The size of the Realtracks was huge. I've processed mine, but here's an example I dreamt up.

The old realtracks engine could only deal with say 10 bpm increments or 15. So you needed a file for 85, 100, 115, 130, 145 for say a guitar track.

The new engine can do with only 1 of those, so it goes through and deletes for you the files Pg music found redundant. The total size of the files goes down by 70 percent.

And to me they sound better.

Also some of the instruction and way they are used is 'fixed up'.

So you gain all around.
