Chapter 5. Creating Patches

Rel (Release Time Offset)

Release Time Offset alters the release time of the overall Patch, while preserving the relative differences between the release time values set for each Tone in the T4 parameters (PATCH/TVA/TVA ENVELOPE) (p. 92).

*Release Time: The time from when you take your finger off the key until the sound disappears

Since the values for the T4 parameters for each Tone are added to the values made in this setting, if the T4 parameters are set to 127 (maximum), then no further changes are made, even when a positive value is used for this setting.

Velocity Sens (Velocity Sensitivity Offset)

Velocity Sensitivity Offset alters the Velocity Sensitivity of the overall Patch while preserving the relative differences between the Velocity Sensitivity values set for each Tone in the parameters below.

V-Cutoff parameter (PATCH/TVF/TVF VELOCITY) (p. 89)

V-Sens parameter (PATCH/TVA/TVA) (p. 90)

* Velocity: Pressure with which the key is pressed

Since this settings value is added to the V-Cutoff and V- Sens parameter values for each Tone, if the V-Cutoff and V-Sens parameter values are set to +63 (maximum), then no further changes are made, even when a positive value is used for this setting.

TMT VELO CONTROL (TMT Velocity Control)

You can have the XV-88’s keyboard produce different tones according to the register, the force with which the keys are played, or a variety of different MIDI messages. The group of settings affecting this is called the TMT (Tone Mix Table).

TMT Velocity Control

(TMT Velocity Control Switch)

TMT Velocity Control determines whether a different Tone is played (ON) or not (OFF) depending on the force with which the key is played (velocity).

When set to RANDOM, the Patch’s constituent Tones will sound randomly, regardless of any Velocity messages.

Instead of using Velocity, you can also have Tones substituted using the Matrix Controller (p. 80). However, the keyboard velocity and the Matrix Controller cannot be used simultaneously to switch Tones. When using the Matrix Controller to switch Tones, set the TMT Velocity Control to OFF.

TMT VEL RANG (TMT Velocity Range)

Specifies the range of playing dynamics (key velocity) which will sound the Tone. Make these settings when you want different Tones to sound in response to notes played at different strengths.

When the TMT Velocity Control parameter (PATCH/ COMMON/TMT VELO CONTROL) is set to OFF, you cannot change the tone that is played according to the force with which the keys are played (velocity).

When using the Matrix Controller to have different Tones played, set the range within which the Tone is to be sounded according to the value of the MIDI message used.

Lower (Velocity Range Lower)

Upper (Velocity Range Upper)

For each Tone, specify the lower (Lower) and upper (Upper) limit of the key velocities that will sound the Tone. When a key is played more softly than the lower limit, or more strongly than the upper limit, the sound will either not be heard at all or will be extremely weak.

If you attempt to set the Lower velocity limit above the Upper, or the Upper below the Lower, the other value will automatically be adjusted to the same setting.

When using the Matrix Controller to have different Tones played, set the lowest value (Lower) and highest value (Upper) of the value of the MIDI message used.
