What Is A Voice - Yamaha SY77 Operating Manual

Each Normal voice consists of settings for one two or four AFM or AWM elements (Element data) and
settings which affect the entire voice (Common data). Each Drum voice consists of a different AWM
sampled sound for each of the SY77's 61 keys.

What is a Voice

The SY77 contains a 16 note AFM tone generator and a 16 note AWM tone
generator. The Voice Mode setting determines how these tone generators are
used to create a Voice, and how many elements are used for each note you play.
Each voice uses one of these eleven voice modes.

11 Drum Set
Voices created using modes 1-10 consist of Common data that affects all ele-
ments, and Element data for one two or four elements.
Common data includes a complete set of Effect data for the four DSP units,
Controller data such as pitch bend and aftertouch assignments, and Other data
such as microtuning table selection, random pitch fluctuation, and portamento
settings. Common data also contains settings such as element volume level,
detune, note shift, note limit, and velocity limit for each element.
Element data includes AFM or AWM data for one two or four AFM or
AWM elements. The voice mode will determine whether each element uses
AFM tone generation or AWM tone generation. Details of AFM and AWM
element data are covered separately in following sections.
