This document explains about the parameters and setting screens for the ZENOLOGY Pro
Model Expansion.
The parameter names, the order in which they appear and other information may dier,
depending on the product.

1 SystemSystem
CONDITION
Simulates the changes that occur as a unit ages.
PITCH DRIFT
Adjusts the slight pitch drift that occurs when notes are
played on an analog synthesizer.
KEY MODE
[SOLO] button
Sound is produced monophonically.
[POLY] button
Sound is produced polyphonically.
[UNISON] button
Sound is produced in unison.
[SL-UNISON] button
Sound is produced in monophonic unison.
PORTAMENTO [OFF] [ON] button
PORTA MODE
Selects whether portamento is applied to the performance.
PORTA TIME
Species the portamento time.
PORTA CRV
[ORIG] button
Change according to the original
curve of the model.
[LIN] button
Change in a linear curve.
[EXP-1] button
Change in a non-linear curve (gentle
slope).
[EXP-2] button
Change in a non-linear curve (steep
slope).
[PRM EXP] button
(PARAM EXPANSION)
If this is ON, the range of the LFO
RATE, CUTOFF, RESONANCE, and
FILTER ENV DEPTH parameters are
extended beyond the range of the
original model.

2 VCO-1VCO-1
[CROSS MOD] knob
Uses the OSC2 waveform to change
the frequency of OSC1. Higher values
cause the sound of OSC1 to be more
complex, allowing you to create
metallic sounds or sound eects.
[RANGE] knob (OSC1 RANGE)
Species the octave of OSC1.
16’, 8’, 4’, 2’
[WAVE FORM] knob
(OSC1 WAVE FORM)
Selects the waveform that is the basis
of the OSC1 sound.
TRI, SAW, PW, SQR

3 VCO-2VCO-2
[SYNC] button (SYNC SWITCH)
This is oscillator sync. It produces
a complex waveform by forcibly
resetting OSC1 to the beginning of
its cycle in synchronization with the
cycle of OSC2.
[FINE TUNE] knob
(OSC2 FINE TUNE)
Species a ne adjustment to the
pitch of OSC2.
OSC2 MODE NORAML/LOW FREQ
NORMAL
OSC2 operates as NORMAL
(audible frequency range).
Use the [RANGE] (OSC2 RANGE)
knob to set the frequency.
-12–+24
LOW FREQ
OSC2 operates as LFO (low
frequency range).
Use the [LOW FREQ] knob to set
the frequency. 0–127
[WAVE FORM] knob
(OSC2 WAVE FORM)
Selects the waveform that is the
basis of the OSC2 sound.
SINE, SAW, PW, NOISE

4 MIXERMIXER
[VCO-1] knob (OSC1 LEVEL)
Adjusts the volume balance of OSC1.
[VCO-2] knob (OSC2 LEVEL)
Adjusts the volume balance of OSC2.

5 VCFVCF
[R] [M] [S] buttons
(VINTAGE FLT TYPE)
If a vintage type model is selected,
these buttons change the type
of lter.
[R] models a Roland lter, and [M]
and [S] model vintage synthesizers
made by other companies.
[HPF] knob
Adjusts the cuto frequency of the
high-pass lter.
[FREQ] knob (CUTOFF)
Species the cuto frequency of
the low-pass lter. The frequency
region above the cuto frequency is
cut, producing a more mellow tonal
character.
[RES] knob (RESONANCE)
Boosts the region of the lter’s cuto
frequency. Higher values produce a
stronger result, giving the sound a
distinctively synthesizer-like character.
SLOPE (FILTER SLOPE)
Selects the type of slope for the low-pass lter.
-12dB/OCT, -24dB/OCT
[ENV-1] [ENV-2] buttons (FLT ENV MODE)
Selects the envelope that is used to control the ENV-1/
ENV-2 cuto frequency.
ENV MOD (FLT ENV DEPTH)
Adjusts the amount by which the cuto frequency is
controlled by the envelope.
FILTER MOD
Adjusts the amount by which the LFO modulates the
cuto frequency.
KEY FOLLOW (FLT KEY FOLLOW)
Adjusts the amount by which the keyboard pitch aects
the cuto frequency (key follow). With smaller values, the
cuto frequency becomes lower as you play higher notes.

6 VCAVCA
[LEVEL] knob (AMP LEVEL)
Adjusts the volume of the tone.
LFO MOD (AMP MOD STEP)
Uses the LFO to vary the AMP volume (tremolo eect).
Higher values produce a greater eect.

7 LFOLFO
WAVEFORM (LFO WAVEFORM)
Selects the waveform of the LFO.
SINE, SAW-DW, SQR, S&H
RATE (LFO RATE)
Species the rate of the LFO cycle.
DELAY TIME (LFO DELAY TIME)
Adjusts the time from when the key is pressed until the
LFO starts to apply modulation.

8 VCO MODULATORVCO MODULATOR
LFO MOD
Adjusts the depth at which the LFO
modulates the OSC.
ENV MOD (PIT ENV DEPTH)
Adjusts the depth at which the LFO
modulates the ENV1.
FREQ MOD (DEST SELECT)
Selects the OSC that is modulated
by LFO MOD.
Select buttons (PW MODE)
Species the pulse width mode.
LFO : The pulse width is changed
by the LFO.
MANUAL: The pulse width is changed
by the PULSE WIDTH MOD.
ENV : The pulse width is changed by
the ENV1.
Slider (PULSE WIDTH MOD)
Adjusts the amount of pulse width
change.
