This is a great gift; I noticed the files in my user area a week or two ago and downloaded them, but it seemed the samples were the same so I was already pretty sure the difference was in the programming.
I have been recommending these to people for years, hoping they'd come up for actual sale.
The only problem I had with the original set was that it was difficult to get usable volume without adding gain -- and this is coming from someone who typically records at -24 dB down from full scale!
I haven't had a chance to use the new matrices/presets/etc. yet, as I'm in the middle of moving from an apartment to a house (where I can set up a proper studio -- yay!).
