VL70-m Controller Parameters

Any of the physical controllers listed above can be assigned to control any of the VL70-m’s controller parameters:

Pressure

The amount of breath pressure applied to a reed or mouthpiece,

 

or the speed of the bow applied to a string. Pressure variations

 

affect both volume and timbre.

 

 

Embouchure

The tightness of the lips against the reed or against each other.

 

In a string instrument voice Embouchure corresponds to how

 

strongly the bow is pressed against the string. Affects both pitch

 

and timbre.

 

 

Tonguing

Simulates the half-tonguing technique used by saxophone

 

players by changing the “slit” of the reed. The slit is the space

 

between the tip of the reed and the mouthpiece.

 

 

Amplitude

Unlike Pressure, this parameter simply controls the volume of

 

the sound without varying timbre.

 

 

Scream

Drives the entire system into chaotic oscillation, creating effects

 

that can only be achieved with physical modeling technology.

 

 

Breath Noise

Adds breath noise to produce exceptionally realistic effects with

 

many wind instruments.

 

 

Growl

A periodic pressure modulation which produces the “growl”

 

effect often heard in wind instruments.

 

 

Throat Formant

Controls the characteristics of the simulated player’s lungs,

 

trachea, and oral cavity. Can add a realistic “roughness” to the

 

sound. Throat formant only applies to some reed-type voices.

 

 

Filter

Similar to the dynamic filters found in many conventional

 

synthesizers, the cutoff frequency can be varied to produce a

 

wide range of timbral variations. Most voices use the low-pass

 

filter type, but some use the bandpass, high-pass, or band

 

eliminate types. Some voices use very little filter processing at

 

all. Changing the filter settings may not produce a particularly

 

noticeable effect. For detailed filter parameter programming use

 

the VL70-m Expert Editor software (page 25).

Harmonic Enhancer

The Harmonic Enhancer can vary the harmonic structure of the sound over a wide range. Since most VL70-m voices have sufficient natural harmonic content, the Harmonic Enhancer is actually only used on a few voices. Therefore changing the controller destination with many voices will produce either no change in the sound or a simple change in amplitude. For detailed harmonic enhancer programming use the VL70-m Expert Editor software (page 25).

Damping

Simulates the effect of damping due to losses within the body of

 

a wind instrument or in a string due to air friction. Affects both

 

pitch and timbre.

 

 

Absorption

Simulates the effect of high-frequency loss at the end of the air

 

column or string. In the case of a wind instrument, the Damping

 

and Absorption parameters control the diameter and shape of

 

the bell.
