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.

Using the Tone Synthesizer
You cannot use tones 228
237 (drum set
tones) as base tones.
The preset tone you use as the basis for a
user tone is not changed.
Tone locations 238
247 initially contain the
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
.
While you are setting the three DSP
parameters, an indicator appears next to
DSP.

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
achieve!
