Thank you again for your replies! They have been very helpful.
Yes, I have looked at some of the demos and with my Korg Workstation I believe I can make it work to my style of music, as if I read it correctly BIAB can be used with other DAWs like Garageband to mix things together. I am not expecting BIAB to be able to give me a whole song by itself, but we'll see on some of them. I have found some interesting and possibly useful sounds on demos of some of the music tracks.
Basically I am looking to give my songs a fuller sound that I haven't been able to do with just my Korg despite all of its features.
