Voice Structure & Editing Hints
Although the EX Extended Synthesis tone generator system is quite complicated, the overall system
and interface have been designed to make voice editing as easy and efficient as possible. A thorough
understanding of the system will depend on familiarity with the individual parameters connected with
each tone generator type (see list, below), but in this section we'll provide some information that may
help in grasping how everything fits together, and perhaps in developing an organized approach to
voice editing on the EX5/5R/7.
For details on the individual parameters connected with each tone generator type, see the following

System Overview

Individual Element Structure
Any EX voice, no matter what tone generator type it uses, can have anywhere from one to four
"elements." The structure of each element consists of four "stages" as shown in the block diagram
below.
OSCILLATOR
Although the individual parameters available in each stage will vary to some degree depending on
the type of tone generator being edited, the basic function of each stage is the same.
OSCILLATOR
This stage is not really an "oscillator" in the traditional sense of the word, but it is here that the
basic sound of the voice is produced.
In an AWM element, the "oscillator" is the waveform or sample on which the voice is based.
In a VL element (EX5/5R only), it is the instrument model: the reed/mouthpiece,
lip/mouthpiece, or bow/string system plus the resonant system corresponding to the tube and
air column or string.
In an AN element it is the simulated VCO (Voltage Controlled Oscillator) of the simulated
analog synthesis system.
Since FDSP elements are based on AWM synthesis, an AWM oscillator stage is the same as in
an AWM element.
