The keyboard's custom tone synthesizer
lets you create up to 32 of your own original
tones. To create a "user" tone, you simply
select one of the keyboard's 100 preset
tones or 127 GM tones, change its para-
meters, then store the new tone in a
memory location from 238 to 247. You
select and use a user tone as you would a
preset tone. ±
The parameters you can change are divided
into the following groups. ±
• Volume Characteristic — Attack Time,
Release Time, Resonance, Cutoff
Frequency
• Tone Pitch — Vibrato type, Vibrato
Delay, Vibrato Depth, Vibrato Rate,
Octave Shift
• Tone Characteristic — Level, Touch
Sense, Reverb Send, Chorus Send,
DSP Line, DSP Type, DSP Parameter
1. Select the preset tone (except 228–
237) you want to use as a basis for your
user tone.
2. Press . The keyboard enters the

parameter) appears.
3. Repeatedly press I or J (
display the parameter you want to
change.
Attack Time ( ) (
Sets the speed of the attack (the period
from when you press a key to when the
tone reaches its maximum volume). The
greater the value, the quicker the attack.
Release Time (
Controls the speed of a tone's release
(the period from when you release a
key to when the tone stops sounding).
The greater the value, the quicker the
release.
Vibrato Type (
— Sets the vibrato type as sine
wave ( ), triangle wave ( ), sawtooth
wave ( ), or square wave (

brighter timber, lower cut off frequency
produces a softer timbre.
Resonance (
Sets the resonance of the tone.
Resonance enhances the harmonic
component around the cut off frequency
to create a distinctive sound. The larger
the value, the more distinctive the
sound. ±
Octave Shift (
Shifts the range of the tone up or down
by octave.
Level (
overall volume of the tone. The greater
the value, the greater the volume.
Setting a level of zero means that the
tone does not sound at all.

Using the Tone Synthesizer

• You cannot use tones 228

• The preset tone you use as the basis for a
)
EXIT
user tone is not changed.
• Tone locations 238
tone number 000. The user tone you store
in any of those locations replaces it.
Creating and Storing a User Tone
• A new or revised user tone replaces the
existing user tone.
• Layer, split, auto accompaniment, demo
tune play, and MIDI functions are all
disabled while the keyboard is in the
) —
Custom Tone Synthesizer mode.
• For some tones, setting the resonance too
high might cause distortion or noise. If you
encounter this, lower the resonance setting.

• To make it easier to create your own tone,
start with a preset tone that is similar to the
one you are trying to create.
• Experiment with different settings. There are
no real rules about what a tone should
sound like. Let your imagination run free
and experiment with different combinations.
You might be surprised at what you can
