Modifying the Waveform and Pitch F2 WG, 136

Chapter 4 Creating Patches

The following diagram shows an example of a sound – an

electric organ – that combines one-shot and looped

waveforms.

Notes for Editing One-Shot Waveforms

You cannot give a one-shot waveform a longer decay — or make it into a sustaining sound — by using an envelope. If you were to program such an envelope, you would be attempting to shape a portion of the sound that simply doesn’t exist, and the envelope would have no effect.

Notes for Editing Looped Waveforms

With many acoustic instruments such as piano and sax, extreme timbral changes occur during the first few moments of each note. This initial attack is what defines much of the instrument’s character. The XV-5080 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 parameter in the Patch WG Prm

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 the Waveform and Pitch ([F2] (WG))

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)

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

Available Settings:

INT: Waveform stored in the XV-5080’s memory.

XP-A–H:Waveform on the wave expansion boards A–H.

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

SAMPLE: Samples (Wave data) loaded into the SIMM (memory module) from a sampler library or other source.

L (Wave Number L)

Range: 1–1083

Selects the desired waveform by its number.

The name of the wave will be displayed in square brackets [ ].

R (Wave Number R)
