E-38
The Synthesizer Mode of this keyboard provides the tools
for creating your own original tones. Simply select one of the
built-in tones and change its parameters to create your own
original sound. You can even store your sounds in memory
and select it using the same procedure as that used to select a
preset tone.
Synthesizer Mode Functions
The following describes how to use each of the functions
available in the Synthesizer Mode.
Synthesizer Mode Parameters
The preset tones that are built into this keyboard consist of a
number of parameters. To create a user tone, you first recall a
General MIDI tone (100 to 227) or a preset tone (000 to 099)
and then change its parameters to change it to your own tone.
Note that drum set tones (228 through 237) cannot be used
as the basis of a user tone.
The illustration below shows the parameters that make up
the preset tones and what each parameter does. As can be
seen in the illustration, these parameters can be divided into
four groups, each of which is described in detail below.

Tone Setting
Specifies which of the preset tones should be used as the orig-
inal tone.
(2) Volume Characteristic Parameters
These parameters control how the tone changes over time,
from when the keyboard key is pressed until the tone de-
cays. You can specify changes in volume and sound charac-
teristics.
■
Attack time
This is the rate or time it takes for the tone to reach its high-
est volume level. You can specify a fast rate, where the tone
reaches its highest volume level immediately, a slow rate
where it gradually rises, or something in between.
■
Release time
This is the rate or time it takes for the tone volume to fall to
zero. You can specify a release that ranges from a sudden fall
to zero, to one that gradually falls to zero.
■
Cutoff Frequency
The cutoff frequency is a parameter for adjusting timbre by
cutting any frequency that is higher than a specific frequen-
cy. A larger cutoff frequency produces a brighter (harder) tim-
bre, while a smaller frequency produces a darker (softer) tim-
bre.
