Casio CZ/ VZ/ FZ - Pro Series

Jim are you using a PC based editor for the VZ? That helps a lot. There are
tons and tons of programming options on the VZ, easily enough to fill a few
PC screens with controls. The thing about the VZ is that it doesn't have a
filter so the only ways that you have to control harmonic content is either
through the addition of the basic waveforms (sine, noise1 , noise2 and saw
1~saw 5) , ring modulation or phase distortion. To do additive all you need
to do is select the waveform that you want for each osc and then set all the
oscs to mix. For ring mod and phase distortion you will always be working in
pairs of oscs. Then what's really cool is that you can then have each pair
(you'll have 4 pairs, 8 oscs total per patch)  ring mod or phase distort the
next pair in the chain.  One thing to remember is that you're basically
controlling the harmonic characteristics of the sound by manipulating the
volume of individual components. Unfortunately that's about the only
intuitive programming advice I can give. Doing additive synthesis on the VZ
is the most straightforward after you've figured out the relationship
between the VZ levels and real volume. Ring Mod and phase distortion are
more of a guessing/experimentation game, one thing to note though is that
the more iterations of modulation you have going on, the "nastier" the sound
will be. Once you've chained a couple of oscs together get ready for some
seriously distorted tones.  I always thought that the VZ was a pretty
fascinating instrument and that its very fun to program (I use Unisyn for PC
right now).

	hi- just picked up a VZ8M, I was curious ... and not disappointed
either.
	Lots of potential nastiness of course after all it is an early
digital synth
	but also lots of really nice warmth and some phat corky/raspy stuff,
one
	patch is called 'PPG sync' and its justified!- I've had CZs in the
past
	(which I think are great) and this box is pretty different.  I got a
disk
	full of patches, anyone interested? I'm posting to ask if anyone has
any
	resources with regard to programming it- kind of how to think
through the
	signal path- some coherence.  Mmm, er ... ok so you have a chain of
	modulators (like DX synths) but beyond this?
