Thank you for choosing a Yamaha VL70-m Virtual Acoustic Tone Generator. The VL70-m is a monophonic tone generator incorporating 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 new dimension to your sound … whether you play a keyboard, wind controller, MIDI guitar synthesizer, or use a sequencer to create music.

Please read this owner’s manual carefully, and follow the instructions within in order to ensure proper operation. Also keep this manual in a safe place for later reference.

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 attempting to edit and modify voices. We urge you to read the following section of this manual — “Virtual Acoustic Synthesis — before getting into the details. It will make a huge difference in how quickly you understand the VL70-m system, and how efficiently you will be able to edit voices to create the sound you’re looking for.

Other than the above, the structure of the manual is fairly straightforward. You can approach it in a “linear” manner, reading through from beginning to end, or on an “on demand” basis, going directly to the information you need as you need it. Use the table of contents at the beginning, and the index at the end of the manual to find the information you need.

Conventions

The following conventions are used through the VL70-m manuals to avoid confusion and make the text easier to read.

■ Buttons & Controls

Button and control names used on the VL70-m panel appear in the text in capital letters within square brackets: “the [ENTER] button”, for example.

■ Parameter Ranges

An ellipsis is used to indicate a range of parameter values: e.g. “0 … 127”. This minimizes the confusion sometimes caused by the use of a hyphen or dash for this purpose.

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 outlet if the instrument is not to be used for an extended period of time.

•Unplug the instrument during electric storms.

•Avoid plugging the instrument into the same AC outlet as appliances with high power consumption, such as electric heaters or ovens. Also avoid using multi-plug adaptors since these can result in reduced sound quality and possibly damage.

■ Turn Power OFF When Making Connections

• To avoid damage to the instrument and other devices to which it is connected (a sound system, for example), turn the power switches of all related devices OFF prior to connecting or disconnecting audio and MIDI cables.

■ MIDI Connections

• When connecting the VL70-m to MIDI equipment, be sure to use highquality cables made especially for MIDI data transmission.

• Avoid MIDI cables longer than about 15 meters. Longer cables can pick up electrical noise that can causes data errors.

■ Handling and Transport

•Never apply excessive force to the controls, connectors or other parts of the instrument.

•Always unplug cables by gripping the plug firmly, not by pulling on the cable.

•Disconnect all cables before moving the instrument.

•Physical shocks caused by dropping, bumping, or placing heavy objects on the instrument can result in scratches and more serious damage.

4 Precautions

■ 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 contents of its internal memory even when the power is turned OFF. The backup battery should last for several years. When the backup battery needs to be replaced “Battery Low!” will appear on the display when the power is turned on. When this happens, have the backup battery replaced by qualified Yamaha service personnel. DO NOT ATTEMPT TO REPLACE THE BACKUP BATTERY YOURSELF!

■ Service and Modification

• The VL70-m contains no user serviceable parts. Opening it or tampering with it in any way can lead to irreparable damage and possibly electric shock. Refer all servicing to qualified YAMAHA personnel.

■ Third-party Software

•Yamaha can not take any responsibility for software produced for this product by third-party manufacturers. Please direct any questions or comments about such software to the manufacturer or their agents.

YAMAHA is not responsible for damage caused by improper handling or operation.

Precautions 5

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 VL70-m simulates the very complex vibrations, resonances, reflections and other acoustic phenomena that occur in a real wind or string instrument.

VA Advantages

The VL70-m 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 VL70-m 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.

6 Virtual Acoustic Synthesis

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.

■ NOTES

•The sound thus produced is amplified and sustained by the body of the instrument.

•The pitch of the sound is determined by the length of the air column or string, and the timbre is a complex product of the driving source (reed, lip, air, string), the shape of the resonant cavity, the materials from which the instrument is made, etc.

In all these instruments pressure applied here (the driving point) causes vibration which results in sound.

Reed vibration

Lip vibration

Air vibration

String vibration

One of the remarkable features of the VL70-m’s Virtual Acoustic Synthesis system is that just about any driver can be used with any type of pipe or string.

Pipes/String

8 Virtual Acoustic Synthesis

The Controllers

The input to an acoustic wind instrument comes from the player’s lungs, trachea, 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 constitutes another part of the controllers block. These and other control parameters provided by the VL70-m are listed in the illustration below.

