note is held, allowing wave memory to be used more
efficiently. The XV-3080’s looped waveforms also include
components of other sounds, such as piano-string resonant
vibrations and the hollow sounds of brass instruments.
The following diagram shows an example of a sound – an
electric organ – that combines one-shot and looped
waveforms.
fig.6-04.e
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-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.
fig.6-05.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) 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 (RHYTHM/
TVF).
Modifying a Rhythm Tone’s
Waveform and Panning (WAVE)
TONE NAME
You can name a Rhythm Tone using up to 12 alphanumeric
characters.
Use [ ]/[ ] to move the cursor, and then turn the
[VALUE] knob or press [INC]/[DEC] to select the desired
character.
Available characters/symbols:
space, A–Z, a–z, 0–9, ! “ # $ % & ‘ ( ) * + , - . / : ; < = > ? @ [ \ ]
^ _ ?

Press [SHIFT] to display the following in the bottom right
corner of the screen.
fig.6-06
A a: Switches between uppercase and lowercase
characters.
INS: Inserts a space at the cursor location and shifts the
remaining text to the right by one character position.
DEL: Deletes the character at the cursor and shifts the
remaining text one character position to the left.
Press each of these buttons in order to execute its
corresponding function (refer to the figure).

WMT WAVE
With the XV-3080, up to four stereo Waves can be assigned to
a single Rhythm Tone. You can select the way tones sound
according to the force with which the keys are played, thus
allowing you to create Rhythm Tones featuring great
expressive power. This function is called
