  • Page 4 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.

    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.

  • Page 98: The Distortion Parameters

    The Distortion Parameters Distortion is an excellent way to drastically change a sound — although subtle distortion settings can produce surprisingly delicate variations. Type • Distortion Type • Settings: THRU, DISTORTION, OVERDRIVE, 3-BAND EQ Selects the distortion type, or “THRU” if no distortion effect is required.

  • Page 99: Breath Settings

    Breath Settings The Breath Setting includes a number of setting that determine how the VL70- m responds to breath control from a breath controller, a Yamaha WX-series Wind MIDI controller, or MIDI. Accessing & Editing the Breath Parameters The BREATH parameters can be accessed and edited from the PLAY mode as follows: 1.

  • Page 100: The Breath Parameters

    Specifies the MIDI control change number to be used for breath control when breath control is applied from a breath controller, WX-series Wind MIDI Controller, or via the VL70-m MIDI IN connector. When “BC” is selected control change number “02” (breath control) is used for breath copntrol.

  • Page 101: The Utility Mode

    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 PLAY mode by pressing the [UTILITY] button.

    M.Tune • Master Tuning • 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). The maximum minus and plus settings produce a downward or upward pitch shift of just over a semitone.
  • Page 103 • When the VL-XG sound module mode is selected and a program change number correspond- ing to a VL70-m voice is received, the “NoteFilter” parameter is automatically set to the channel on which the program change number was received. This does not occur in the VOICE sound module mode.

  • Page 104: 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 Yamaha MDF2 MIDI Data Filer via the MID OUT or TO HOST connec- tor.

  • Page 106: The Initialize Function

    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. “System Initialize” restores all system setup parameters (page 98) to their default settings.

    Press the [EXIT] button to return to the previous display. With the VL70-m it is possible to control just about any parameter via MIDI system exclusive messages from an external MIDI device. This makes it possibe, for example, to change filter or EG settings while playing, to change the sound as required.

  • Page 108: The Message Window

    The VL70-m Message Window function makes it possible to display text messages up to 32 characters in length on the VL70-m display in the PLAY 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.

  • Page 109: Bitmap Window

    Bitmap Window The VL70-m Bitmap Window function makes it possible to display 16 x 16 dot icons and simple animation sequences on the VL70-m display in the PLAY 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.

  • Page 111: Troubleshooting

    The VL70-m is a very versatile tone generator with many features and functions that affect operation. In many cases, what appears to be a fault with the VL70-m can actually be traced to an improperly set parameter or something as simple as a bad connection.

    Answers to Some Com- mon Questions 1. The VL70-m is a monophonic tone generator. 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.
