Hi
For programming the CZ synths, you might want to look at the wonderful VirtualCZ. Its both a CZ VST emulator AND an editor for the physical synths..
btw, Im not sure how often the sales come along but, I got a 40% discount on the list price. I had the demo version installed and first got a 10% offer email, then 20% then finally 40% (which I jumped at!). Maybe the running the demo for a month or two triggers these offer emails??
