Chapter 9. Getting More Familiar with the XV-88 (System Functions)

Beat Pattern

Select the beat pattern from the choices below. This setting will affect the location of the accent and length of the notes to determine the beat (rhythm).

Some settings will not be available depending on the Style parameter setting. For details on the possible values, refer to “Arpeggio Style List” (p. 268).

1/4, 1/6, 1/8, 1/12, 1/16 1–3, 1/32 1–3, PORTA-A 01–11, PORTA-B 01–15, SEQ-A 1–7, SEQ-B 1–5, SEQ-C 1, 2, SEQ-D 1–8, ECHO 1–3, MUTE 01–16, STRUM 1–8, REGGAE 1, 2, REFRAIN 1, 2, PERC 1–4, WALKBS, HARP,

BOUND, RANDOM, BOSSA NOVA, SALSA 1–4, MAMBO 1–2, CLAVE, REV CLA, GUILO, AGOGO, SAMBA, TANGO 1–4, HOUSE 1, 2

If “PORTA-A 01–11, PORTA-B 01–15” is selected as the Beat Pattern, the Time parameter (PATCH/CONTROL/ PATCH PORTAMNT) will control the speed of portamento (p. 76). Adjust the portamento time as appropriate for the playback tempo. (It is not necessary to turn portamento switch on.)

Accent Rate

Modifies the strength of accents and the length of the notes to adjust the “groove” feel of the arpeggio. A 100% setting will result in the most pronounced “groove” feel.

Shuffle Rate

This setting lets you modify the note timing to create shuffle rhythms.

With a setting of 50%, the notes will sound at equal spacing. As this value is increased, the notes will become more “bouncy,” as if they were dotted notes.

Shuffle Rate = 50%				Shuffle Rate = 90%
50	50	50	50	90	10	90	10

If the Beat Pattern setting is 1/4, shuffle will not be applied even if you increase the Shuffle Rate setting.

Key Velocity

Specifies the loudness of the notes that you play.

If you want the velocity value to change according to how strongly you played each note, set this to REAL. If you want each note to have a fixed velocity regardless of how strongly you play the keyboard, set this parameter to the desired value (1–127).

Tempo (Arpeggio Tempo)

Sets the speed of the arpeggio.

When the Clock Source parameter (SYSTEM/SETUP/ SYSTEM SETUP) is set to INT, the display will indicate Tempo(=SYS), and this will be the same value as the system tempo. With a setting of MIDI, the display will indicate Tempo(=EXT), and you will be synchronized to the clock of the external MIDI device.

Setting the D Beam Controller (D BEAM)

This is where the settings are made for applying effects to the sound by moving your hand over the D Beam controller in Patch/Rhythm Set/GM mode.

When using the D Beam controller in Performance mode, the settings are made in Zone mode (p. 63).

D BEAM CONTROL

Assign (D Beam Assign)

Specifies the function controlled by the D Beam controller. CC01–31,33–95: Controller numbers 1–31, 33–95

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

PITCH BEND: Pitch Bend

AFTERTOUCH: Aftertouch

OCT UP: Raises the key range in octave steps (up to 3 octaves

higher).

OCT DOWN: Lowers the key range in octave steps (up to 3 octaves lower).

START/STOP: Starts/Stops the external sequencer.

TAP TEMPO: Tap tempo (a tempo specified by the interval at which you move your hand over the D Beam controller).

Output (D Beam Output)

Selects the sound generator(s) (the internal sound generator and/or external sound generators connected to MIDI OUT connector) to be controlled by the D Beam controller.

OFF: Neither will be controlled.

INT: Only the internal sound generator will be controlled.

MIDI: Only external sound generators will be controlled.

BOTH: Both the internal sound generator and external sound generators will be controlled.
