Value Description
0–127 This sets the Rhythm Tone's basic volume. This setting is useful primarily for adjusting the volume balance between
Rhythm Tones in a Rhythm Set.
* The overall volume of the Rhythm Set is set by the Level (Rhythm Set Level, COMMON group p. 55) setting, rais-
ing or lowering the Tone level settings of its individual Rhythm Tones by the selected amount.
L64–63R This specifies the stereo position of the Rhythm Tone. L64 places the Rhythm Tone hard left, 0 puts it dead-center
and 63R pans it hard right.
0–63 Use this parameter to activate random panning, note-by-note. Higher values result in more extreme fluctuations in
the Rhythm Tone's stereo placement.
L63–63R 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.
-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.
FIXED, This setting allows you to select from seven velocity curves that determine how the force with which the keyboard
1–7 is played is to affect the Rhythm Tone's volume. When set to "FIXED," the Rhythm Tone's volume will not be affect-
ed by the force with which the keyboard is played.

-63– +63 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 (-) set-
tings, greater keyboard velocity will increase the T1 setting.
-63– +63 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 re-
lease the key slowly or quickly. With positive (+) settings, faster key-off velocity will reduce the T4 setting. With neg-
ative (-) settings, faster key-off velocity will increase the T4 setting.
0–127 Specify the TVA envelope times. Higher settings lengthen the time until the next volume level is reached. (For ex-
ample, T2 is the time over which L1 changes to L2.)
0–127 Specify the TVA envelope levels. These settings specify how the volume changes at each point, relative to the stan-
dard volume.
Value Description
0–48 Specifies the amount of pitch change that will occur when you move the Pitch Bend Lever.
NO-SUS, 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."
SUSTAIN
* If a one-shot type Wave is selected, it will not sustain even if this parameter is set to "SUSTAIN."
OFF, 1–31 The Mute Group function allows you to designate two or more Rhythm Tones that are not allowed to sound simulta-
neously. For example, in a real-world acoustic drum set, an open hi-hat and a closed hi-hat sound will never occur si-
multaneously, since they're produced by the same instrument. To simulate this behavior on the XV-5050, you can set
the open and closed hi-hat Rhythm Tones to the same Mute Group. You can have up to 31 Mute Groups per Rhythm
Set. If you do not want a Rhythm Tone to use a Mute Group, turn the feature off.
MULTI,
This setting determines whether a Rhythm Tone note that is playing is stopped when the same note is played again
SINGLE (SINGLE), or whether it will continue to play, layered with the new note.
OFF, ON If you want the Rhythm Tone to respond to Expression messages, turn this parameter on. If not, turn it off.
CONT, CONT: Pan messages will be responded to immediately, instantly changing the stereo position of the Rhythm Tone.
KEY-ON: The stereo location of the Rhythm Tone will be changed only when the next note is played. If a Pan message
KEY-ON
is received while a note is sounding, its stereo location will not change.
OFF, ON If you want the Tone to respond to Hold 1 messages, turn this parameter on. If not, turn it off.
