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.
