Amp

These TVA (Time Variant Amplifier) parameters specify how the volume and pan of the sound will change.

Parameter

Value

Description

 

 

 

 

 

Tone Level

0–127

Volume of each Rhythm Tone

 

(Rhythm Tone Level)

 

This parameter is used mainly to adjust the volume balance between Rhythm Tones.

 

Wave Level

0–127

Volume of each wave

 

 

 

This parameter is used mainly to adjust the volume balance between waves.

 

Tone Pan

L64–63R

Pan of each Rhythm Tone

 

(Rhythm Tone Pan)

 

L64 is far left, 0 is center, and 63R is far right.

 

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.

 

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

Mode

 

 

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.

Patch/Sample

(Wave Random Pan

L64–63R

or not (OFF).

Wave Pan

Pan of each wave

 

 

 

L64 is far left, 0 is center, and 63R is far right.

 

Wave Rnd Pan Sw

OFF, ON

Use this setting to cause the waveform’s panning to change randomly each time a key is pressed (ON)

 

Switch)

 

The range of the panning change is set by the Random Pan Depth setting.

 

Wave Alt Pan Sw

OFF, ON,

Set this to ON to pan the Wave according to the Alternate Pan Depth settings, or to REVS when you

 

(Wave Alternate Pan

REVS

want the panning reversed.

 

Switch)

 

If you do not want the panning to change each time a key is pressed, set this to OFF.

 

Amp Env (Amp Envelope)

These parameters specify the depth of the amp envelope (change in volume over time) and the shape of the envelope itself.

A-Env V-Curve

FIX, 1–7

Curve by which pad playing dynamics will affect the volume of the tone

(Amp Envelope

 

If you specify “FIX,” the volume of the tone will remain the same regardless of your playing dynamics.

A-Env V-Sens

-63– +63

Amount by which pad playing dynamics will affect the volume of the tone

(Amp Envelope

 

Specify a positive (+) value if you want the volume of the tone to increase as you play more strongly.

Velocity Sensitivity)

 

Specify a negative (-) value if you want the volume to decrease.

A-Env T1 V-Sens

-63– +63

Amount by which T1 (time) of the Amp envelope will change in response to your playing dynamics

(Amp Envelope

 

Increasing this value will produce a greater change between softly played and strongly played notes.

Time 1 Velocity

 

Specify a positive (+) value if you want the T1 time to speed up, or a negative (-) value if you want it

Sensitivity)

 

to slow down.

 

 

 

 

 

A-Env T4 V-Sens

-63– +63

Amount by which T4 (time) of the Amp envelope will change in response to the speed at which you

(Amp Envelope

 

release the pad (key-off velocity)

 

 

 

 

Time 4 Velocity

 

Increasing this value will produce a greater change between slowly released and quickly released

Sensitivity)

 

notes. Specify a positive (+) value if you want the T4 time to speed up, or a negative (-) value if you

 

 

want it to slow down.

 

 

 

 

 

A-Env Time1–4

0–127

Amp envelope times (T1–T4)

 

 

 

 

(Amp Envelope

 

Higher settings of these values will lengthen the time over which the next volume level of the enve-

Time 1–4)

 

lope is reached. (For example, T2 is the time over which the level changes from L1 to L2.)

 

 

* Realtime modify knob [A] adjusts Time 1, knob [D] adjusts Time 3, and knob [R] adjusts Time 4.

A-Env Level1–3

0–127

Amp envelope levels (L1–L3)

 

 

 

 

(Amp Envelope

 

Specifies the change in volume at each point, relative to the reference level.

Level 1–3)

 

* Realtime modify knob [S] adjusts Level 3.
