Patches<br />

Patches are the basic sound configurations that you play<br />

during a performance. Each Patch can be configured by<br />

combining up to four Tones. How the four Tones are<br />

combined is determined on the STRUCT display (PATCH/<br />

COMMON).<br />

Rhythm Sets<br />

A Rhythm Set is a grouping of percussion instruments<br />

(Rhythm Tones). Since percussion instruments generally do<br />

not play melodies, there is no need for a percussion<br />

instrument sound to be able to play a scale on the keyboard.<br />

It is however, more important that as many as possible<br />

percussion instruments be available to you at the same time.<br />

Therefore, each key (Note number) of a Rhythm Set will<br />

produce a different percussion instrument.<br />

Performances<br />

The next level in sound configuration. A single Performance<br />

groups 15 Patches and one Rhythm Set so that they can be<br />

combined to play ensembles or produce fabulously rich,<br />

thick sounds. One Performance allows a single XP-30 to<br />

control up to 16 instrument sounds. Because the XP-30 sound<br />

source can control multiple sounds (instruments) it is called a<br />

“multitimbral sound source.”<br />

Parts<br />

When the XP-30 is used as a multitimbral sound source,<br />

another sound configuration called a Part comes into play. A<br />

Part contains a Patch or Rhythm Set. For multitimbral<br />

applications, the Performance consists of 16 Parts. A specific<br />

Patch can be assigned to each Part except Part 10 because<br />

Part 10 is universally set as the Drum Part to which a Rhythm<br />

Set (discussed above) is assigned. In a multitimbral context, it<br />

helps to think of a Performance as an orchestra, each Part in<br />

it being a musician, and the Patch or Rhythm Set that<br />

musician’s instrument.<br />