In essence, the controller parameters determine how the instrument “plays”. All of these parameters can be assigned to any external controller that can be used with the VL70-m: breath controller, foot controller, modulation wheel, etc. The pressure parameter, for example, will normally be assigned to a breath controller so the player can control the dynamics of the instrument by varying the breath pressure applied to the controller — a natural, instinctive way to play windinstrument voices. At the same time the growl and throat parameters might also be assigned to the breath controller in order to achieve life-like response and effects.

Embouchure

The tightness of the lips against the reed or against each other, or the force of the bow against the string.

Tonguing

Simulates the halftonguing technique used by saxophone players by changing the “slit” of the reed.

Pitch

Changes the length of the air column or string, and thereby the pitch of the sound.

Damping & Absorption

Simulate the effects of air friction in the pipe or on the string, and of high-frequency losses at the end of the pipe or string.

Throat

Controls the characteristics of the “player’s” throat or bowing arm.

Pressure

The amount of breath pressure applied to the reed or mouthpiece, or bow velocity applied to the string.

Growl

A periodic pressure (bow velocity) modulation which produces the “growl” effect often heard in wind instruments.

Scream

Drives the entire system into chaotic oscillation, creating effects that can only be achieved with physical modelling technology.

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 structure of the sound to the extent that it can produce radical timbral variations within an instrument “family” (e.g. saxes). The harmonic enhancer parameters can be accessed via the Yamaha VL70- m Expert Editor software (page 25).

● Dynamic Filter

This section is similar to the dynamic filters found in many conventional synthesizers, with high-pass, bandpass, band elimination, and low-pass modes. Some filter parameters are available via the VL70-m controls, but detailed editing of parameters such as the filter type requires the Yamaha VL70-m Expert Editor software (page 25)

● Frequency Equalizer

Equalizer

Resonator

This is a 5-band parametric equalizer with frequency, Q (bandwidth), and level control. The equalizer also has pre-EQ highand low-pass filters as well as key scaling capability for precise response control throughout the instrument’s range. Although only simplified treble and bass parameters are available via the VL70-m controls, the full range of equalizer parameters can be accessed via the Yamaha VL70-m Expert Editor software (page 25).

● Resonator

The Resonator uses simulated “resonator” pipes or strings and delays to produce a “woody” resonance effect — although it has little or no effect on some voices. The resonator parameters can be accessed via the Yamaha VL70-m Expert Editor software (page 25).

10 Virtual Acoustic Synthesis

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 extensive range of other functions and features that are similar to those you may be familiar with from conventional synthesizers. There are, for example, programmable envelopes that can be applied to most of the controllers in addition to real-time player control. And, of course, there’s a comprehensive selection of utility functions that give the VL70-m maximum versatility and convenience. Now that you understand the basics, dive in and find out what the VL70-m can really do.

@0MIDI IN, OUT and THRU Connectors

The MIDI IN connector receives the data from an external sequencer or other MIDI device which is to control or transmit data to the VL70- m. The MIDI THRU connector simply retransmits the data received at the MIDI IN connector, allowing convenient chaining of MIDI devices. The MIDI OUT connector transmits data corresponding to VL70-m Breath Controller operation, or bulk data when one of the MIDI data transmission functions are activated. The MIDI OUT connector can also be used to “echo” (re-transmit) data received via the MIDI IN or TO HOST connectors.

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 operation.

■ CAUTION

•Do not attempt to use an AC adaptor other than the supplied unit or an appropriate replacement provided by your Yamaha dealer to power the VL70-m. The use of an incompatible adaptor may cause irreparable damage to the VL70-m, and might pose a serious shock hazard!

•Be sure to unplug the AC adaptor from the AC mains socket when the VL70-m is not in use.

MIDI Connections

The VL70-m can be used with virtually any type of MIDI controller: keyboard, 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 PLAY mode display and PLAY mode sub-control display (pages 32 and 34). Make sure these parameters are set to match the corresponding settings of the MIDI controller used with the VL70-m.

● The VL70-m receives the following MIDI data:

Note	The played note and velocity values.
Control Change	Modulation wheel, breath controller, foot controller, sustain, and
	other controller data.
Aftertouch	Keyboard aftertouch pressure (channel aftertouch only).
Pitch Bend	Pitch bend wheel position.

Program Change Voice numbers and bank select messages.

& Bank Select

System Exclusive Voice and system data transmitted in the form of “bulk dumps.”

■ NOTES

•IMPORTANT!: The rear-panel HOST SELECT switch must be set to “MIDI” when the VL70- m is not connected to a computer via the TO HOST connector.

•For detailed MIDI specifications refer to the “MIDI Data Format” on page 26 of the List Book.

