The VL sounds better
It has more depth, and is more realistic in the musical sense than any other synthesizer system.

Simply pressing a key
In the same way does not always produce precisely the same sound. The instrument is responsive and "alive".

Note-to-note transitions
Have the same continuity exhibited by acoustic instruments. What goes on in between the notes is just as important musically as the notes themselves.

It has extraordinary expressive capability
Rather than simply controlling parameters like volume or pitch, you can control characteristics such as breath and reed pressure with approximate complex effects on the timbre of the sound.

The VL1 Model
The overall VL1 model or "algorithm" consists two "elements", each including three main blocks: the instrument, controllers, and modifiers. The two elements actually function as independent tone generators, so although it is basically a monophonic solo instrument the VL1 can produce two notes at once. The two elements can also be used as layers of a single voice.

The Instrument
The key block in this algorithm is the instrument, since it is here that the fundamental tone or "timbre" of the sound is defined. Internally the instrument model consists primarily of a driver - the reed/mouthpiece, lip/mouthpice, or bow/string system - and a resonant system corresponding to the tube and air column or string. One main difference between the VL1 and an acoustic instrument is just about any driver can be used with any type of pipe or string, resulting in totally new instruments with "acoustic" properties and expressive power.

The Controllers
The controller parameters determine how the instrument "plays". All of these parameters can be assigned to any of the external controllers that can be used with the VL1: the breath controller, foot controller, modulation wheels, etc.: pressure, embouchure, pitch, vibrato, tonguing, amplitude, scream, breath noise, growl, throat format, dynamic filter, harmonic enhancer, damping, absorption.

The Modifiers
Although you don't have direct programming access to the VL1 instrument block, the modifiers allow a significant degree of control over the final timbre of the voice. The modifiers block consists of 5 sections: harmonic enhancer, dynamic filter, frequency equalizer, impulse expander, resonator.

Virtual Acoustic Synthesizer
It produces sound in an entirely new way. No oscillators or function generators, no preset waveforms or samples. The VL1 represents the world's first practical application of computer-based "physical modeling" in musical sound synthesis, generating sound using the same principles as acoustic instruments.
