Nicely done, Lugia.
Let me throw a penny into your dollar's worth of knowledge.
I own a Z3000. Would I buy another one... no. Do I like it yes.
BUT.... one thing I learned after some wiggle-time, is that I like being able to switch octaves on the fly (usually measured in 'feet' from the old pipe organ standard). When blending two oscillators, there's value in being able to try an oscillator at a different octave instantly and then being able to go back. It's also nice when performing to switch an octave for variation.
The Z3000 only offers sweepable control of your pitch. So it's not a possibility to do this. If I had to do it over again, I'd probably go with an Intellijel Dixie II+.
Though, come to find out the original poster already has his two Z3000s. How do you like them, Pauly?
