MFX PRM (MFX Parameter)
fig.07-09
MFX Parameter sets the parameters for the Multi-effects
selected by the Multi-effects type. For more detailed
information on the parameters that can be set in each Multi-
effect, please refer to “Multi-Effects Types” (p. 117).
When the Type parameter in the MFX TYPE page is set
to 00:THROUGH, the MFX PRM page will not be
displayed.
MFX CTRL (MFX Control)
fig.07-10
Use this when you want to change the Multi-effects
parameters in realtime using the specified MIDI messages.
• When the Type parameter in the MFX TYPE page is set
to 00:THROUGH, the MFX CTRL page will not be
displayed.
• In Performance mode, when the Source parameter in the
MFX TYPE page is set to PERFORM, you cannot use the
Multi-effects controller if the MFX Control Channel
parameter (PERFORM/COMMON/PERFORM MFX
CH) is set to OFF (p. 51).
What is the Multi-Effects Controller?
If you wanted to change the volume of Multi-effects
sounds, the delay time of Delay, and the like, 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 Multi-effects 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. For example, you can use the Pitch Bend lever to
change the amount of distortion, or use the keyboard’s
touch to change the delay time of Delay. The parameters
that can be changed are predetermined for each type of
multi-effect; among the parameters described in “Multi-
Effects Types” (p. 117), these are indicated by a #.
The function that allows you use MIDI messages to make
these changes in realtime to the Multi-effects parameters
is called the Multi-effects Controller. Up to four Multi-
effects Controllers can be used in a single Patch/Rhythm
Set/Performance.
When the Multi-effects Controller is used, you can select
the amount of control (Sens parameter) applied, the
parameter selected (Destination parameter), and the
MIDI message used (Source parameter).
By using the Matrix Controller instead of the Multi-
Effects controller, you can also change the
parameters of some popular Multi-effects in realtime
(p. 80).
