Roland VC-1 D-50 TVA Time Variant Amplifier, Value -50-+50 BP Bias Point, Value Volume Adjustment

Tone Parameters

TVA (Time Variant Amplifier)

TVA

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	Function Example
>C4	The bias level is only valid on the keyboard above the C4 key.
<C4	The bias level is only valid on the keyboard below the C4 key.

BLevel (Bias Level)

The curve ( bias level ) can be set. Lower values make the curve steeper.

Value: -12–0
