Software arrangers?

[phatt]

Does anyone know about "Callisto"?
It looks like a software auto Acc keyboard idea, all done on the computer.
I bit of info here;

It's a dead end.
Wondering has anyone used this?
If it works it would be interesting as it would mean one could use any midi keyboard to trigger styles. Well I'm assuming that IS what it does?
Thanks, Phil
