Changing the Volume and Stereo Location ([F4 (TVA)])
The TVA (Time Variant Amplifier) controls volume changes
to the Tone as well as its stereo positioning.

TVA

Level (Tone Level)

Range: 0–127
Sets the volume of the Tone. This setting is useful primarily
for adjusting the volume balance between Tones.
The overall volume of the Patch is set by the Level (PATCH
Common General page) setting, raising or lowering the Tone
level settings of its individual Tones by the selected amount.
(p. 127)

V-Curve (TVA Level Velocity Curve)

Range: FIXED/1–7
This setting allows you to select from seven velocity curves
that determine how the force with which the keyboard is
played is to affect the Tone’s volume. The selected curve is
displayed to the below of its parameter value.
When set to “FIXED,” the Tone’s volume will not be affected
by the force with which the keyboard is played.

V-Sens (TVA Level Velocity Sens)

Range: -63– +63
Use this setting when you want keyboard touch (velocity) to
affect the Tone volume. Set this to a positive value to have
the changes in tone volume increase the more forcefully the
keys are played; to make the Tone play more softly as you
play harder, set this to a negative value.

Bias

Use the Bias parameter when you want the position of notes
on a keyboard to affect the TVA level.
fig.04-047.e

Level (TVA Bias Level)

Range: -100– +100
Adjusts the slope of the volume change that will occur in the
selected Bias Direction. Higher values will cause greater
change. Negative (-) values invert the change.

Position (TVA Bias Position)

Range: C -1–G9
Selects the MIDI key at which the Tone’s volume will begin
to change.

Direction (TVA Bias Direction)

This determines whether the volume of notes above or below
the Bias point — or both — will change according to their
distance from the Bias Point.
Available Settings:
LOWER: Notes below the Bias Point will be affected.
UPPER: Notes above the Bias Point will be affected.
LOWER&UPPER: Notes below and above the Bias Point will
be affected.
ALL: The volume of notes across the entire keyboard will be
biased according to the Bias Level slope, based on their
distance from the Bias Point.

Pan (TVA Pan)

Use these parameters to dynamically alter the Tone’s stereo
position as set by the TVA Pan.

Pan (Tone Pan)

Range: L64–0–63R
Specifies the stereo position of the Tone. L64 is far left, 0 is
center, and 63R is far right.
The overall panning of the entire Patch is set by the Pan
parameter (Patch Common General page), and the Pan (Tone
Pan) setting is added to this setting. (p. 127)
