Playing and Editing VL Voices
Virtual Acoustic Synthesis
Unlike previous tone generation systems which use oscillators, function gen-
erators, preset waveforms or samples to produce sound, Yamaha Virtual
Acoustic (“VA”) Synthesis applies sophisticated computer-based “physical
modeling” technology to musical sound synthesis. In the same way that com-
puter “models” are used to simulate weather systems or the flight character-
istics of aircraft in the design stage, the VL tone generator section simulates
the very complex vibrations, resonances, reflections and other acoustic phe-
nomena that occur in a real wind or string instrument.
VA Advantages
The VL tone generator section offers many advantages in terms of musical per-
formance. Not just in terms of sound, but also in terms of the “behavior” that
makes acoustic instruments so … well, musical! Yamaha Virtual Acoustic Syn-
thesis is simply the most musical tone generation system ever created.
• The VL tone generator section sounds better, has more depth, and is
more realistic in the musical sense than any other tone generation sys-
tem.
• Simply playing a note in the same way does not always produce pre-
cisely 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 mu-
sically as the notes themselves.
• It has extraordinary expressive capability. Rather than simply control-
ling parameters like volume or pitch, you can control characteristics
such as breath and reed pressure with appropriate complex effects on the
timbre of the sound.
VL Tone Generator Model
The overall VL Tone Generator model or “algorithm” consists of three main
blocks: the instrument, controllers, and modifiers. In schematic form these
blocks are arranged as follows:
Sound out
Controllers (also envelopes)
Instrument Modifiers
