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.
fig.04-031.e
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)
Range: 1–1083
Selects the desired waveform by its number.
The name of the wave will be displayed in square brackets [
].
* When Wave Number R is set to "----," the tone being edited
goes to MONO.
* By holding down [SHIFT] and pressing [F6], you can rapidly
switch between STEREO and MONO tones.
