I got SSD because I was also unhappy without the ability to tweak within EZD2. I opened it up once, played around with it for 10 minutes, closed it and bought SD3.
I know it’s a big price difference, but man, I couldn’t be happier with SD3 and I haven’t even bought an expansion pack for it yet. I mainly wanted to print the individual drums to tracks into Logic so I could tweak the EQ in there, but EZD didn’t allow that. With SD3, I don’t even need to, the mixer section is great and provides all I need there. You can turn everything off and start fresh if you want. There’s aux tracks and everything on there.
You can also stack drums, so if you’re pressed between two snares, you can actually use two different snares (or any other drum) together.
The UI is a breeze after working with EZD2. There’s also another awesome feature, you can drop an audio file of a drum track into it and it’ll separate all the drums for you into MIDI. I haven’t used that yet, but that’s pretty damn cool.
I also have GGD, I’m not sure which pack, but it has the Reptile kit in it. I love the drum sounds on the last Periphery album and while the samples were great, Kontakt gave me a bunch of issues and I just gave up. I also had trouble getting the MIDI mapping to line up with previous MIDI files I made, despite what setting I had it on.
If you bought EZD2, you get like a $50 discount for the crossgrade, I think it ended up costing me $350. While I’m not broke, that was still a good size investment, (considering I bought a 50’s Classic Strat for $300....) but I have ZERO regrets about it.
