Yes. It's not an arranger in the traditional sense (yet).

It'll just turn a lead sheet + .STY into a midi arrangement to begin with. That part is pretty much done. Next, I see if I can scale the arrangement's volume based on the melody(or whatever) you play live. I plan on starting the chord sequencer mid week. And I gotta find and set up some dang examples to explain this thing with in the next release. That's kind of holding me up more than I thought it would.

Keep in mind that PianoCheetah is freeware. I'm planning to sell it SOME day if enough people ever start using it. But not until then (if that ever happens).
