VOICE system manages 8 digital voices based on PD synthesis.
A basic patch is composed by 1 or 2 DCO or LINES which are detunable digital sinewave-cosine oscillators processed by logic mathematical operations. DCO LINES can be
mixed with noise (no gain) or ringmodulated together with fixed depth.
PHASE DISTORTION process periodically distorts the phase angle of the oscillator altering the harmonic content, consequently creating new rich waveforms (8 to be precise).
The pattern of the distorted reading phase angle determines the DCO, while the amount of distortion of the reading phase angle (the depth) is determined by a dedicated EG DCW (digitally controlled wave) which transforms the harmonics from pure sine to full distorted wave (99 stepped values).
WAVES each DCO is composed by 1 or 2 rich waves out of the 8 available.
The second wave follows the first one
for each periodic cycle, thus creating even more waveforms. However there are some hardware restriction: it it not possible to mix 2 waves from group 2; following this rule, it is possible to obtain 33 different combinations.
PERFORMANCE the 2 DCO lines can be set to 4 different path modes:
- line 1: just DCO1, 8 voices polyphony
- line 2: just DCO2, 8 voices polyphony
1+2: DCO1 + DCO2, 4 voices polyphony with detune
- line 1+1: stacks 2 times DCO1, 4 voices polyphony with detune
In addition there are are some playmode functions:
- portamento time
- monophonic mode
- bender range
ENEVELOPE 3 EGs for each line DCO (6 in total):
- DCW PD: 8-stages + 8 levels + 8 sustain points that determines the level at which a sound is held as long as a key is pressed
- DCO pitch: same structure as DCW
- DCA amplitude: same structure as DCW
LFO a single delayed amplitude modulator for DCA 1-2 at same time.
features variable depth and 4 waveforms: sine, saw, square and ramp
MIDI basic implementation but fully exclusive systems compliant for both edit and backup.
System is fully compatible with Cz-1000 model.
16 ROM sounds
16 RAM slots
- 16 RAM extra slots if card model Casio RA-3 is fitted.
RAM needs the internal 1.5V batteries to retain sounds (no lithium battery inside).
EDITORS some computer-based softwares:
Czrider (atari ST) PIC
soundquest ($ mac / pc)
Casio CZ-101 Patch Editor (max/msp IOS)
Soundiver (out of business).
- lithium battery for volatile memory
- DISPLAY LCD replacement VIDEO
- circuit bending
|CZ-1000: the same but bigger and normal keys plus membrane buttons
cz-3000: 16 voices 1 DCO or 8 voices 2x stacking 61 keys and chorus effect
cz-2000S: same as 3000 plus internal stereo speakers (also known as 2600s for other market)
cz-230S: tiny as cz101 but preset non editable + speakers + PCM drums
cz-5000: with (difficult) sequencer and 61 keys
cz-1: the biggest with keys velocity with Aftertouch (no sequencer)
