Rhythm Sets - Roland XP-30 Owner's Manual

Patches
Patches are the basic sound configurations that you play
during a performance. Each Patch can be configured by
combining up to four Tones. How the four Tones are
combined is determined on the STRUCT display (PATCH/
COMMON).

Performances
The next level in sound configuration. A single Performance
groups 15 Patches and one Rhythm Set so that they can be
combined to play ensembles or produce fabulously rich,
thick sounds. One Performance allows a single XP-30 to
control up to 16 instrument sounds. Because the XP-30 sound
source can control multiple sounds (instruments) it is called a
"multitimbral sound source."

Rhythm Sets

A Rhythm Set is a grouping of percussion instruments
(Rhythm Tones). Since percussion instruments generally do
not play melodies, there is no need for a percussion
instrument sound to be able to play a scale on the keyboard.
It is however, more important that as many as possible
percussion instruments be available to you at the same time.
Therefore, each key (Note number) of a Rhythm Set will
produce a different percussion instrument.

Parts
When the XP-30 is used as a multitimbral sound source,
another sound configuration called a Part comes into play. A
Part contains a Patch or Rhythm Set. For multitimbral
applications, the Performance consists of 16 Parts. A specific
Patch can be assigned to each Part except Part 10 because
Part 10 is universally set as the Drum Part to which a Rhythm
Set (discussed above) is assigned. In a multitimbral context, it
helps to think of a Performance as an orchestra, each Part in
it being a musician, and the Patch or Rhythm Set that
musician's instrument.
