Playing and Editing VL Voices Virtual Acoustic Synthesis Unlike previous tone generation systems which use oscillators, function generators, 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 computer "models" are used to simulate weather systems or the flight characteristics of aircraft in the design stage, the VL tone generator section simulates the very complex vibrations, resonances, reflections and other acoustic phenomena that occur in a real wind or string instrument. VA Advantages The VL tone generator section offers many advantages in terms of musical performance. Not just in terms of sound, but also in terms of the "behavior" that makes acoustic instruments so ... well, musical! Yamaha Virtual Acoustic Synthesis 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 system. • Simply playing a note 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 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: Controllers (also envelopes) Instrument Modifiers Sound out Guided Tour 63
