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.

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.
