This is a great product for (among other things) playing along in real time. What would make it better is if, instead of just sounds, it could (in real time) export Midi. For those of us with midi-compatible keyboards, etc., this would allow our midi-gadgets to use their own samples to generate sounds in real time.

Today, i generate midi files and play them through my keyboard while I play the piano part. This provides far superior drums and bass than what I can get with an mp3 file, etc. However, this is a static file (e.g, if I want to repeat the chorus another time, I can't -- or start in mid-song as an intro.) In addition, this lacks the visual output of iReal Pro where the current measure is highlighted. Therefore if I get behind a measure, it's a disaster.
