made songs only in RB. I got sent a song from another user in 7/4 time and found it was impossible to alter the style in Biab, but very simple in RB. The main reason I use Biab is auditioning styles, because you can hear the song faster. It plays while the song is generating, and RB plays afterward. I make a 4 or 8 bar 1 chorus test song and find a style suitable for use, and it will play almost immediately. Answers to any problems are found in search the forums, if you don't want to wait for a response. Best music forum on the web and company support too.
