Roland XV-88 owner manual CHO PRM CHO Parameter, 157

CHO PRM (CHO Parameter)

Sets the parameter for the Chorus selected by the Chorus type. The parameters that can be set differ according to whether chorus or delay is used.

When the Type parameter in the CHO TYPE page is set to 00:OFF, the CHO PRM page will not be displayed.

●For Type: CHORUS

Pre Dly (Chorus Pre Delay)

This specifies the delay between when the direct sound is heard and when chorusing begins.

Rate (Chorus Rate)

This specifies the modulation frequency of the chorus effect.

Depth (Chorus Depth)

This specifies the modulation depth of the chorus effect.

Fbk (Chorus Feedback)

This specifies the amount of the chorus effect’s output to be returned - fed back - to its input. Higher settings create more complex chorusing.

Phase

This specifies the spaciousness of the chorus effect.

Filter Type

This specifies the type of filter to be used by the chorus effect. OFF: No filter is used.

LPF: Frequencies higher than the selected cutoff frequency value are eliminated.

HPF: Frequencies lower than the selected cutoff frequency value are eliminated.

Cutoff (Cutoff Frequency)

This sets the cutoff frequency at which the LPF or HPF begin to work.

Chapter 7. Adding Effects

●For Type: DELAY

Delay C (Delay Center)

This sets the delay time for the delay located at the center of the stereo field.

Delay L (Delay Left)

This sets the delay time for the delay located at the left side of the stereo field.

Delay R (Delay Right)

This sets the delay time for the delay located at the right side of the stereo field.

Delay C, Delay L and Delay R parameters can be set as a note-value of a specified tempo. In this case, specify the value of the desired note.

When Delay C, Delay L and Delay R are Set as a Note Value

As the specified tempo, you may use either the Patch Tempo (p. 71) or the tempo clock of the XV-88’s system (p. 169).

Fbk (Feedback)

This adjusts the amount of delay feedback, controlling the number of times the delay repeats. Higher values result in more repeats. With negative (-) values, the phase of the repeated delays is inverted.

Level C (Delay Center Level)

This sets the volume level of the delay located at the center of the stereo field.

Level L (Delay Left Level)

This sets the volume level of the delay located at the left side of the stereo field.

Level R (Delay Right Level)

This sets the volume level of the delay located at the right side of the stereo field.

HF Damp

This allows you to reduce, or “damp,” the high-frequency content of the repeated feedback delays—frequencies above the selected value will be damped. If you do not wish to damp the high-frequency content of the feedback delays, set this parameter to BYPASS.
