Thank you for choosing a Yamaha VL70-m Virtual Acoustic
Tone Generator. The VL70-m is a monophonic tone generator incor-
porating Yamaha’s revolutionary “Virtual Acoustic Synthesis” tone
generation system — based on the most advanced computer physical
modeling technology. Virtual Acoustic Synthesis produces sound that
is more realistic, more expressive, and more musical than any other
system available at this time. The VL70-m includes 256 preset
voices, from super-realistic to innovative, that can add a...

About the Manual
The VL70-m is a very unique tone generator that operates on totally new
principles that were simply unheard of until Yamaha released the worlds first
“Virtual Acoustic” synthesizer based on computer physical modelling. If you’ve
had some experience with the Yamaha VL1, VL1-m, VL-7, or their “Version 2”
upgrades, you will have very little trouble understanding the VL70-m. If you are
new to VA synthesis, however, you will need a little background before attempt-
ing to edit and modify...

Virtual Acoustic Synthesis
Virtual Acoustic Synthesis
Unlike previous tone generation systems which use oscillators, function genera-
tors, 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 VL70-m simulates the very complex...
