Casio Cosmosunthesizer CZ-3000 User manual

OPERATION MANUAL
MANUAL DE OPERACION

Thank you for purchasing the Casio CZ-3000. The CZ-3000 is atotally digital
synthesizer under LSI (large scale integrated circuit) control, and is designed
using the same principles that apply to analog synthesizers, thus eliminating the
frequently heard complaint about digital synthesizers that they are too complex.
This makes the unit actually ahybrid that combines the operational ease of an
analog synthesizer with the tonal quality of adigital model.
3Modes of the CZ-3000 ~\
1NORMAL MODE
•Play of preset timbres.
•Modification of timbre data recalled From memory.
•Creation of new sounds.
•Application of various effects to timbres,
•Saving of timbres created to built-in memory or optional RAM cartridge
RA-3.
2TONE MIX MODE
•Mixing of any two timbres.
•Independent setting of each timbre level.
3KEY SPLIT MODE
•Splitting of the keyboard into UPPER and LOWER portions for independent
play of two timbres.
•Independent setting of each timbre level and effect.

PD (PHASE DISTORTION) SOUND SOURCE
The CZ-3000 employs aunique, CASIO developed PD (Phase Distortion) sound source
system. This system is capable of producing avariety of wave forms by distorting the read
phase angles of sine and cosine waves that are Written in ROM, The pattern ol the read
phase angle distortion is determined by the specification of the DCO (VCO of analog syn-
thesizer) WAVE FORM. The magnitude (modulation depth) of the read angle distortion
corresponds to the momentary value of the DCW (VCF of analog synthesizer) envelope.
(Fig. 1)

Fig, 1illustrates output of anon-
distorted cosine wave when aco-
sine wave in ROM is read with a

angle is read at acofisLmil speed
from through 2ir.
What would happen if we in-
crease the phase angle read
speed from through t and
decrease it from ir through 2t?
<Fig. 2)
As shown in Fig. 2, the phase
angle read is distorted rather
than linear, and the output co-
sine wave takes on what is close
to asaw-tooth pattern.
What would happen now if we
further increase the phase angle
read speed from through tt
and decrease it from xthrough
2t?
<Fig. 3)
Fig. 3 shows that the output co-
sine wave is almost aperfect
saw-tooth pattern.
PART 1NORMAL MODE

The revolutionary PD sound source system thus makes it possible to output waveforms
that differ from cosine waves by simply distorting the cosine (or sine) wave read from ROM,
Figs. "I through 3illustrate the patterns produced by increasing the phase angle read speed
from through it while decreasing the speed from it through 2x. This is the pattern effect-
ed when the SAWTOOTH waveform is selected in the DCO parameter.
Read phase angles are also distorted in accordance with the selection of the other DCO
parameter WAVE FORMs, thus making avariety of waveform outputs possible.
The magnitude of the read phase angle distortion corresponds to the momentary value
(change over time) of the DCW envelope. When the DCW envelope is set as shown in Fig.
4, an undistorted cosine wave is output at point (a), distortion reaches its peak at point
©, and asawtooth pattern as shown in Fig. 3is output. Distortion is reduced (modulation
become shallower) at point®, and apattern that is somewhere between acosine wave
and asaw-tooth wave as illustrated in Fig. 2is output.
When WAVE FORM is set to saw-tooth.

POINTS TO REMEMBER
1)The pattern of the read phase angle distortion corresponds to the WAVE FORM
setting of the DCO parameter.
2)The magnitude of the read output phase angle distortion (modulation depth) cor-
responds to the momentary value of the DCW envelope.
8-STEP ENVELOPES
The CZ-3000 features adual system DCO/DCW/DCA, and each system has its own indepen-
dent envelope generator for control of changes in notes, timbres and volume over time.
The envelope generators can set up to eight steps including setting of the sustain point
(the level at which anote is sustained while akey is depressed). This provides greater ver-
satility than the conventional ADSR generator and makes sound creation possibilities vir*
tually unlimited.

8-STEP ENVELOPES i

Fig. 1shows an example of an envelope employing 8steps. There are two attacks before
the sustain point, as well as athird attack after the key is released, resulting in an "after-
envelope".

time
Analog synthesizers usually require the setting of envelopes according to 4parameters:
Attack time, Decay time, Sustain level and Release time (hence, the name ADSR system).
With the envelope generator of the CZ-3000, only 3step settings are required to attain
the same effect.
BLOCK CONFIGURATION
The PD sound source of the CZ-3000 makes it afully digital synthesizer. Actually, however,
the DCO (pitch and basic waveform setting), DCW (timbre control), and DCA (volume con-
trol) digital circuits of the Parameter Section result in ablock configuration that closely
resembles an analog synthesizer. The block configuration of the CZ-3000 consists of LIME
1and LIME 2which make up adual system. DETUNE allows you to create differences
between the sounds generated by LINE 1and 2to produce subtle nuances. With LIME
SELECT, asingle line can be output or combined with the detuned line for atotal of 4
line output settings.

