Description
Volume of each Rhythm Tone
This parameter is used mainly to adjust the volume balance between Rhythm Tones.
Volume of each wave
This parameter is used mainly to adjust the volume balance between waves.
Pan of each Rhythm Tone
L64 is far left, 0 is center, and 63R is far right.
Amount by which the pan will be varied randomly each time you press a pad
Increasing this value will produce a greater amount of random change.
Amount by which the pan will be moved alternately between left and right each time you press a pad
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.
Pan of each wave
L64 is far left, 0 is center, and 63R is far right.
Use this setting to cause the waveform's panning to change randomly each time a pad is pressed (ON)
or not (OFF).
The range of the panning change is set by the Random Pan Depth setting.
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 pad is pressed, set this to OFF.

Description
Curve by which velocity will affect the volume of the tone
If this is "FIX," the volume of the tone will stay the same regardless of how the velocity varies.
1 2
Amount by which velocity will affect the volume of the tone
Set a positive (+) value if you want to increase the tone's volume change, or a negative (-) value if you
want to decrease the tone's volume change.
Amount by which velocity will affect T1 (time) of the Amp envelope
Specify a positive (+) value if you want the T1 time to speed up, or a negative (-) value if you want it
to slow down.
Amount by which T4 (time) of the Amp envelope will change in response to the key-off velocity
Specify a positive (+) value if you want the T4 time to speed up, or a negative (-) value if you want it
to slow down.
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.)
Amp envelope levels (L1–L3)
Specifies the change in volume at each point, relative to the reference level.
