That would be "Digital Performer", a MIDI sequencer with digital audio. THe
speed/pitch shifting technology is called "PureDSP". Mac only, I think.
I got the demo CD too; it is pretty impressive. I *don't* know if it works in
"real" time (i.e. can stretch in time more or less equal to the length of the
piece you're stretching) or not.
Mark of the Unicorn has been in the MIDI/Sound/Music business longer than most
and has some pretty decent stuff. People interested can check out
