Synthesizer Mode
The Synthesizer of this keyboard provides all the tools you need 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 for later recall using the
same procedure as that used to select a preset tone.
Synthesizer Functions
The following describes how to use each of the functions available
with the Synthesizer.
Synthesizer Parameters
The sounds of the preset tones built into this keyboard are controlled
by settings called “parameters.” To create a user tone, you first recall
a preset tone and then change its parameters. Note that drum set
tones (192 through 199) cannot be used as the basis of a user tone.
The figure below shows the parameters that make up the preset tones
and what each parameter does. As you can see, these parameters can
be divided into four groups, each of which is described in detail in
the following pages.
This parameter affects
tone characteristics.
● PCM set
This parameter affects
volume.
● Amp envelope set
These parameters affect
pitch.
● Pitch
● Pitch envelope set
These parameters affect
volume, tone quality, and
how notes are sounded.
● Attack rate
● Release rate
● Level
● Touch sensitivity
● Filter sensitivity
● Filter level
● Pan
● Transpose
Output
(1) Tone Characteristic Parameter
■ PCM Set
This parameter determines the characteristics of a tone by switching
its digitally sampled waveform. You can select a piano, guitar, syn-
thesizer, or any other of a variety of musical instrument and digitally
sampled waveforms.
(2) Volume Characteristic Parameter
■ Amp Envelope Set
This set gives you a choice of a variety of different volume envelopes
(changes in volume over time): slow attack when a key is pressed,
quick attack when a key is pressed, continued sound while a key is
depressed, etc.
(3) Tone Pitch Parameters
■ Pitch
This parameter controls the overall pitch of the tone.
■ Pitch Envelope Set
This parameter provides a variety of pitch envelopes from which you
can choose.
❚ NOTE ❚
Pitch envelope 00 selects “No change (flat),” 01 through 17 selects “Vibra-
to,” and 18 through 45 selects “Other.”
(4) Volume, Tone Quality, Parameters
■ Attack Rate
This parameter lets you set the speed of the attack (the period from
the point when you press a key to the point that the tone reaches its
maximum volume). Use this parameter to make fine adjustments to
the tone characteristics of the amp envelope you are using.
