6 V irtual Acoustic Synthesis Virtual Acoustic Synthesis Unlike previous tone generation systems which use oscillators, function genera- tors, preset waveforms or samples to produce sound, Y amaha V irtual Acoustic (“V A”) Synthesis applies sophisticated computer-based “physical modeling” technology to musical sound synthesis.
7 Virtual Acoustic Synthesis Controllers (also envelopes) Instrument Modifiers Sound out The VL70-m Model The overall VL70-m model or “algorithm” consists of three main blocks: the instrument, controllers, and modifiers.
8 Virtual Acoustic Synthesis ■ 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.
9 Virtual Acoustic Synthesis 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 .
10 The Modifiers Virtual Acoustic Synthesis 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 .
11 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.

90 The Reverb P ar ameters The reverb effects are essential to give your sound ambience and a sense of dimension, adding warmth and depth to an otherwise dry sound.
91 The Chorus P ar ameters The VL70-m chorus stage actually includes a number of modulation-type ef fects that can be used to give your sound extra animation and life.
92 The V ariation P arameters The variation stage includes reverb, delay , echo, modulation, distortion, wah, and a range of other effects. T ype • V ariation T ype • Settings: NO EFFECT , HALL 1,.
93 higher the value, the more variation signal is sent to the chorus stage. If this parameter and the PLA Y mode “V arRtn” parameter are both set to values higher than “001”, the output of the variation stage will be sent in corresponding amounts to the input of the chorus stage and the main outputs.
94 The Distortion P ar ameters Distortion is an excellent way to drastically change a sound — although subtle distortion settings can produce surprisingly delicate variations. T ype • Distortion T ype • Settings: THRU, DISTORTION, OVERDRIVE, 3-BAND EQ Selects the distortion type, or “THRU” if no distortion effect is required.
95 Breath Settings Br eath Settings The Breath Setting includes a number of setting that determine how the VL70- m responds to breath control from a breath controller , a Y amaha WX-series W ind MIDI controller , or MIDI.
96 The Breath P arameter s Breath Mode • Settings: BC/WX, Velocity , T ouch EG Sets the control source to be used for “breath” control. This parameter should be set to “BC/WX” when a breath controller or Y amaha WX-series W ind MIDI Controller is being used (page 18).
97 The Utility Mode The UTILITY mode provides access to a range of parameters that affect basic operation of the VL70-m, and some functions that contribute to system flexibil- ity . Select the UTILITY sub-mode menu from the PLA Y mode by pressing the [UTILITY] button.
98 The System P ar ameters The UTILITY SYSTEM sub-mode includes parameters that affect overall operation of the VL70- m. M.T une • Master T uning • Settings: -102.4c … +102.3c Fine tunes the overall pitch of the VL70-m in 0.1- cent steps (a “cent” is 1/100th of a semitone).
99 Contrast • Display Contrast • Settings: 1 … 8 Sets the contrast of the VL70-m display for optimum visibility . The best setting will depend on your viewing angle and the ambient lighting conditions. A setting of “1” produces the strongest contrast, while a setting of “8” produces the “softest” contrast.
100 The Dump Out Function The Dump Out function allows VL70-m setup and system exclusive data to be transmitted to a second VL70-m or an external MIDI storage device such as the Y amaha MDF2 MIDI Data Filer via the MID OUT or TO HOST connec- tor .
101 2. Press [ENTER] Press the [ENTER] button to go to the confirmation/select display for the selected data type. 3. Select “ ALL ” or a Single V oice for CUST OM or INTERNL If you have selected .
102 The Initialize Function The VL70-m Initialize function includes two sub-modes — “Factory Set” and “System Initialize”. “Factory Set” initialization restores all VL70-m data to the initial factory settings … including all Custom and Internal voices.
103 Appendix Appendix Show Control Change This function displays the MIDI control change data string required to control the parameter currently displayed in the PLA Y mode from an external MIDI device. The MIDI data is displayed in hexadecimal format.
104 The Message Window The VL70-m Message W indow function makes it possible to display text messages up to 32 characters in length on the VL70-m display in the PLA Y mode. The messages can be transmitted in the form of a data string from an external MIDI device, and will appear on the VL70-m display for about 3 seconds.
105 Bitmap W indow The VL70-m Bitmap W indow function makes it possible to display 16 x 16 dot icons and simple animation sequences on the VL70-m display in the PLA Y mode. The bitmap data can be transmitted in the form of a data string from an external MIDI device, and will appear on the VL70-m display for about 3 seconds.
106 After converting all 48 rows in the example we have the following hexadecimal bytes: Checksum Some VL70-m system exclusive message require a “checksum” — a data byte which is used to check for errors during MIDI data transfer . The checksum is calculated using the system exclusive message start address and data (data size).
107 2. Add all the converted numbers. 3. Divide the total by 128 and note the remain- der . 4. Subtract the remainder from 128. The result is the checksum.
108 Symptom • No sound. P ossible Causes • Is the amplifier/mixer power turned on? • Is the amplifier/mixer volume set to an appro- priate level? • Is the VL70-m volume control set to an appro.
109 Symptom • No effects. P ossible Causes • Are the effect send levels set properly (pages 35 and 39)? • Are the effect return levels set properly (pages 32, 33 and 41)? • Is “NO EFFECT” .
110 Answer s to Some Com- mon Questions 1. The VL70-m is a monophonic tone gener ator . Why is the “poly” mode initialy selected when the VL-XG sound module mode is engaged? This is to provide compatibility between the currrent XG format and future polyphonic VL- series tone generators.
111 6. Why do some bowed string instrument voices tend to “squeek”? As anyone who has played (or tried to play) a real violin knows, these instruments naturally tend to squeek if not properly controlled.
112 Error Messages When an operational error or other problem occurs, the VL70-m will display one of the following error messages to inform you of the problem. Battery Low! The internal backup battery needs to be replaced. Have the battery replaced by qualified Y amaha service personnel.