•VIBRATO is the parameter that oscillates the low frequencies of the DCO and applies avibrato
effect Another parameter applied to DCO is OCTAVE.
DCO (DIGITAL CONTROLLED OSCILLATOR)
DCO corresponds to the VCO of an analog synthesizer, and is comprised of WAVE FORM
for selection of the basic waveform and ENV (pitch envelope) for control of the pitch over
time for apressed key. The dual system line provides an independent DCO 1and DCO
2which can be used as desired.

•WAVE FORM Determines the basic waveform of a timbre. Independent settings can be made using the
DCO 1and DCO 2keys.
As can be seen in fig. a, there are eight types of basic waveforms: from SAWTOOTH
to RESONANCE 111. Any one of these eight waveforms can be combined as shown in fig,
bto produce atotal of 33 waveforms suitable for virtually any application.

•DCO ENVELOPE (PITCH ENVELOPE)
DCO controls changes in pitch over time. Independent envelopes can be set using the DCO

RATE/LEVEL NUMERIC VALUES
RATE
The RATE indicates the slope (interior angle in relation
to horizontal) of each step in the envelope. R-99 indi-
cates nearly 90° while R=indicates nearly 0°. Since
the value used is an absolute value, the slope increases
and decreases in direct proportion with the value of R,
regardless of whether the pattern shows arise or fall.
This means that asteep incline results In aquick level
change while agentle incline results in aslow level
change.
LEVEL
The LEVEL indicates up to what point each step rises
or falls (destination level), and the range is from 00
through 99, For the DCO envelope, LEVEL means the
pilch height, cind avalue of 00 is (hi: pilch of •: pressed
key. For the DCW envelope, L=99 results in abasic
waveform {see page 20 for details). For the DCA enve-
lope, LEVEL means the volume.

MOTES
•Even if the ENV STEP© key is pressed, it will be impossible to advance from the
present step if END POINT is specified. In this case, press the ENV POINT END
key again to cancel the END point and then press the ENV STEPS key. If an END
point is cancelled within STEP 1through 7, an END POINT is automatically desig-
nated in STEP 8and previously set data is automatically restored.
•The LEVEL for aSTEP that includes an END POINT is fixed as 00 and cannot be
changed.
•When aSUSTAIN POINT is designated in aSTEP. SUSTAIN POlNTs set in other
STEPs are cancelled.
iDCW (DIGITAL CONTROLLED WAVE)
DCW corresponds to the VCF of an analog synthesizer, and is comprised of KEY FOL-
LOW for control of the waveform corresponding to the keyboard range, and ENV (wave
envelope). The dual system line provides an independent DCO 1and DCO 2which can
be used as desired.
KEY FOLLOW/DCW
This parameter applies adifference change in the DCW envelope level in accordance with
the pitch of the key played, The DCW 1and DCW 2KEY FOLLOW keys are used to in-
dependently set each key follow.
Key follow can be set to levels ranging from through 9. The higher the note played,
the closer, the waveform comes to being asine (cosine) wave. (See Fig. 4.)
(Fig. 4)
Sine wave
The LCD appears as in Fig. 5when the DCW KEY FOLLOW key is pressed.

-MC— KEY FOLLOW
UE RANGE*!! (0s^9)
The VALUE keys in the Data Entry Section are used to set the RANGE value within a
range of through 9. The greater the RANGE value the greater the waveform level vari-
ance (timbre change rate) in the upper registers. Asetting of 9represents the maximum
variance.

DCW (WAVE) ENVELOPE
This parameter controls the timbre (waveform) change over time, and the DCW 1and
DCW 2EMV keys are used to independently set the timbre envelopes. The timbre enve-
lope is used to set the timbre (waveform) change over time for apressed key in accor-
dance with the RATE (slope) and LEVEL (destination level). Settings can be made to a
maximum of 8steps,

DCA (DIGITAL CONTROLLED AMPLIFIER)
DCA corresponds to the VCA of an analog synthesizer and independent volume enve-
lopes can be set using the DCA 1and DCA 2EMV keys,
KEY FOLLOW/DCA
This is the parameter that applies avariance to the DCA envelope 3n accordance with
the pitch of the key played. The DCW 1and DCW 2KEY FOLLOW keys are used to In-
dependently set each key follow.
The higher the note played, the shorter the time of the volume envelope,
