Chapter 5. Creating Patches

Redamper (Redamper Switch)

When a Hold 1 message is received after a key was released but before the sound has completely decayed, this setting specifies whether or not the sound will be sustained at that level. If you want to sustain the sound, set this ON. When using this function, also set the Hold-1 parameter ON. This function is effective for piano sounds.

Envelope Mode

When a loop-type waveform (p. 68) 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 (p. 68) is selected, it will not sustain even if this parameter is set to SUSTAIN.

TMT CTRL&BENDER (TMT Control & Bender)

TMT Ctrl Sw (TMT Control Switch)

Use the Matrix Controller to enable (ON), or disable (OFF) sounding of different tones.

You can also cause different tones to sound in response to notes played at different strengths (velocity) on the keyboard. However, the Matrix Controller and the keyboard velocity cannot be used simultaneously to make different Tones to sound. When you want to make the different Tones to sound, set the TMT Velocity Control parameter (PATCH/COMMON/TMT VELO CONTROL) to OFF.

Bend Range

Specifies the amount of pitch change (in semitones) that will occur when the Pitch Bend Lever is moved (-4– +4 octaves). The left value specifies the pitch change that will occur when the lever is moved fully left. The right value specifies the pitch change that will occur when the lever is moved fully right. For example, if the right value is set to 12, the pitch will rise one octave when the bender lever is moved to the right- most position.

What is the Matrix Controller?

Ordinarily, if you wanted to change Tone parameters using an external MIDI device, you would need to send System Exclusive messages—MIDI messages designed exclusively for the XV-88. However, System Exclusive messages tend to be complicated, and the amount of data that needs to be transmitted can get quite large.

For that reason, a number of the more typical of the XV- 88’s Tone parameters have been designed so they accept the use of Control Change (or other) MIDI messages for the purpose of making changes in their values. This provides you with a variety of means of changing the way Patches are played. For example, you can use the Pitch Bend lever to change the LFO cycle rate, or use the keyboard’s touch to open and close a filter.

The function which allows you use MIDI messages to make these changes in realtime to the Tone parameters is called the Matrix Controller. Up to four Matrix Controllers can be used in a single Patch.

When the Matrix Controller is used, you can select the amount of control (Sns parameter) applied, the parameter selected (Dest parameter), the MIDI message used to transmit the effect (Control 1–4 parameter), and the Tone to which the effect is applied (Tone parameter).

Control 1–4 (Matrix Control Source 1–4)

Sets the MIDI message used to change the Tone parameter with the Matrix Controller. Set this to OFF when the Matrix Controller is not being used.

The following are MIDI messages that can be used as Matrix Controllers.

•Controller Numbers 01–31, 33–95 (CC01–CC31, CC33– CC95)

For more information about Control Change messages, please refer to “MIDI Implementation” (p. 270).

•Pitch Bend (PITCH BEND)

•Aftertouch (AFTERTOUCH)

•System Controller 1–4 (SYS-CTRL1–SYS-CTRL4): MIDI messages used as global Matrix Controllers
