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/PORTA TIME)
Selects whether portamento is applied to the performance and species the
portamento time.
PORTA CRV
[ORG] button
Change according to the original curve
of the model.
[LINER] 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 DCO-1DCO-1
[TUNE] knob (OSC1 TUNE)
Adjusts the OSC1 pitch.
LFO (OSC1 LFO MOD)
Adjusts the depth to which LFO modulates OSC1.
ENV (OSC1 PIT ENV)
Adjusts the depth to which the ENV specied by OSC ENV
MODE aects the OSC1 pitch envelope.
[RANGE] button (OSC1 RANGE)
Species the octave of OSC1.
16’, 8’, 4', 2’
[WAVEFORM] button (OSC1WAVEFORM)
Selects the waveform that is the basis of the OSC1 sound.
SAW, PULSE, SQR, NOISE

3 DCO-2DCO-2
[TUNE] knob (OSC2 TUNE)
Adjusts the OSC2 pitch.
[FINE TUNE] knob (OSC2 FINE TUNE)
Finely adjusts the OSC2 pitch.
LFO (OSC2 LFO MOD)
Adjusts the depth to which the LFO modulates
OSC2.
ENV (OSC2 PIT ENV)
Adjusts the depth to which the ENV specied by
OSC ENV MODE aects the OSC2 pitch envelope.
[RANGE] button (OSC2 RANGE)
Species the octave of OSC2.
16’, 8’, 4’, 2’
[WAVEFORM] button (OSC2 WAVEFROM)
Selects the waveform that is the basis of the OSC2 sound.
SAW, PULSE, SQR, NOISE
[CROSS MOD] button (OSC2 MOD MODE)
Selects the MOD MODE type (OFF, SYNC, X-MOD).

4 MIXERMIXER
[DCO-1] knob (OSC1 LEVEL)
Adjusts the volume balance of OSC1.
[DCO-2] knob (OSC2 LEVEL)
Adjusts the volume balance of OSC2.
ENV (MIXER ENV DEPTH)
Adjusts the depth to which the envelope specied by
MIXER ENV MODE controls the OSC2 level.
[DYNAMICS] button (MIXER DYNAMICS)
Adjusts the sensitivity at which the velocity controls the
depth of MIXER ENV.
[MODE] button (MIXER ENV MODE)
Selects the envelope that is used as MIXER ENV.

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.
[CUTOFF 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 (RESOANCE)
Boosts the region of the lter’s cuto frequency.
Higher values produce a stronger result, giving the
sound a distinctively synthesizer-like character.
[HPF] button (HPF STEP)
Sets the high-pass lter’s cuto frequency in four steps.
LFO (FILTER MOD)
Adjusts the amount by which the LFO modulates the
cuto frequency.
ENV (FLT ENV DEPTH)
Adjusts the amount by which the envelope selected by the
MODE modulates the cuto frequency.
KEY F (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.
[DYNAMICS] button (FILTER DYNAMICS)
Adjusts the amount by which the envelope selected by the
[MODE] button aects the velocity.
[MODE] button (FLT ENV MODE)
Select the envelope and polarity used to control the lter.

6 VCAVCA
[LEVEL] knob (AMP LEVEL)
Adjusts the volume of the tone.
[MODE] button (AMP ENV MODE)
Selects whether the volume is controlled by ENVELOPE-2
(ENV2) or stays at a xed volume as long as the key is held
down (GATE).
[DYNAMICS] button (AMP DYNAMICS)
Adjusts the sensitivity at which velocity controls the AMP
ENV depth.

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

9 ENVELOPE-1ENVELOPE-1
KEY [FOLLOW] button (ENV1 KEY FOLLOW-S)
Species the ENV1 key follow in four levels. With higher values, ADR times become
longer as you play lower on the keyboard, and shorter as you play higher.
