CHO PRM (CHO Parameter)
fig.07-14
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.
