Chapter 1. Overview of the XP-30

■

Number of Simultaneous Voices

The XP-30 is able to produce up to 64 voices simultaneously.

The following paragraphs discuss what this means, and what

will happen when more than 64 simultaneous voices are

requested from the XP-30.

Calculating the Number of Voices

Being Used

The XP-30 is able to produce up to 64 simultaneous voices.

However this number is not simply the number of notes

being played, but depends on the number of Tones used in

each Patch. If you are playing one Patch which uses 4 Tones,

you will be able to play 16 simultaneous notes. If you are

using the XP-30 in Performance mode to play an ensemble,

count the total number of Tones used by all the Parts using

the following formula.

(currently sounding notes) x (number of Tones used in the

Patch being played)

How a Patch Uses Notes

When the XP-30 is requested to play more than 64 voices

simultaneously, a currently-sounding note will be turned off

to make room for the newly requested note. The note with

the lowest priority will be turned off first. The order of

priority is determined by the Voice Priority setting.

Voice Priority can be set either to Last or Loudest. When Last

is selected, a newly requested note that exceeds the 64 voice

limit will cause the first-played of the currently sounding

notes to be turned off. When Loudest is selected, the quietest

of the currently sounding notes will be turned off.

Normally you will set Voice Priority to Last.

Note Priority in Performance Mode

Since Performance mode is usually used to play an ensemble

consisting of several Patches, it is important to decide which Parts

take priority. Priority is specified by the Voice Reserve settings.

When a note within a Patch needs to be turned off to make room

for a new note, the Voice Priority setting of the Patch will apply.

Voice Reserve

The XP-30 has a Voice Reserve function that lets you reserve

a minimum number of notes that will always be available for

each Part. For example if Voice Reserve is set to 10 for Part

16, Part 16 will always have 10 notes of sound-producing

capacity available to it even if a total of more than 64 notes

(total for all Parts) are being requested. When you make

Voice Reserve settings, you need to take into account the

number of notes you want to play on each Part as well as the

number of Tones used by the selected Patch.

* It is not possible to make Voice Reserve settings that would

cause the total of all Parts to be greater than 64 voices.

Basic Operation

■ Switching Modes

The XP-30 contains a large number of functions. In order to

organize these functions for easy access, they are grouped

into the following modes. The mode that is selected will

affect the way in which the sound source operates, how data

is shown in the display, and how the function buttons work.

Use the Mode buttons to select the mode. The indicator of the

selected button will light/blink, and the display will change

according to the selected mode.

Sound Source

Selecting Patch mode, Performance mode, Rhythm Set mode,

and GM mode will determine sound source operation. One

mode always has to be selected.

Patch Mode

In this mode, you can play an individual Patch from the

keyboard or modify Patch settings. If you’re using an

external MIDI device to control the XP-30 in this mode, it will

function as a single-patch sound source.

Performance Mode

This mode makes the XP-30 function as a multitimbral sound

source, and Performance settings can be modified. If you’re

using an external MIDI device to control the XP-30 in this

mode, it will function as a multitimbral sound source.

To modify the settings of a Patch that’s assigned to a Part,

hold down [PERFORM] and press [PATCH]. Both button

indicators will light.

Rhythm Set Mode

This is how you can play a Rhythm Set from the keyboard

and modify the Rhythm Set settings. In this mode, the

keyboard will play the Rhythm Set, but the XP-30 continues

to function as a multitimbral sound source. So your effects

settings of the currently selected Performance will be heard

as you play the Rhythm Set. Rhythm Sets are assigned to Part

10 of the Performance. If you’re using an external MIDI

device to control the XP-30 in this mode, it will still function

as a multitimbral sound source.
