We're talking Biab here. A biab song is already midi. That's what John's talking about. You only worry about recording your live midi playing if you're recording your own melody or solo track. As John says I usually don't have to bother recording a midi melody because I can find it on the net somewhere as a midi file and just import it.
Real Band or another sequencer is a different thing. You could easily use a midi keyboard/guitar/wind controller to record all kinds of different parts into a multitrack program.
