What Is A Voice; An1X Memory Structure; System Data - Yamaha AN1x Owner's Manual

What Is A Voice?

Over the years, the meaning of the term "voice", when
applied to synthesizers, has varied depending on
manufacturers and models. In general, it means a sound,
which in some synths is called a "patch", and in others a
"program".
With the AN1x, a voice is a configuration of all tone
generator and other parameter settings, including effects
setups and data for a single Voice Pattern, but excluding
system settings or the bank of Step Sequencer User
Patterns. Therefore, each of the 128 voices in memory
can have its own unique configuration of all main
parameters.

AN1x Memory Structure

The AN1x has a simple and straightforward memory structure. There
are only two main types of data: voice data and system data. There
is also a separate memory for the Step Sequencer User Pattern bank.
Voice Data
Voice data is comprised of the various parameter
settings which make up each of the 128 User voices,
as follows:
Tone generator settings based on CONTROL knob
positions for each KNOB PARAMETER GROUP
parameter, PORTAMENTO switch status, Scene
status and Scene-related parameters, including
Control Matrix assignments, Mode settings and
Variation Effect Dry:Wet setting.

System Data

System data is made up of the various "global"
parameter settings which remain in effect regardless of
which voice is selected, as follows:
UTILITY SETUP parameters, including the settings for
System tuning and keyboard transposition and
velocity, MIDI-related parameters, and Control
device and number assignments.
User Pattern Data
User Pattern data is made up of the Step Sequencer
User Pattern bank which holds 128 User Patterns.
