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.
 
 
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
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
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
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
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.
