BIAS
Use the Bias parameter when you want keyboard position to
affect the TVA level.

Bias (Bias Level)
Adjust the angle of the volume change that will occur in the
selected Bias Direction. Higher settings will result in greater
change. Negative (-) values will invert the change.
Point (Bias Point)
Select the key at which the volume will begin to change.
Direction (Bias Direction)
Select the direction in which change will occur starting from
the Bias Point.
LOWER: the range below the Bias Point
UPPER:
the range above the Bias Point
LOWER&UPPER: the ranges both above and below the Bias
Point
ALL:
the entire keyboard will be biased at the
angle determined by the Bias Level,
relative to the Bias Point

Use these parameters to affect the location of the TVA Pan.
Keyfollow (Pan Key Follow)
Use this parameter when you want the keyboard position to
change the stereo location. Higher values will result in
greater change relative to middle C (C4). Positive (+) settings
will cause notes played toward the right of the keyboard to
be panned right. Negative (-) settings will cause the opposite.
Random (Random Pan Depth)
Use this parameter when you want the stereo location to
change randomly each time you press a key. Higher values
will result in a greater width of change.
Alternate (Alternate Pan Depth)
Use this parameter when you want the stereo location to
alternate between left and right each time you press a key.
Higher values will result in a greater width of change.

L or R values can be set, and this will reverse the left/right
order of the panning. If you want to alternate the pan
position of two Tones, set them to opposite L and R settings.
TVA TIME ENV (TVA Time Envelope)
These parameters determine how the keyboard will affect the
time changes of the TVA envelope.
V-T1 (TVF Envelope Time 1 Velocity Sensitivity)
Use this parameter when you want velocity to affect T1
(time) of the TVA envelope. Higher settings will result in a
greater difference between strongly and softly played notes.
If you want higher velocities to speed up T1 time, use
positive (+) values. If you want higher velocities to slow
down T1 time, use negative (-) values.
V-T4 (TVA Envelope Time 4 Velocity Sensitivity)
Use this parameter when you want Key Off Velocity (the
speed at which you release a key) to affect T4 (time) of the
TVA envelope. Higher settings will result in a greater
difference between quickly and slowly released notes. If you
want a quicker release to speed up the T4 time, use positive
(+) settings. If you want a quicker release to slow down the
T4 time, use negative (-) settings.
Time Keyfollow (TVA Envelope Time Key Follow)
Use this parameter when you want keyboard position to
affect TVA envelope times (T2–T4). Higher values will result
in a greater change relative to middle C (C4). Positive (+)
settings will result in shorter times as you play toward the
right of the keyboard. Negative (-) settings will result in
longer times as you play toward the right of the keyboard.
TVA ENVELOPE (TVA Envelope)
These parameters make settings for the TVA envelope
(changes over time in the TVA level).

TVA level.
