Chapter 6. Creating a Rhythm Set
the Rhythm Tone’s stereo placement.
Alternate (Alternate pan depth) L64–63R 
This setting causes panning to be alternated between left and 
right each time a key is pressed. Higher values result in a 
greater left/right width. You can select the stereo placement 
of the first key using this parameter – its opposite will be 
used for the second note, and so on back and forth. If you 
want to alternate the pan position of two Rhythm Tones, set 
them to the exact opposite L and R settings.
TVA VELOCITY
Velocity Sens (TVA level velocity sensitivity) -
63–+63
Use this setting when you want keyboard touch (velocity) to 
affect the Rhythm Tone volume. Set this to a positive value to 
have the changes in tone volume increase the more forcefully 
the keys are played; to make the Rhythm Tone play more 
softly as you play harder, set this to a negative value.
Velocity Curve (TVA level velocity curve) 
FIXED/1–7
This setting allows you to select from seven velocity curves 
that determine how the force with which the keyboard is 
played is to affect the Rhythm Tone’s volume. The selected 
curve is displayed to the right of its parameter value.
When set to “FIXED,” the Rhythm Tone’s volume will not be 
affected by the force with which the keyboard is played.
TVA TIME ENV (TVA time envelope)
This specifies the manner in which keyboard velocity will 
affect the times of the TVA envelope.
V-T1 (TVA envelope time 1 velocity sensitivity)
Use this parameter when you want keyboard playing 
dynamics (velocity) to affect T1 (Time 1) of the TVA 
envelope. With higher settings, the T1 value will change 
more significantly depending on whether you play softly or 
with greater force. With positive (+) settings, greater 
keyboard velocity will reduce the T1 setting. With negative (-
) settings, greater keyboard velocity will increase the T1 
setting.
V-T4 (TVA envelope time 4 velocity sensitivity)
Use this parameter when you want key-off velocity – the 
speed at which you release a key – to affect T4 (Time 4) of the 
TVA envelope. With higher settings, the T4 value will change 
more significantly depending on whether you release the key 
slowly or quickly. With positive (+) settings, faster key-off 
velocity will reduce the T4 setting. With negative (-) settings, 
faster key-off velocity will increase the T4 setting.
TVA ENVELOPE
These parameters set the characteristics of the TVA envelope, 
which applies changes over time to the Rhythm Tone’s TVA 
level setting.
fig.6-1z.e
T1–T4 (TVA envelope time 1–4)
These settings determine the times over which the Rhythm 
Tone level setting will change from one TVA envelope level 
(L1–L4) to the next.
L1–L3 (TVA envelope level 1–3)
Each TVA envelope level value determines an amount of 
change to be applied to the original Rhythm Tone level 
setting.
Other Settings (CONTROL)
CONTROL
Bend Range (Tone pitch bend range) 0–48
Specifies the amount of pitch change that will occur when 
you move the Pitch Bend Lever. The left value specifies the 
pitch change that will occur when the lever is moved fully 
left (or down on some MIDI controllers). The right value 
specifies the pitch change that will occur when the lever is 
moved fully right (or up). The left value has a range of -48–0 
(-4–0 octaves), and the right value has a range of 0–+48 (0–4 
octaves).
Envelope Mode (Tone envelope mode) NO-
SUSTAIN/SUSTAIN
When a loop-type waveform is selected, it will normally 
continue to sound as long as a key is pressed. If you want a 
note to decay naturally even when the key remains pressed, 
set this to “NO-SUSTAIN.”
* If a one-shot type Wave is selected, it will not sustain even if 
this parameter is set to “SUSTAIN.”
Mute Group  OFF/1–31
The Mute Group function allows you to designate two or 
more Rhythm Tones that are not allowed to sound 
simultaneously. For example, in a real-world acoustic drum
