Analog Physical Modeling Synthesis and the AN200
At the heart of the AN200’s stunning, dynamic analog-like sound is a highly sophisticated
and versatile tone generating method — the Analog Physical Modeling Synthesis system.
and versatile tone generating method — the Analog Physical Modeling Synthesis system.
We won’t try to explain how Analog Physical Modeling works — that would take several
pages. Besides, you can hear for yourself the enormous power and punch this system
delivers. In this section, we’ll just briefly outline the structure of the AN200, and show you
what happens to the sound within the AN200 system as it’s generated, processed and
enhanced.

Very simply, there are three basic elements of sound: pitch, tone (or timbre) and volume (or “amplitude” in
synth-speak). Within the AN200, these three elements are created or controlled by the VCO (oscillator), VCF
(filter), and VCA (amplifier).

And that’s basically how the AN200 creates sound. Of course, there are a few other elements in the system
