Casio CZ/ VZ/ FZ - Pro Series

Here's the post to the wind controller group that wasn't censored.
=============================================================

I have been lurking here for a few weeks, but there is much more
discussion than I can handle. It is of interest to me, but I just
don't have the time to devote to it.

I can tell you a little bit about the VZ-8M, having had the unit for
a couple of decades. Over the past year, a few VZ enthusasts have
breathed new life into it with some new patches--available at the CZ-
VZ Yahoo group. The new patches designed by users blow the factory
sounds away.

The VZ synth architecture is like a cross between the Yamaha DX (and
offspring) line and Casio's CZ line. The sounds are definitely bona
fide digitally controlled synth sounds. By today's standards it is
not a rompler with synth samples. For documentation on VZ
programming, see

The CZ/VZ uses iPD -- "interactive Phase Distortion." Basic
waveforms are read from ROM, but the sound shaping devices
(DCO/DCF/DCA on the CZ and the algorithms on the VZ) modify the way
basic wavform(s). Hence, iPD.

The VZ line allows you to create your own algorithm--the arrangement
of the oscilators. There are 8 oscilators per voice which can be set
up in different configurations (mix, ring modulation, and phase
modulation).

The VZ-8m does indeed have a special wind controller mode which
makes the synth engine more suited to wind controller performance.
Most notably, the sensitivity curve of aftertouch data for values 92-
99 are variations of an S curve. (More recent synths may also have S
curve data sensitivities.)

Hope this helps.
