Preset Group, see page 14 “Editing the Perfor-

mance Control Functions”, and if it is the one in

the Memory Group, see page 17 “6. Edit”.

* The depth of the Modulation can be changed as

shown on page 14 “Editing the Performance

Control Functions”.

To turn Portamento off:

Push the Portamento Button @

again.

The indicator goes out.

* The time needed for a sound to move from a

pitch to another (Portamento time) can be

e How to record Chord Data used for Chord Memory Function

When a chord data is recorded into the a JUNO

with the Memory Protect Switch set to the ON

position, it is erased by power off. If you wish to

retain the recorded chord data even after power

off, you should record it with the Memory Protect

Switch @ set to the OFF position.

<OPERATION>

@ Set the Memory Protect Switch as shown

below.

ON OFF ON

Memory Protect Switch ®: ON —

Erased when the power is off.

ON OFF ON

im Memory Protect Switch @: OFF — Retained even after the power is off.

@ Press the Write Button ® while holding

the Chord Memory Button © down.

The Display @® will respond with:

@ Play the chord you wish to record.

When all the keys are released, the chord data is

recorded, and the Display @ will respond with:

When the Memory Protect

Switch is set to ON.

When the Memory Protect

Switch is set to OFF.

@ If necessary, return the Memory Protect Switch to the ON position.

* While a chord data is being recorded, the Octave

Transpose or Key Transpose function does not

work, therefore, the middle C key always works

as C4 key.

* When the recorded chord is being played, the

Octave Transpose and Key Transpose functions

work. When Octave Transpose is normal and

the Key Transpose is 0, playing the C4 key will

faithfully recall the recorded chord.

* By recording the C4 key, the a JUNO can be

played as a monophonic keyboard.

* If the keyboard is being played extremely fast

or too many NOTE ON messages are continu- ously sent into the MIDI IN, the chords may not

properly sound.

e. Key Transpose

The keyboard can be transposed to any key you

like within + an octave (—12 to +12 value). There-

fore, you can play music in various keys without

using different keys.

How to Transpose

1. Using the « Dial @

@ Push the Key Transpose Button@.

As shown in the picture, each time you push the

Tune/Function Button @, the function shown in

the Display changes.

@ Using the a Dial, change the value of the function to your taste.

1. Tuning

Example V

This function is used to tune with other instru-

ment. The pitch of Ad key can be set to 430 to

454 Hz.

The Display @ shows the pitch currently set, and if

“p>” mark is shown on the left of the Display, the

actual pitch of the a JUNO is slightly lower than

the set pitch shown in the Display. If “<4” mark is

shown on the right side of the Display, the pitch is

higher. When both “P” and “<4” marks are

shown at the both ends of the Display, tuning is

done.

2. Modulation Sensitivity

Example V When the Pitch Bender/Modulation Lever @ con-

trols the Modulation effect, this function deter-

mines the depth of the Modulation effect from 0 to

127.

3. Portamento Time

Example V When the Portamento effect is on, this function

sets the time needed for the slide of the pitch from

one note to another.

* At0, no portamento effect is obtained, and 127 is

the longest time.

4. Preset Tone Colors’ DCO Pitch Bender Range

Example ¥

When the Pitch Bender/Modulation lever controls

the Pitch Bender effect of the whole preset tone

colors (P-11 to 88), this sets the depth of the effect

from 0 to.12.{1. represents semi-tone).

5. Pedal Switch

Example ¥

7. Tone Color Parameters

A tone color consists of various parameters, there-

fore, to edit a tone color, change the values of

those parameters.

a. Synthesizer Structure

The a JUNO’s synthesizer section consists of

several blocks as shown in the picture. Each

block of the synthesizer section is controlled by

relevant tone-color parameters.

® DCO Block

Modulation Pitch

Lever Bender

© LFO Block

@ DCO (Digitally Controlled Oscillator)

DCO is the digitally controlled oscillator that con-

trols the pitch and generates the waveforms that

are the sound source of the synthesizer.

@® HPF (High Pass Filter) The HPF (High-Pass Filter) is a filter that passes

high frequency harmonics and cuts off the lower

ones. This changes the waveform and controls the

tone color.

@ VCF (Voltage Controlled Filter)

Each VCF lets lower frequency harmonics of the

input signal pass and cuts off the higher ones. In

other words, it is a usual low pass filter. By con-

trolling the cutoff point and resonance, the

waveform changes, thereby the tone color alters.

