Tone Parameters
TVA (Time Variant Amplifier)
TVA
fig.09-40(LCD_TvaTva)
Level
Sets the volume of a Partial. Higher values may cause sound
distortion. If so, lower the value. Even when the Level is set to
zero here, the sound may not be completely muted if the TVA
ENV curve is high.
Value: 0–100
Velo (Velocity Range)
Sets the sensitivity of the velocity that controls the volume of the
sound. "-" values lower the level by harder playing, and "+"
values raise the level by harder playing.
Value: -50–+50
BP (Bias Point)
You can change the overall volume of the keyboard (= bias level) from the set level, and set the range (bias
direction) where the bias level is valid.
This bias range is where the bias level is valid on the keyboard. It can be set with the bias point (Where he
bias range begins) and bias direction ( < or > ).
Value: <A1–<C7, >A1–>C7
Display Example
>C4
<C4
BLevel (Bias Level)
The curve ( bias level ) can be set. Lower values make the curve steeper.
Value: -12–0
