Chapter 3. Creating Performances

Calculating the Number of Voices Being Used

The XV-88 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)

MODIFY

Cut (Part Cutoff Frequency Offset)

Adjusts the cutoff frequency for the Patch or Rhythm Set assigned to a Part.

Patches also have a Cutoff Frequency Offset setting (p. 71). The final Cutoff frequency value is the sum of the Tone Cutoff Frequency value and the Patch and Part Cutoff Frequency Offset values. If the Tone’s cutoff frequency is already set to 127 (maximum), there will be no change produced by setting the Cutoff Frequency Offset to a positive value.

Res (Part Resonance Offset)

Adjusts the Resonance for the Patch or Rhythm Set assigned to a Part.

Patches also have a Resonance Offset setting (p. 71). The final Resonance value is the sum of the Tone Resonance value and the Patch and Part Resonance Offset values. If the Tone’s resonance is already set to 127 (maximum), there will be no change produced by setting the resonance offset to a positive value.

Atk (Part Attack Time Offset)

Adjusts the TVA Envelope Attack Time for the Patch or Rhythm Set assigned to a Part.

Patches also contain the Attack Time Offset setting (p. 71). The final TVA Envelope attack time value is therefore the sum of the Tone’s TVA Envelope T1 setting, the Patch’s Attack Time Offset, and the Part’s Attack Time Offset. If the Tone’s T1 parameter is already set to 127 (maximum), there will be no change produced by setting the Attack Time Offset to a positive value.

Rel (Part Release Time Offset)

Adjusts the TVA Envelope Release Time for the Patch or Rhythm Set assigned to a Part.

Patches also contain a Release Time Offset setting (p. 72). The final TVA Envelope release time value is therefore the sum of the Tone’s TVA Envelope T4 setting, the Patch’s Release Time Offset, and the Part’s Release Time Offset. If the tone’s T4 parameter is set to 127 (maximum), there will be no change in the Release Time Offset, even when this is set to a positive value.

Velocity Sens (Part velocity Sensitivity Offset)

This 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 (+) settings. 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.

Patches also contain a Velocity Sensitivity Offset setting (p. 72). The ultimate Velocity Sensitivity Offset value is the sum of the part’s and the Patch’s Velocity Sensitivity Offsets. Accordingly, if the Patch’s Velocity Sensitivity Offset T1 parameter is set to 127 (maximum), there will be no change in the part’s Velocity Sensitivity Offset, even when this is set to a positive value.

PITCH

Octave (Part Octave Shift)

Adjusts the pitch of the Part’s sound up or down in units of

an octave (+/-3 octaves).
