libraries are of this type.
Multi-Partial Patches are created by assigning the constituent
sounds, called Partials, to the keys on the keyboard, with up
to 88 Partials being assignable.
One difference between Tones and Partials is that whereas
Tones are composed of two waveforms, Partials may contain
up to four samples (Wave data).
* Multi-Partial Patches are created using samples (Wave data)
loaded into the SIMM (memory module) (internal Waves
cannot be used). To do this, you need a separate device to load
the samples from a sampler library or other source to the XV-
5080. (p. 181)

How a Partial Is Organized

are called Partials. Partials may comprise up to four samples,
and are composed using the following five elements.
SMT (Sample Mix Table)
Selects the sample to be used as the source of the sound.
You can use the key touch and MIDI messages to control the
way each sample is played.

TVF (Time Variant Filter)
Specifies how the constituent frequencies of the Tone will
change.
TVA (Time Variant Amplifier)
Specifies how the volume will change, and controls the
localization.
Envelope
An envelope applies changes to the Tone over time. There
are separate envelopes for Pitch, TVF (filter), and TVA
(volume). For example, you would use the TVA Envelope to
modify the way in which the Tone attacks and decays.
The TVF envelope can be used to change not only the cutoff
frequency, but also the pitch.
LFO (Low Frequency Oscillator)
Use the LFO to create cyclical changes—or cyclical
"modulation"—in a Tone. Each Tone has an LFO. An LFO
can be applied to the Tone's pitch settings, TVF (filter), and
TVA (volume). When an LFO is applied to pitch, a vibrato
effect is produced. When an LFO is applied to the TVF cutoff
frequency, a wah-wah effect is produced. When an LFO is
applied to the TVA volume, a tremolo effect is produced.
Selecting the Tones That Will
Sound (Tone On/Off)
Here's how to turn on the Tones that you want to hear in a
Patch. You can also use the on/off technique described in
this section to audition an individual Tone by turning off all
the other Tones in a Patch.
Select the Patch you wish to use.
1. Make sure that the PATCH PLAY page is displayed.
2. Hold down [SHIFT] and press TONE SW [1]–[4] to
switch the corresponding Tone on so that its indicator
lights, or off so that its indicator goes dark.
3. The PATCH PLAY page indicates the Tones that are on
as follows. Tones that are off are shown as "-."