•When using the VL70-m with other MIDI equipment, it is a good idea to refer to the MIDI specifications (implementation chart, MIDI data format) of the equipment used to ensure compatibility.

16 Setting Up

Breath Controller

If you will be using the VL70-m with a keyboard, a breath controller is an essential expressive tool — both for realistic expression with wind-instru- ment voices and unprecedented expressive control with string voices. Plug an

optional Yamaha BC3, BC2 or BC1 Breath Controller into the front-panel breath controller jack. If the controlling MIDI keyboard has a breath controller jack, it might be more convenient to plug the breath contoller in there rather than directly into the VL70-m. The Breath Controller is ideal for controlling parameters that would normally be affected by a wind player’s breath: dynamics, timbre, pitch, and others.

■ IMPORTANT!

•If you will be using a BC3, BC2, or BC1 breath controller plugged into the BREATH jack, the “Breath Mode” parameter must be set to “BC/WX” (page 96). This is also necessary if you plug the breath controller into the keyboard’s breath controller jack.

VL70-m

Special care must be taken with the following parameters and controls when using a WX-series Wind MIDI Controller:

■ NOTES

•If a WX controller is unplugged while the VL70-m power is on, the breath level may remain fixed at “0” and subsequently played notes may not sound. If this happens, turn the VL70-m power off and then on again.

BREATH MODE The Breath Mode parameter (page 96) must be set to “BC/WX” in order for the VL70-m to recognize breath data from the controller.

SOUND MODULE If you intend to drive additional MIDI devices via the VL70-m MODE MIDI OUT connector when using a Wind MIDI Controller, the

VL70-m sound module mode should be set to VOICE (page 29). When the VL-XG mode is selected MIDI note data received via the MIDI IN connector is not re-transmitted via the MIDI OUT connector.

LIP MODE	WX-series Wind MIDI Controllers produce pitch bend data
	ranging from “-16” to “+32” in response to lip (reed) pressure.
	The WX Lip parameter (page 98) determines whether these
	values are used as is (“Norm”), or expanded to a “-64” through
	“+63” range (“Expd”). When the “Expd” mode is selected, the
	expanded pitch bend data is also transmitted via the MIDI OUT
	connector. The “Expd” setting is recommended when using a
	WX controller in the “tight lip” mode. The “Norm” setting is
	recommended when using the WX controller “loose lip” mode.
MIDI/WX	When the VL70-m is connected to a WX controller and a
SETTING	computer via the TO HOST connector, and the HOST SELECT
	switch is set to any position other than “MIDI”, the front-panel
	[MIDI/WX] button must be used to select the “WX” mode (a
	small WX icon will appear on the left side of the display) in
	order for the VL70-m to recognize data from the WX controller.
	When the HOST SELECT switch is set to “MIDI” the VL70-m
	accepts both MIDI and WX data (both the MIDI and WX icons
	appear on the display), and the [MIDI/WX] button has no effect.

Audio Connections

■ Headphones

For private listening and practice headphones are ideal. You don’t have to hook up and complete sound system, and you won’t disturb the neighbors no matter how loud or late you play. Any standard pair of stereo headphones with a stereo mini phone plug and an impedance of between about 8 and 150 ohms can be used.

■ Stereo Sound System

The VL70-m voices and effects are designed to sound their best in stereo, so you should always use a stereo sound system to appreciate the full impact of the VL70-m voices and expressive features. The VL70-m OUTPUT L/MONO and R jacks can be connected directly to musical instrument amplifiers designed for keyboard use, or to the line inputs of a mixing console. It is also possible to connect the VL70-m outputs directly to the inputs of a multitrack or stereo tape recorder.

■ NOTES

•If you need to drive a mono amp or other device, connect only the L/MONO output jack. The left and right channel signals are automatically combined and delivered via the L/ MONO jack when a single phone plug is inserted in this jack and the R output jack is left unconnected.

•Make sure that both the VL70-m and your sound system are turned OFF when making connections.

22 Setting Up

Power-on Procedure

Always follow proper procedure when powering-up a sound system to minimize the possibility of damage to the equipment (and your ears!).

1.Make sure your sound system’s main level/volume control(s) and the VL70-m volume control are turned all the way down prior to turning power on.

2.Turn on the VL70-m.

3.Turn on your MIDI controller (and computer/sequencer, if used).

4.Turn on the sound system.

5.Raise the sound system volume to a reasonable level.

6.Gradually raise the VL70-m VOLUME control while playing the MIDI controller to set the desired listening level.

