Okay, help me out?

Before the house fire I was using straight midi for my professional set up. I would insert patch changes on the correct channels to trigger my harmony machine, synth etc.

Now that I'm starting all over with BIAB 2015, how would you advise me sitting up my new sound system? I assume you can't use the real tracks in midi and that I'll have to go with audio to take advantage of these great sounds?

How can I still trigger my external gear?

Thanks,

Allan
