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.

Envelope

You can edit the ADSR settings of the envelope.

[A] knob (ENV1 ATTACK)

Adjusts the Attack time.

[D] knob (ENV1 DECAY)

Adjusts the Decay time.

[S] knob (ENV1 SUSTAIN)

Adjusts the Sustain level.

[R] knob (ENV1 RELEASE)

Adjusts the Release time.

8 DYNAMICSDYNAMICS

[DYNAMICS] button (PITCH DYNAMICS)

Adjusts the sensitivity at which the velocity controls the

depth of the pitch envelope.

[MODE] button (OSC ENV MODE)

Selects the envelope and polarity used to control OSC.
