The VL1-m Model

he overall VL1-m model or "algorithm" consists of three main

blocks: the instrument, controllers, and modifiers. In schematic

form these blocks are arranged as follows:

One VL "Element"

Controllers (also envelopes)

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. The extreme complexity

of this portion of the model makes it unsuitable for user programming, so vari-

ous instruments for the VL1-m are provided in the form of pre-programmed

voices. These are primarily woodwind, brass, and string voices, since the VL1-

m's physical model is capable of most accurately simulating the sound-generat-

ing mechanism of all three instrument categories.

The instrument model consists primarily of a driver — the reed/mouth-

piece, lip/mouthpiece, or bow/string system — and a resonant system corre-

sponding to the tube and air column or string.
