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 percussion instruments as possible be available to you at the same time. Therefore, each key (note number) of a Rhythm Set will produce a different percussion instrument.

Performances

Chapter 1

 

A Performance is a collective set of assignments of the sixteen different Patches and Rhythm Sets. Since a Performance can simultaneously handle 16 different sounds, it allows you to play multiple Patches simultaneously (layer) or to play different Patches in different areas of the keyboard (split), and to create ensembles.

Because the XV-88 sound generator can control multiple sounds (instruments) it is called a Multi-timbral sound

generator.

Parts

Parts are the “sites” to which the Patches and Rhythm Sets used by the XV-88 as sound material are assigned. A single Performance comprises sixteen Parts, with a Patch or Rhythm Set being assigned to each Part.

In the relationship between Performances and Parts, the Performance is like an orchestra, the Parts the performers, and the Patches and Rhythm Sets the instruments.