R @ 1G) VCF Block VCA Block

Keyboard

mae Audio Signal

-— Control Signal

@ VCA (Voltage Controlled Amplifier)

After filtered in the VCF, the signal is fed to the

VCA where the volume (amplitude) of the sound is

controlled.

@® CHORUS

@© LFO (Low Frequency Oscillator)

This oscillator generates extremely low frequency,

so produces a vibrato or growl effect by control-

ling the DCO or VCF.

@ ENV (Envelope Generator)

This generates the control voltage (Envelope)

which controls the DCO, VCF and VCA, therefore,

alters the pitch, tone color and volume in each

note.

b. Parameters

DCO (Digitally Controlled Oscillator)

When the LFO is controlling the pitch of the DCO,

this adjusts the depth of the vibrato effect in the

range of 0 to 127.

When the ENV is controlling the pitch of the DCO,

this parameter sets the depth of the modulation in

the range of the 0 to 127.

oO DCO Pulse Waveform

Example V

Pulse wave is selected.

This parameter determines the depth of the vibrato

effect when it is controlled by aftertouch. 0 to 15

are valid for this parameter.

This sets the maximum effect of the Pitch Bender

caused by moving the Pitch Bender/Modulaion

lever. 0 to 12 are valid for this parameter, and 1 is

semi-tone, therefore, 12 is an octave.

Display Waveform Spectrum

See page 21 “DCO PW/PWM Depth”

* The pulse width of 03 can be set at DCO PW/PWM

Depth.

© DCO Sawtooth Waveform

Example V

Sawtooth waveform is selected.

See page 21 “DCO PW/PWM Depth”

* The pulse width of 03 can be set at DCO PW/PWM Depth.

DCO Sub Oscillator Waveform

Example V

This selects the waveform of the Sub Oscillator

that generates the pitch 1 or 2 octaves lower than

the pulse wave or sawtooth wave.

O DCO Sub Oscillator Level

Example ¥

This sets the volume of the Sub Oscillator from 0

to 3. At 0, there is no oscillation.

O DCO Noise Level

Example V

This sets the volume of the Noise which is often

used for wind or surf. 0 to 3 are valid, and at 0,

there is no Noise generated.

o DCO PW/PWM Depth

Example ¥

| urseos zn | SAWTOOTH

This parameter works only on the Pulse Wave 03

and Sawtooth Wave 03. The pulse width of a wave

can be determined by the value from 0 to 127.

21

co DCO PWM Rate

Example V

This parameter works only on the Pulse Wave 03

and Sawtooth Wave 03. The rate of the LFO mod-

ulation that changes the pulse width of the

om waveform can be set. 0 to 127 are the values valid

for this parameter. At 0, however, the pulse width

is not modulated by the LFO but set at the PW/

PWM Depth. When this parameter is set to the

value other than 0, the pulse width set with the

DCO PW/PWM Depth is the widest pulse made by

L the LFO modulation.

HPF (High Pass Filter)

QO HPF Cutoff Frequency

O VCF ENV Depth

Example ¥ This parameter controls the cutoff point of the VCF

in each note with the ENV curve set in the ENV

section. As you increase the value, tone color

within one note changes more drastically. 0 to 127

are valid for this parameter.

VCF ENV Mode

Example V This is to select the polarity of the Envelope curve

that controls the cutoff point of the VCF. Usually,

ENV serves to decrease the VCF's cutoff point.

Normal with Dynamics

The ENV with Dynamics serves to increase the VCF’s cutoff point.

This modeisrather special; the ENV has nothing to do with the VCF’s or cutoff point and the Dynamics directly works to increase the VCF’s

cutoff point. Dynamics

QO VCF LFO Depth

Example V

This parameter sets the depth of the LFO modula-

tion that changes the cutoff point of the VCF

(=growl effect).


OG VCF Keyboard Follower

Example V

This parameter can shift the cutoff point depending

on the key played (=pitch). 0 to 15 are valid, and

decreasing the value will make the higher pitch

softer.

When the Aftertouch is controlling the cutoff fre-

quency of the VCF, this parameter sets the sen-

sitivity of the effect.


24

VCA (Voltage Controlled Amplifier)

o VCA Level

Example V

This is for changing the volume, and can be effec-

tively used when writing a tone color. When the

value is set too high, sound may be distorted.
