instrument’s character. The XV-3080 provides a variety of waveforms containing realistic acoustic instrument attacks. To obtain the maximum realism when using these waveforms, it is best to leave the filter wide-open during the attack so that all of these important timbral changes are heard. If you use an envelope to modify the attack portion, you may not achieve the result you want. Use enveloping to produce the desired changes in the decay portion of the sound.

If you try to make a waveform’s attack brighter by lowering the high-frequency content of its decay using the TVF filter, consider the original timbral character of the waveform. If you’re making a part of the sound brighter than the original waveform, you should first generate new upper harmonics not present in the original waveform using the Color and Depth parameters (FXM page) before filtering. This will help you achieve the desired result. To make an entire waveform brighter, try applying effects such as an enhancer and equalizer before modifying the TVF parameter.

Modifying a Waveform (WAVE)

This set of parameters allows you to select the PCM waveform that serves as the basis for the currently selected Tone, apply effects to the waveform, and control its pitch.

WAVE

Group (Wave group type)

This selects the desired waveform’s group.

INT:Internal

XP-A–F:Wave Expansion Boards A–F

*It is not possible to select XP-A–Funless a wave expansion board is inserted into the corresponding slot.

Number (Wave Number)

This selects the desired waveform by its number. You can choose a separate waveform for each of the XV-3080’s left

and right channels.

The selected wave’s name will appear to the right of the wave number parameter.

Gain (Wave gain)16/0/+6/+12

This specifies the gain (or 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.

Switch (TMT tone switch)ON/OFF

This 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.

*When TONE SW [1]–[4] are turned on or off, this setting will also change.

*You can also turn Tones on and off on the PATCH PLAY page. (p. 84)

Wave Tempo SyncON/OFF

This determines whether the waveform is synchronized (ON) or not synchronized (OFF) to the Patch’s tempo.

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 (Wave FXM switch)ON/OFF

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

Color (Wave FXM color)1–4

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

Depth (Wave FXM depth)0–16

This specifies the depth of the modulation produced by FXM.

TONE DELAY

This produces a time delay between the moment a key is pressed (or released) and the moment the Tone actually begins to sound. Since you can adjust the timing of each Tone in a Patch, you can create effects in which pressing a single key produces two or more sounds occurring at different times.

If you do not wish to use Tone Delay, set Mode to NORMAL and Delay Time to 0.
