What Is A Voice - Yamaha SY99 Owner's Manual

Each normal voice consists of settings lor 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 wave-
form for each of the SY99's 76 keys.
The Voice Mode deter-
mines the number of

What is a voice?

The SY99 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.

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.
