V-Curve (TVA Envelope Velocity Curve)

Selects one of the following seven curves to specify how keyboard dynamics will affect the TVA envelope. Set this to FIXED when the amount of TVA Envelope applied is not to be changed according to the force with which the keys are pressed.

BIAS

Bias causes the volume to be affected by the keyboard position. This is useful for changing volume through keyboard position (pitch) when playing acoustic instruments.

	LOWER					UPPER
Level		+			Level					+
		0			Key					0	Key
		–								–
	C-1		Bias Point		G9		C-1		Bias Point		G9
	LOWER&UPPER						ALL

		0		0				0		0
		–		–	Key			+		–	Key
	C-1		Bias Point		G9		C-1		Bias Point		G9

Bias (Bias Level)

Adjusts the angle of the volume change that will occur in the selected Bias Direction. Higher values will result in more change. Negative (-) values will invert the change direction.

Point (Bias Point)

Specifies the key relative to which the volume will be modified.

Direction (Bias Direction)

Selects the direction in which change will occur starting from the Bias Point.

LOWER: The volume will be modified for the keyboard area below the Bias Point.

UPPER: The volume will be modified for the keyboard area above the Bias Point.

LOWER&UPPER: The volume will be modified symmetrically toward the left and right of the Bias Point. ALL: The volume changes linearly with the bias point at the

center.

PAN MODULATE

Keyfollow (Pan Keyfollow)

Use this parameter if you want key position to affect panning. Positive (+) settings will cause notes higher than C4 key (center C) to be panned increasingly further toward the right, and negative (-) settings will cause notes higher than C4 key (center C) to be panned toward the left. Higher settings result in more change.

						+50	Chapter
o						0

L						-100	Key

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)

This setting causes panning to be alternated between left and right each time a key is pressed. Higher values will result in a greater width of change. This can be set either to L or R, which will invert the order in which the panning is moved between left and right. For example if two Tones are set to L and R respectively, the panning of the two Tones will alternate each time they are played.

When any value from Type 2–10 is selected for the Type parameter (PATCH/COMMON/STRUCT) in the Keyfollow, Random, Alternate parameter settings, the output of Tones 1 and 2 are joined in Tone 2, and the output of Tones 3 and 4 are joined in Tone 4. For this reason, Tone 1 will follow the settings of Tone 2, and Tone 3 will follow the settings of Tone 4 (p. 73).
