I, too, strongly support midi. It might be considered "old" technology by some but the reason that it's stayed around so long is because it offers something that other things cannot. Maybe when electronics is enhanced sufficiently so that the end "sound box" that the midi commands drive has incredibly realistic sounds at a much more affordable price, the pendulum will swing back the other way.

Interestingly, I could feed midi input from BIAB into this electronic organ by Yamaha and get some pretty excellent output.

Or maybe Yamaha's Tyros 4 (which I'd just love to get my hands on and hook up to BIAB!)

Unfortunately the YouTube encoding has reduced the realism but I think you'll be able to hear what I mean.
