Casio CZ-101 (1984)

 

Portable based on digital synthesis PD-Phase Distortion, strongly inspired by Yamaha FM technology.

pd synthesis waveforms

info KEYBOARD (weight: 3 Kg) 49 keys.
The main panel features a 16 x 2 lines display and 52 push buttons.
On the left side there is a single pitch wheel.

Terminal connectors:
- Midi interface (no Thru)
- cartridge slot
- line out
- headphones

acPower supply 6 X 1.5 V batteries or an external power supply type DC 9V negative in center. Original factory model is labeled AD-5.




editVOICE
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.


simulated resonance


edit PHASE DISTORTION process periodically distorts the phase angle of the oscillator altering the harmonic content, consequently creating new rich waveforms, 8 to be precise in the CZ series.
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).

simulated resonance

edit 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 combo.

playmodes 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
- line 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
- key transpose
- bender range


adsr ENEVELOPE
there are 3 EG 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 LFO
a single delayed amplitude modulator for DCA 1-2 at same time.
The LFO features variable depth and 4 waveforms:
-sine
-saw
-square
-ramp



midi MIDI
basic implementation but fully exclusive systems compliant for both edit and backup.
System compatible with Cz-1000.



memroy MEMORY
holds:
- 16 ROM sounds
- 16 RAM slots
- 16 RAM slots if card model Casio RA-3 is fitted.
RAM needs the internal 1.5V batteries to retain sounds (no lithium battery inside).

geek stuff


"especially good for digital noises and droning. The Casio Cz-101 is not the most powerful of CZ family but surely the cutest and most sought-after for its cheap 80' design with minikeys. "


"So if your fingers are fabulous on a keyboard but all thumbs when it comes to things electronic, get a CasioCZ-101. For a little money you could make it very big" - Casio AD
