Hi, stevec. I've got a lot to say about this cymbal pack but I wanted to point out that you need to a) use the FXpansion License Manager to register the Z-Pack (which you've probably done) but then b) when you open your full version of Eco (not the DV version) rebuild your database. Then they should all be cool. Also I tried tossing some of the cymbals into the percussion slots in Eco and it worked fine. I'm shut down for the night but between replacing the ride/hi hat/crash/ride slots and then taking up the percussion slots you should have enough options to get that Z-Pack working very hard for you without a second instance. Cheers!
