Understanding 1DCO and
2DCO Tones
A Digital Controlled Oscillator (DCO)
controls the sound output of a digital sig-
nal. Some of the keyboard’s built-in
tones are simple tones (1DCO), and
some are layered tones (2DCO). When
you select a 2DCO tone as the basis for
creating a user tone, you need to
change the parameters of both tones.
When you select a layered tone,
dCo1
appears, indicating that this is the first
tone of a layered tone.
Creating and Storing a User
Tone
Follow these steps to create and store
your own tone. (Refer to “Hints on Cre-
ating a User Tone” on Page 23.)
Notes:
• 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.
1. Select the preset tone (except 160–
167) you want to use as a basis for
your user tone.
2. Press
SYNTH
. The keyboard enters
the Custom Tone Synthesizer mode
and the first parameter (PCM Set)
appears. The display also shows
whether the tone you selected is a
DCO1
or
DCO2
tone (if it is a layered
tone), and shows the current PCM
setting.
For example, if you selected tone 19
(Church Organ),
019 ChrchOrg
appears. Then, when you press
SYNTH
,
026 ChrchOrgA
appears.
Note:
To cancel the save operation
at any time, press
SYNTH
or
TONE
twice.
3. Repeatedly press or to display
the parameter you want to change.
PCM Set (0 to 173)
— Determines
the characteristic of a tone by
changing its digitally sampled wave-
form.
Amp Envelope Set (
Amp.Set
) (0
to 137)
— Selects the volume enve-
lopes. 000 to 048 set volume enve-
lopes for a decaying note (how fast
or slow the sound diminishes). 049
to 137 set volume envelopes that
sustain the note. Samples of the
amp envelopes appear in a graph
near your keyboard’s right speaker.
Attack Rate (
Atk Rate
) (1 to 127)
— 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. Use this parame-
ter to make fine adjustments to the
tone characteristics of the amp
envelope.
Release Rate (
Rel.Rate
) (1 to
127)
— 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.
Use this parameter to make fine
adjustments to the tone characteris-
tics of the amp envelope.
Pitch Envelope Set (
PitchSet
)
(0 to 49)
— Selects the pitch enve-
