Modifying Waveforms (WAVE)

Select the PCM waveform that is to be the basis of the Tone, and apply effects to the waveform.

WAVE

Group (Wave Group)

Selects the group for the waveform that is to be the basis of the Tone.

INT: Waveforms stored in internal memory

XP-A–D: Waveform stored in a Wave Expansion Board installed in EXP A–D slots.

You cannot select a waveform group of a Wave Expansion Board that is not installed.

Number (Wave Number)

Selects the basic waveform for a Tone. Along with the Wave number, the Wave name appears at the right of the display. When in monaural mode, only the left side (L) is specified.

When in stereo, the right side (R) is also specified.

The Wave numbers can be divided and set in the first two and last two digits.

Gain (Wave Gain)

Specifies the gain (amplitude) of the waveform. The value changes in 6 dB (decibel) steps—an increase of 6 dB doubles the waveform’s gain. If you intend to use the Booster to distort the waveform’s sound, set this parameter to its maximum value (p. 75).

Switch (Tone Switch)

Determines whether or not the Tone will be heard in the Patch. In order to make best use of the available number of simultaneous voices, unused Tones should be turned off.

You can also set the Switch parameter on the PATCH PLAY page. Press TONE SWITCH [1]–[4] to switch the setting to ON (indicator lighted), or OFF (indicator extinguished) (p. 32).

Chapter 5. Creating Patches

Wave Tempo Sync

When you wish to synchronize a Phrase Loop to the clock (tempo), set this to ON. This is valid only when an optional Wave Expansion Board, such as “SR-JV80-10: BASS&DRUMS,” is installed, and you have selected a Tone which uses a waveform that displays tempo (BPM). For details, refer to “Playing Phrase Loops in Sync with the

System Tempo” (p. 201).

When the Wave Tempo Sync parameter is set to ON, settings related to Pitch (p. 86) and FXM (p. 81) are disabled.

When the Wave Tempo Sync parameter is set to ON, set the Time parameter (PATCH/WAVE/TONE DELAY) to 0. With other settings, a delay effect will be applied, and you will be not be able to play as you expect.

What is a Phrase Loop?

A Phrase Loop is a portion of a song that is excerpted with a sampler or by other means, and then played back repeatedly. One technique involving the use of Phrase Loops is the excerpting of a Phrase from a pre-existing song in a certain genre, for example dance music, and then creating a new song with that Phrase used as the basic motif. This is referred to as “Break Beats.”

FXM (Frequency Cross Modulation)

FXM (Frequency Cross Modulation) uses a specified waveform to apply frequency modulation to the currently selected waveform, creating complex overtones. This can be useful when creating wilder sounds or sound effects.

Switch (FXM Switch)

This sets whether FXM will be used (ON) or not (OFF).

Color (FXM Color)

Specifies how FXM will perform frequency modulation. Higher settings result in a grainier sound, while lower settings result in a more metallic sound.

Depth (FXM Depth)

Specifies the depth of the modulation produced by FXM.
