Patch Edit
Amp
These TVA (Time Variant Amplifier) parameters specify how the volume and pan of the sound will change.
Parameter Value Description
Patch Level # 0–127 Volume of the entire patch
Tone Level 0–127 Volume of each tone
This parameter is used mainly to adjust the volume balance between tones.
BIAS
Use the Bias parameter when you want the position of notes on a keyboard to affect the TVA level.
Bias Level -100– +100 Angle at which the volume will change relative to the bias direction
Increasing this value will produce a greater change. Negative (-) values will invert the direction of the
change.
Bias Position 0–127 Selects the note number relative to which the volume will change.
Bias Direction LWR, UPR,
L&U, ALL Direction of change relative to the bias point
LWR: Notes below the bias point
UPR: Notes above the bias point
L&U: Notes to the left and right of the bias point
ALL: Bias level varies the angle relative to the bias point
Tone Pan L64–63R Pan of each tone
L64 is far left, 0 is center, and 63R is far right.
Pan Keyfollow
(Tone Pan Keyfol-
low) -100– +100 Set this parameter if you want the pan to be affected by the note you play.
Increasing this value will produce a greater change relative to middle C (C4). Positive (+) values will
cause the pan to move toward the right as you play toward the right. Conversely, negative (-) values
will adjust pan toward the right.
Random Pan Depth
(Tone Random Pan
Depth) 0–63 Amount by which the pan will be varied randomly each time you play a note
Increasing this value will produce a greater amount of random change.
Alter Pan Depth
(Tone Alternate Pan
Depth) L63–63R Amount by which the pan will be moved alternately between left and right each time you play a note
Increasing this value will produce a greater amount of change. This value can be adjusted in the L or
R direction, and these will invert the order in which the tone is panned to left and right. If you want
two tones to alternate between left and right, set each tone to opposite L and R values.
