Creating a Patch
With the JUNO-G, you have total control over a wide variety of
settings. Each item that can be set is known as a
parameter
. When
you change the values of parameters, you are doing what is referred
to as
Editing
. This chapter explains the procedures used in creating
patches, and the functions of the patch parameters.
You can use the six SOUND MODIFY knobs to edit the sound in real time.
1.
Press MODE [PATCH] to access the PATCH PLAY screen.
2.
Select the patch whose settings you want to edit (p. 26).
You cannot edit the patches in the GM2 group.
Selecting the tone to edit
3.
In the PATCH PLAY screen, press [TONE SW/SEL] so the
button is lit.
4.
Press SELECT[1]–[4] to select the tone(s) you want to edit.
In the SOUND MODIFY 1–4 area at the bottom of the screen, a
check mark (
✔
) will be added to the tone number(s) you select.

* You can press multiple buttons simultaneously to select multiple tones.
* By turning TONE SWITCH on/off you can edit the sound while
hearing only the desired tone.
Changing the brightness of the sound and
adding special qualities (CUTOFF/RESONANCE)
The sound generator section of the JUNO-G contains a filter that can
cut or boost specific frequency regions of the sound. The CUTOFF
knob specifies the frequency (cutoff frequency) at which the filter
will begin to modify the sound, and the RESONANCE knob boosts
the region near the cutoff frequency to add a distinctive character to
the sound.
5.
Turn the CUTOFF or RESONANCE knobs.
Turning a knob toward the right increases the value.
FREQ:
Frequency at which the filter begins to have an effect on
the waveform’s frequency components
RESO:
Emphasizes the portion of the sound in the region of the
cutoff frequency, adding character to the sound
* Excessively high settings can produce oscillation, causing the sound to
distort.
Editing the way that the volume will change
The volume continues to change from the time a key is pressed to
when it is released.
6.
Press the SOUND MODIFY select button to make AMP ENV
light.
7.
Turn the ATTACK, DECAY, SUSTAIN, and RELEASE knobs.
Turning a knob toward the right increases the value.
A:
Attack Time: The time from when the keyboard is pressed
until the maximum tonal change is reached.
D:
Delay Time: The time from when the maximum tonal change
is reached until the Sustain Level is reached.
S:
Sustain level: Volume that is sustained while you hold down
the key
R:
Release Time: The time from when the keyboard is released
until the sound disappears.
* If you press the SOUND MODIFY select button so all of the
indicators are off, turning these knobs will not produce any change.
Editing the way that tone (brightness) will
change
The tone undergoes changes between the moment you press a key
until you release it.
8.
Press the SOUND MODIFY select button to make FILTER
ENV light.
9.
Turn the ATTACK, DECAY, SUSTAIN, and RELEASE knobs.
Turning a knob toward the right increases the value.
* If you press the SOUND MODIFY select button so all of the
indicators are off, turning these knobs will not produce any change.
Applying vibrato, wah, or tremolo (LFO)
The LFO, short for “low frequency oscillator,” makes changes to the
sound in periodic fashion. Vibrato is the effect produced by using
the LFO to vary the pitch. Wah is the effect produced by using the
LFO to vary the cutoff frequency. Tremolo is the effect produced by
using the LFO to vary the volume.
How to Make Patch Settings
Using the Knobs to Edit the Sound
Four Tips for Editing Patches
Select a patch that is similar to the sound you wish to
create
(p. 26)
It’s hard to create a new sound that’s exactly what you
want if you just select a patch and modify its parameters at
random. It makes sense to start with a patch whose sound
is related to what you have in mind.
Decide which tones will sound (p. 29)
Since a patch is a combination of up to any four tones, you
should listen to how the individual tones sound before you
edit. Then decide which tones you are going to use. It is
important to turn off unused tones to avoid wasting voices,
unnecessarily reducing the number of simultaneous notes
you can play.
Check the Structure setting (p. 35)
The important Structure parameter determines how the
four tones combine. Before you select new tones, make
sure you understand how the currently selected tones are
affecting each other.
Turn Effects off (p. 125)
Since you will hear the original sound of the patch itself
when the effects are turned off, the results of your
modifications will be easier to hear. Actually, sometimes just
changing effects settings can give you the sound you want.
