Attack
-64– +63 Adjusts the TVA/TVF Envelope Attack Time for the patch or rhythm set assigned to a part.
Releas -64– +63 Adjusts the TVA/TVF Envelope Release Time for the patch or rhythm set assigned to a part.
Decay -64– +63 Adjusts the TVA/TVF Envelope Decay Time for the patch or rhythm set assigned to a part.
Parameter
Value Explanation
Vib Rate
-64– +63 For each part, adjust the vibrato speed.
Depth -64– +63 For each part, this adjusts the depth of the vibrato effect.
Delay -64– +63 For each part, this adjusts the time delay until the vibrato.
Phase OFF, ON Set to “ON” when you want to suppress discrepancies in timing of parts played on the same MIDI channel.
* When this parameter is set to “ON,” parts on the same MIDI channel are put in a condition in which their timing is
matched, enabling them to be played at the same time. Accordingly, a certain amount of time may elapse between recep-
tion of the Note messages and playing of the sounds. Turn this setting to “ON” only as needed.
Parameter
Value Explanation
Kbd
OFF, ON (
) Specifies, for each part, whether or not the keyboard controller section will be connected to the internal sound
generator.
K.L C - –(Upper) Lowest note that the tone will sound for each part.
K.U (Lower)–G9 Highest note that the tone will sound for each part
When the Key Range (p. 42) is set for each individual tone in a patch, sounds are produced in the range where
the Key Range of each tone and the Key Range for the part overlap.
Velo -63– +63 Changes the volume and cutoff frequency for each part according to the velocity with which the keys are
pressed.
If you want strongly played notes to raise the volume/cutoff frequency, set this parameter to positive (+) set-
tings. If you want strongly played notes to lower the volume/cutoff frequency, use negative (-) settings. Set
Velocity Sensitivity to “0” when you want sounds played at a fixed volume and cutoff frequency, regardless
of the force with which the keys are played.
Curve OFF, 1–4 Selects for each MIDI channel one of the four following Velocity Curve types that best matches the touch of the
connected MIDI keyboard.
Set this to “OFF” if you are using the MIDI keyboard’s own velocity curve.
Voice 0–63, FUL This setting specifies the number of voices that will be reserved for each part when more than 128 voices are
played simultaneously.
* It is not possible for the settings of all parts to total an amount greater than 64. The remaining number of available voices
will be displayed at (rest=). Pay attention to this readout as you make Voice Reserve settings.

Calculating the Number of Voices Being Used
The Fantom-Xa is able to play up to 128 notes simultaneously. The
polyphony, or the number of voices (sounds) does not refer only
to the number of sounds actually being played, but changes
according to the number of tones used in the patches, and the
number of Waves used in the tones. The following method is used
to calculate the number of sounds used for one patch being
played.
(Number of Sounds Being Played) x (Number of Tones Used by
Patches Being Played) x (Number of Waves Used in the Tones)
Realtime Stretch requires twice the normal polyphony.
