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 c

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 mo

Precautions !! PLEASE READ THIS BEFORE PROCEEDING !! Location Do not expose the instrument to the following conditions to avoid deformation, discoloration, or more serious damage. • Direct sunlight (e.g. near a window). • High temperatures (e.g. near a heat source, outside, or in a car during the daytime). • Excessive humidity. • Excessive dust. • Strong vibration. Power Supply • Turn the power switch OFF when the instrument is not in use. • The power adaptor should be unplugged from the AC

Cleaning • Clean the cabinet and panel with a dry soft cloth. • A slightly damp cloth may be used to remove stubborn grime and dirt. • Never use cleaners such as alcohol or thinner. Electrical Interference • This instrument contains digital circuitry and may cause interference if placed too close to radio or television receivers. If this occurs, move the instrument further away from the affected equipment. Data Backup • The VL70-m contains a special long-life battery that retains the conte

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 vibrations, reso- nances, r

The VL70-m Model The overall VL70-m 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 Virtual Acoustic Synthesis 7

The 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 instrument model consists primarily of a driver — the reed/mouthpiece, lip/mouthpiece, or bow/ string system — and a resonant system corresponding to the tube and air column or string. In all these instruments pressure applied here (the driving point) causes vibration which results in sound. NOTES • The sound thus Reed produced is amplified vibra

The Controllers The input to an acoustic wind instrument comes from the player’s lungs, tra- chea, oral cavity, and lips. In a string instrument it comes from the player’s arm movement, transmitted to the string via a bow. These elements actually form an important part of the sound generating system and, in the VL70-m model, are included in the controllers block. The player also influences the sound of the instrument by playing the keys, tone holes, or frets, and this aspect of control constitut

The Modifiers The modifiers block consists of 4 sections as shown in the diagram. Although these may appear to be simple effects, they are actually intimately related to the VL70-m’s sound-producing model and have a significant effect on the sound (the VL70-m has a separate effects stage with reverb, chorus, variation, and distortion effects — see page 86). Harmonic Enhancer The Harmonic Enhancer determines the Harmonic harmonic structure of the sound to the Enhancer extent that it can produce

There’s More … In this brief introduction to VL70-m basics we’ve only looked at the central physical model which is the key the VL70-m’s unprecedented sound and musical performance. There’s actually much more to it. There’s also an exten- sive range of other functions and features that are similar to those you may be familiar with from conventional synthesizers. There are, for example, program- mable envelopes that can be applied to most of the controllers in addition to real-time player control

Setting Up Power Supply Your VL70-m comes supplied with a Yamaha PA-3B AC adaptor. Plug the DC output cable from the AC adaptor into the DC IN jack on the rear panel, then plug the adaptor into a convenient wall AC power socket. It is also a good idea to clip the adaptor’s DC cable into the cable clip on the VL70-m rear panel to minimize the possibility of accidentally unplugging the cable during opera- tion. CAUTION • Do not attempt to use an AC adaptor other than the supplied unit or an appr

MIDI Connections The VL70-m can be used with virtually any type of MIDI controller: key- board, wind controller, sequencer, etc. To ensure reliable error-free transfer of MIDI data always use high-quality MIDI cables obtained from your Yamaha dealer or music equipment store. Also avoid MIDI cables that are longer than about 15 meters, since cables longer than this can pick up noise which can cause data errors. The VL70-m MIDI receive channel and device number parameters are available via the PLA
