About Patches and Performances
On the XV-2020, sounds are organized according to units called Tones, Patches,
Rhythm Sets, and Performances. This section describes the relationship between
a Patch and a Performance.
What is a Patch?
The type of sound most commonly played on the XV-2020 is called a Patch. A Patch
is a combination of Tones, which are the smallest units of sound. Each Patch can
contain up to four Tones. If we use the analogy of an orchestra, then Patches are the
musical instruments of the performers.
* For information on Tones, see p. 44.

* You can turn the Tones in a Patch on or off. Only Tones that are turned on are heard when
you play the Patch (p. 45).
What is a Performance?
It may be easiest to think of a Performance as being the orchestra itself.
To continue the orchestra analogy, a Performance is made up of the parts assigned
to the respective instruments (called, naturally enough, “Parts”). You can enjoy
ensemble play by combining a total of 16 Patches or Rhythm Sets into one such Part.

In other words, a Performance allows you to produce sixteen separate sounds with
a single XV-2020.
