Rhythm Edit
Patch/Sample Mode
Amp
These TVA (Time Variant Amplifier) parameters specify how the volume and pan of the sound will change.
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.
Parameter Value Description
Tone Level
(Rhythm Tone Level) 0–127 Volume of each Rhythm Tone
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
(Rhythm Tone Pan) L64–63R Pan of each Rhythm Tone
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
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.
Wave Pan L64–63R Pan of each wave
L64 is far left, 0 is center, and 63R is far right.
Wave Rnd Pan Sw
(Wave Random Pan
Switch) OFF, ON Use this setting to cause the waveform’s panning to change randomly each time a key is pressed (ON)
or not (OFF).
The range of the panning change is set by the Random Pan Depth setting.
Wave Alt Pan Sw
(Wave Alternate Pan
Switch) OFF, ON,
REVS Set this to ON to pan the Wave according to the Alternate Pan Depth settings, or to REVS when you
want the panning reversed.
If you do not want the panning to change each time a key is pressed, set this to OFF.
Parameter Value Description
A-Env V-Curve
(Amp Envelope
Velocity Curve) FIX, 1–7 Curve by which pad playing dynamics will affect the volume of the tone
If you specify “FIX,” the volume of the tone will remain the same regardless of your playing dynamics.
A-Env V-Sens
(Amp Envelope
Velocity Sensitivity) -63– +63 Amount by which pad playing dynamics will affect the volume of the tone
Specify a positive (+) value if you want the volume of the tone to increase as you play more strongly.
Specify a negative (-) value if you want the volume to decrease.
A-Env T1 V-Sens
(Amp Envelope
Time 1 Velocity
Sensitivity) -63– +63 Amount by which T1 (time) of the Amp envelope will change in response to your playing dynamics
Increasing this value will produce a greater change between softly played and strongly played notes.
Specify a positive (+) value if you want the T1 time to speed up, or a negative (-) value if you want it
to slow down.
A-Env T4 V-Sens
(Amp Envelope
Time 4 Velocity
Sensitivity) -63– +63 Amount by which T4 (time) of the Amp envelope will change in response to the speed at which you
release the pad (key-off velocity)
Increasing this value will produce a greater change between slowly released and quickly released
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
(Amp Envelope
Time 1–4) 0–127 Amp envelope times (T1–T4)
Higher settings of these values will lengthen the time over which the next volume level of the enve-
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
(Amp Envelope
Level 1–3) 0–127 Amp envelope levels (L1–L3)
Specifies the change in volume at each point, relative to the reference level.
* Realtime modify knob [S] adjusts Level 3.
