Parameter	Value	Description
ENV TIME KF	-100–+100	Use this parameter when you want the keyboard location of
(Pitch Envelope Time Key-		notes to affect times T2–T4 of the pitch envelope. Higher val-
follow)		ues for this parameter cause more extreme changes to the T2–
		T4 settings as you play further away from Middle C (C4)—at
		Middle C itself, your original T2–T4 settings are in effect. Pos-
		itive (+) settings cause the times to be shortened for notes
		above Middle C. Negative (-) settings cause the times to be
		lengthened for notes above Middle C.

ENV VEL SENS	-63–+63	Adjust this parameter when you want your keyboard playing

Sensitivity)		With higher settings, there is a greater difference in the
		amount of enveloping when notes are played softly or when
		they’re played hard. Negative (-) settings reverse the direction
		of change.
ENV T1 SENS	-63–+63	Use this parameter when you want keyboard playing dynam-
(Pitch Envelope Time 1		ics to affect T1 (Time 1) of the pitch envelope. If you want T1
Velocity Sensitivity)		to be sped up for strongly played notes, set this parameter to a
		positive (+) value. If you want it to be slowed down, set this to
		a negative (-) value.
ENV T4 SENS	-63–+63	Use this parameter when you want key release speed to affect
(Pitch Envelope Time 4		T4 (Time 4) of the pitch envelope. If you want T4 to be sped up
Velocity Sensitivity)		for quickly released notes, set this parameter to a positive (+)
		value. If you want it to be slowed down, set this to a negative
		(-) value.
ENV T1–T4	0–127	Specify the pitch envelope times. Higher settings lengthen the
(Pitch Envelope Time1–4)		time until the next pitch is reached. (For example, T2 is the
		time over which the pitch changes from L1 to L2.)
ENV L0–L4	-63–+63	Specify the pitch envelope levels. They determine how much
(Pitch Envelope Level 0–4)		the pitch changes from the reference pitch (the value set with
		Coarse Tune and Fine Tune) at each point. Positive (+) settings
		cause the pitch to be higher than the standard pitch, and neg-
		ative (-) settings cause it to be lower.

PATCH LFO (Applying Vibrato or Tremolo)

The LFO (Low Frequency Oscillator) can alter various Tone settings in a back-and-forth, cyclic manner. Each Tone has two LFOs, and each can apply the desired amount of repetitive change to the Tone’s Pitch, TVF cutoff frequency, TVA Level and TVA Pan settings. This can be used as the Matrix Control source (p. 50).

How to Use the LFO

Applying an LFO to the Tone’s Pitch settings creates vibrato, applying it to its TVF cutoff frequency creates a wah-wah, and applying it to its TVA Level creates tremolo. When an LFO is applied to the Tone’s TVA Pan, the sound moves back and forth, from one side to another, in the stereo field.

Depending on your settings, an LFO can also be used to cyclically exchange two Tones. For example, if you wish to shift back and forth between Tones 1 and 2, select the same LFO settings for both, but set their LFO TVA Depth settings to opposite polarities—set one to a + value, and the other to a - value.

*LFO Since both LFOs have the same parameters, the following explanations apply to both.
