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 (any of the preset tones 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 on the display. The display also shows whether the tone you selected is a DCO1 O2 tone (if it is a layered tone).

Note: To cancel the save operation at any time, press TONE, or press SYNTH 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.

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 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 adjust- ments to the tone characteristics of the amp envelope.

Pitch Envelope Set (PitchSet) (0 to 49) — Selects the pitch enve- lopes. 00 specifies no change, a value from 01 to 19 changes the vibrato, and a value from 20 to 49 changes a parameter other than the vibrato.

Pitch (Pitch) (–64 to +63) — Controls the overall pitch of the tone. A positive value increases the pitch, a negative value lowers it. A setting of zero sets the pitch to the standard setting for the selected tone.

Level (Level) (0 to 127) — Con- trols the 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.
