I bought EZD2 this morning and installed it. I only had about 45 min. To play with it before the wifey got up...that kind of ended my adventure for the morning.
So far though, I like a lot of the upgrades. I think the DW Kit sounds pretty good. I would say good enough that I might not want to flip it to AD after creating my song midi structure. I, of course, won't know until I have a new song in the works and many of the instruments tracked to see how it sits in the mix. Soloing it up though, not bad at all. I flipped through some of the individual kit choices and have already discovered which pieces by themselves I prefer. I have always really liked the cymbal, ride and hats sounds that come out of EZD. Toms sounded really good. Snare had nice punchy tones. The kick has always been my biggest issue with EZD, in that it always had more of a beater tone to it and less thump or bass tone. The kick seemed much improved to me.
I did the tap tempo test right away and that is going to be really handy. I had no trouble with the tempo sinc'ing with the temp set on my song template; since to host worked great.
