The Breath Parameters
Breath Mode•Settings: BC/WX, Velocity, Touch EG
Sets the control source to be used for “breath” control. This parameter should be set to “BC/WX” when a breath controller or Yamaha WX-series Wind MIDI Controller is being used (page 18). When set to “Velocity”, breath variation is controlled by keyboard initial touch response. When “Touch EG” is selected breath variation is controlled by a combination if initial keyboard touch response and aftertouch pressure. Initial key velocity sets the initial breath level, then aftertouch pressure determines the shape of the subsequent breath envelope.
•The icon of the “Breath Mode”, “Breath Control” and “Breath Setting Lock” parameters indicates which “Breath Mode” parameter setting is selected.
Breath Control•Settings: BC, Exp
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. When “Exp” is selected control change number “11” (expression) is used for breath control. This setting also affects both MIDI and HOST output from the VL70-m.
Breath Curve•Settings: -16 … +16
Determines the relationship between breath control data received from a breath controller, WX-series Wind MIDI Controller, or via the MIDI IN connec- tor, and the actual amount of breath variation applied. Minus settings result in a large breath variation with a relatively small amount of breath pressure applied to the controller, while plus settings required a greater range of input breath control values to produce the same degree of breath variation. The graph at the bottom of the display represents this relationship: the horizontal axis is input breath pressure and the vertical axis is actual breath variation.
Breath Setting Lock•off, on
When this parameters is “off” the VL70-m “Breath Mode” parameter (above) will be automatically set to “BC/WX” whenever a MIDI “XG SYSTEM ON” or “VOICE MODE ON” message is received. At the same the “Breath Control” parameter (above) is set to “BC” and the “Breath Curve” parameter (also above) is set to +00". Turn this parameter “on” if you do not want received MIDI messages to affect the breath setting parameters.