■ NOTES

•Some keyboards and other MIDI controllers automatically transmit MIDI control change data corresponding to their control status when the power switch is turned ON or OFF. The VL70-m is programmed to receive this data and respond accordingly, so it is preferable to turn the VL70-m ON before turning the controlling device ON.

Setting Up 23

Play the Demo

Once you’ve set up your VL70-m system, you might like to play the preprogrammed demo sequence to hear how some of the voices sound. This process will also help to familiarize you with some of the VL70-m’s selection

and editing procedures.

■ NOTES

•When the demo is played all system setup parameters and current voice are initialized. If your VL70-m memory contains data you want to keep, be sure to use the bulk dump function (page 100) to save the data to an external MIDI data recorder or other appropriate storage device before playing the demo.

The Supplied Demo Disk

The VL70-m is supplied with a demonstration data disk which contains several songs which demonstrate some of the VL70-m’s advanced musical

capabilities. The songs on this disk can be reproduced using any sequencer or computer-based sequence software which can handle SMF (Standard MIDI File

— format 0) song files.

All of the demo songs use the VL70-m for the main melody line, while a second XG tone generator (Yamaha MU50 or MU80 for example) supplies the backing.

■ NOTES

•The supplied disk is a 2DD type (720 kilobytes) using MS-DOS format. The disk can be read by Macintosh computers by using the PC Exchange application and an application such as ResEdit which can change the file’s file type.

The VL70-m Voice Editing Software

— What It Is & Where To Get It —

The range of parameters accessible via the VL70-m programming interface is limited to the simplest “upper level” of virtual acoustic synthesis parameters. The “core” parameters which are the true foundation of physical modeling are extremely complex, and were therefore not made directly accessible.

The VL70-m Expert Editor voice editing software provides full access to the complete range of physical modeling parameters. It can be used alone to create new voices, or edit voices loaded from the VL70-m. The VL70-m Expert Editor is basically a refined version of the editing software Yamaha voicing professionals use to create original voices for VL-series synthesizers and tone generators. It therefore gives you full professional-level programming power and potential. Another handy VL editing software is the VL Visual Editor. The VL Visual Editor makes it easy for anyone to create new VL voices via a graphic, easy-to- use editing interface. The VL70-m Expert Editor can read voice files created by the VL Visual Editor, allowing further in-depth programming.

The VL Voice Editing Software can be obtained via Yamaha’s XG

home page on the World Wide Web, “http://www.yamaha.co.jp./english/xg/html/ libhm.html”.

Voice Organization and Sound Module

Modes

Voice Organization

The VL70-m voices are organized into four main banks. Additional banks are used when the VL70-m is set to operate in the VL-XG sound module

mode (page 29). The four main banks are as follows:

	PRESET 1	The PRESET 1 bank contains 128 preset voices which have been
		created primarily to be played via a keyboard.
	PRESET 2	The PRESET 2 bank contains 128 preset voices which have been
		created to provide maximum expressive capability when played
		with a breath controller or WX-series Wind MIDI Controller.
	CUSTOM	The CUSTOM bank has 6 memory locations in which voices can
		be edited in detail via an appropriate personal computer and
		the Yamaha VL70-m Expert Editor application software (page
		25). When the VL70-m is initially shipped CUSTOM voice num-
		bers 001 through 006 contain a selection of sound-effect type
		voices from the PRESET banks.
	INTERNAL	The INTERNAL bank has 64 memory locations in which voices
		you have edited can be stored and easy recalled for use as
		required. Unlike CUSTOM voices, INTERNAL voices can be edited
		via the VL70-m panel controls. When the VL70-m is initially
		shipped INTERNAL voice numbers 001 through 064 contain a
		selection of voices from the PRESET 1 and PRESET 2 banks, set
		up to be played via a WX-series Wind MIDI Controller.

Banks 112 through 119 become available when the VL70-m is set to the VL-XG sound module mode (page 29). In the VL-XG sound module mode some voices from the PRESET 1 and PRESET 2 banks are assigned MIDI bank and program change numbers conforming to the Yamaha XG format. Since the VL70-m does not have a full set of XG-compatible voices, however, some voice numbers will be skipped (e.g. 23, 24, 27, etc.).

■ NOTES

• PRESET 1, PRESET 2, and CUSTOM voices can be edited via the VL70-m panel controls, but the edited voices cannot be stored to the PRESET 1, PRESET 2, or CUSTOM bank. Edited voices can only be stored to the INTERNAL bank, and only when the VL70-m is set to the VOICE sound module mode (page 29).
