I'm very interested to see exactly what this implementation of MPEX actually is.
If you look at the Cakewalk stuff closely, you will notice that they never actually mention MPEX2, only as "MPEX" -- don't know if means we get the older revision or if it is just marketing short-hand. Additionally, all the cakewalk stuff talks about MPEX Time-stretching, not time/pitch stretching and no pitch correction points at all.
I am guessing here, but I reckon that the time-stretching stuff is licensed and implemented into track view et. al., so as to facilitate the "Nudge" features. I think that they have not licensed the full pitch correction stuff, otherwise they would have made more of a song and dance about it. I am guessing that the only pitch correction stuff will be implemented at the semi-tone/tone level in the loop construction window -- not as an in-built replacement for something like Antares Auto-Tune.... And I can't always afford 'The Dachays' to do my backups!!
So said, I have spent the last year editting thirteen songs into "real" shape. This stuff is going to save me a lot of time and I can't wait to get my dirty little hands upon it.
Ciao,
