Tone Generator Block<br />

The tone generator block is what actually produces sound in response to the MIDI messages received from the<br />

Sequencer block, the Controller block, the Arpeggio block and from the external MIDI instrument via the MIDI IN<br />

connector or the USB connector. The MIDI messages are assigned to sixteen independent channels, and this<br />

synthesizer is capable of simultaneously playing sixteen separate parts, via the sixteen MIDI channels. However, the<br />

sixteen-channel limit can be over<strong>com</strong>e by using separate MIDI “ports,” each supporting sixteen channels. The tone<br />

generator block of this instrument can handle MIDI messages over Port 1. The structure of the tone generator block<br />

differs depending on the mode.<br />

Tone Generator Block in the Voice Mode<br />

Part structure in the Voice mode<br />

Only one MIDI channel can be recognized in the Voice mode because only one part is available in this<br />

mode. This status is referred to as a “single timbre” tone generator. A Voice is played from the keyboard,<br />

using a single part.<br />

To set the MIDI receive channel for single timbre operation (Voice and Performance modes), use the<br />

Basic Receive Ch parameter (page 137) in the Utility MIDI display. In the Voice mode, the instrument<br />

recognizes only data over MIDI Port 1.<br />

NOTE If you want to play song data on an external MIDI sequencer or <strong>com</strong>puter consisting of multiple MIDI<br />

channels, make sure to use the Multi mode (page 6).<br />

Voice<br />

A program that contains the sonic elements for generating a specific musical instrument sound is<br />

referred to as a “Voice.” Internally, there are two Voice types: Normal Voices and Drum Voices. Normal<br />

Voices are mainly pitched musical instrument type sounds that can be played over the range of the<br />

keyboard.<br />

Each Voice consists of up to eight Elements (Normal Voice) or up to 73 keys (Drum Voice).<br />

An Element or Drum Key is the basic and the smallest unit for a Voice. This means that only one Element<br />

or key can produce the musical instrument sound. In addition, a Normal Voice can produce the realistic<br />

sound or various types of sound by <strong>com</strong>bining multiple Elements. Each Voice is created by editing<br />

parameters unique to each element/key (Element Edit parameters/Key Edit parameters) and<br />

parameters <strong>com</strong>mon to all the elements/keys (Common Edit parameters). In Element Edit and Key Edit,<br />

you can edit the parameters only on the <strong>S90</strong> <strong>XS</strong>/<strong>S70</strong> <strong>XS</strong> Editor.<br />

NOTE For instructions on editing a Normal Voice, see page 34. For instructions on editing a Drum Voice, see page<br />

58.<br />

Normal Voices & Drum Voices<br />

Normal Voices<br />

This is a Voice which is played conventionally from<br />

the keyboard, with standard pitches sounding for<br />

each key. A Normal Voice consists of up to eight<br />

Velocity<br />

Element 2 Element 4 Element 6<br />

Elements. Depending on the settings in the Voice<br />

Edit mode, these Elements are sounded<br />

simultaneously, or the different Elements are<br />

sounded according to the note range, velocity<br />

range and the XA (Expanded Articulation) settings.<br />

Element 1 Element 3 Element 5<br />

The illustration is an example of a Normal Voice. Since the six Elements here are distributed across both<br />

the note range of the keyboard and the velocity range, a different Element sounds depending on which<br />

note you play and how strongly you play it. In the note distribution, Elements 1 and 2 sound in the lower<br />

range of the keyboard, Elements 3 and 4 sound in the middle range, and Elements 5 and 6 sound in the<br />

higher range. In the velocity distribution, Elements 1, 3 and 5 sound when playing the keyboard softly,<br />

while Elements 2, 4 and 6 sound when playing it strongly. In a practical example of this in use, a piano<br />

Voice could be <strong>com</strong>posed of six different samples. Elements 1, 3 and 5 would be the sounds of the<br />

piano played softly, over the respective note ranges, while Elements 2, 4 and 6 would be strongly<br />

played sounds, for each respective note range. Actually, the <strong>S90</strong> <strong>XS</strong>/<strong>S70</strong> <strong>XS</strong> is even more flexible than<br />

this, since it allows up to eight independent Elements.<br />
