Casio VZ-10M User Manual

the VZ-10M's amazing sound synthesis capabilities is an
IPD” (interactive Phase Distortion) sound source. In order to
‘most out of your VZ-10M, itis vitally important that you under-
‘at least the basic theory behind this new sound source.
‘module
contains
a
DCO and
a
DCA,
and
is
capable
of
generating
it waveforms.
(D) If you're
familiar
with analog
synthesis,
you
of the modules
as oscillators
with controls.
Inthe
IPD system,
‘generated
by any module
can be used in either
of two
ways;
1 ~ to produce audible sounds
2.- to modify waves generated by other modules
speaking, the 8 sound source modules work in associated pairs
‘called “Internal Lines,” or simply “lines.” There are 4 internal
B, C and D, as shown to the right. (2)
forms generated by both modules in any line can be used together
different ways. The waveforms can be mixed, or one of the wave-
scan be used to modulate the other for RING modulation or PHASE,
red at the right. (@)
hhow the modules in each line are interrelated, let's analyze the
between the two modules which make up LINE A.
‘consists of two different modules - Ml and M2. While these mod-
entirely independent and generate totally independent waveforms,
bbe utilized together in any of three different output formats -
‘output), RING (ring modulation) and PHASE (phase).
WAVEFORM OUTPUT
MIX is selected, the waveforms generated by M1 and M2 are out-
according to the formula given below. (®)
‘MIX: MI + M2
ook a bit complex at first, but it's really not. It may be easiest
‘of MI and M2 as individual oscillators (which they are). In the
format, both of these oscillators sound together.
MODULATION
two waveforms can also be output using RING MODULA-
Which is created according to the formula shown below. ())
RING MOD: M2 + M2 x MI
probably heard ring modulation - even if you don’t recognize the
_ Typically, it creates a “clangorous” or metallic sound and is often
“synthesizing gongs, bells and other ringing percussive sounds.
