Basic program editing

Select the program that you wish to edit in Program Play mode ( page 13 in this manual), and
enter Program Edit mode to edit it.
After making these edits, you can go ahead on your own, and call up various preset programs and
edit them as you review the basic structure of a program ( page 28 in this manual). Even if you
end up with a sound that you don't like, you can always load the factory preset data back into
memory ( page 25 in this manual) to restore the original sounds.
The best way to gain an understanding of what the parameters do is to go ahead and edit them. As
you continue editing sounds, you will soon come to understand how a synthesizer works, and the
function of each parameter.
Amplifier settings
When a note is played on an instrument such as a piano or an organ, the sound immediately
reaches its maximum volume. However on string instruments such as a violin, the volume usually
increases more gradually.
The time from when a note is played until it reaches its maximum volume is called the Attack
Time.
A note played on a piano gradually decays even if you continue holding down the key. A note on
an organ continues at the same volume as long as you hold down the key. In this way, the time
over which the sound diminishes differs between instruments. This decrease of the volume level
is called "decay."
When you release your hands from the piano keyboard (Note Off), you will hear some reverbera-
tion. This is called "release."
In this example, let's adjust the attack time of a piano sound.
The attack time of a sound is adjusted in Program Edit mode P5, in the second tab screen (Amp
EG), by the parameters Level and Time.
Press the [PROG] key to enter Program Play mode.
1
Use the [BANK] key and the VALUE controllers to select bank A, 001: Acoustic Piano.
2
If bank A does not contain 001: Acoustic Piano, use the procedure described in "Restoring the fac-
tory preset data" ( page 25 in this manual) to load the PRELOAD1.PCG file or P_LOAD1.PCG
before continuing.
Press the [EDIT] key.
3
You will enter Program Edit mode.
Press the [P5] key.

Page 5 will appear.
Press the second tab button in the display (Amp 1
5
EG).
The Amp 1 EG display will appear.
Select LEVEL, and specify the value, using the
6
VALUE controller. Here, set the following value for
each parameter:
Start Level: 00, Attack Level: 99, Break Point
Level: 50, Sustain Level: 80
Select the Time parameters using the VALUE controllers to set the value for each parameter.
7
Set the following values here:
Attack Time: 20, Decay Time: 30, Slope Time: 50, Release Time: 30
Use the VALUE controllers to modify the values.
8
While repeatedly playing a note on the keyboard, adjust the Attack Time value and notice how the
sound changes. With higher settings the sound starts more gradually. With a setting of about 50,
the piano sound has become more like a cello. In this way, the character of a sound can be dramat-
ically changed simply by adjusting the attack.
While repeatedly playing notes on the keyboard, adjust the Decay Time value and notice how the
sound decays.
While repeatedly playing notes on the keyboard, adjust the Release Time value and notice how
the sound changes.
