Internal Structure (System Overview)
Voice, Performance, and Mixing
This instrument features three different types of programs,
that form the basis for creating and playing sounds.
Voice
A program that contains the sonic elements for generating a
specific musical instrument sound is referred to as a "Voice."
Each Voice consists of up to four elements (Normal Voice) or
up to 73 keys (Drum Voice). Each Voice is created by editing
parameters unique to each element/key and parameters
common to all the elements/keys in the Voice mode (page
188) or in the Mixing Voice mode (page 249).
Performance
A program in which multiple Voices (parts) are combined in a
layer, or in other configurations is referred to as a
One Voice

"Performance." Each Performance can contain up to four

common to all the parts in the Performance mode (page 212).
Mixing
A program in which multiple Voices are assigned to Parts for
multi-timbral play in the Song and Pattern modes is referred to
as a "Mixing." Each Mixing can contain up to 34 parts (page
163). Each Mixing can be created by editing parameters
unique to each part and parameters common to all the parts
in the Song Mixing mode (page 233) or in the Pattern Mixing
mode (page 248).
