I am a songwriter that uses Logic Pro 9.1.8 as my main DAW on a MAC Pro Dual (2.66) processor, 12-core with 32 gig of ram. I also have more plug-in virtual instruments and processors than one can actually use and have a library of over 20,000 Apple Loops. As I stated I am a songwriter/producer who is mainly a vocalist/guitar player. There are frequent occassions when I work alone in my studio and other session players (keyboards, etc.) are not available to lay down tracks for my song demos. This is the main reason I I am looking into BIAB 12.5 (or 13 when it is available for MAC) to provide me with built in session players that are ALWAYS available, 24/7. My main concern however, is as follows: Can BIAB audio and MIDI tracks be transfered into audio and MIDI tracks in Logic Pro 9.1.8. If YES, what is the degree of difficulty in accomplishing this? The answer to this is critical to my decision regarding purchasing BIAB 12.5 (or 13 when available) to use in my studio set up.
