Specifying The Multi-Effects Structure (Mfx Structure) - Roland Fantom-Xa Owner's Manual

multi-effects control, confirm that any MIDI messages used for the multi-effects control will be received. If the Fantom-Xa is set up such that
reception of MIDI messages is disabled, then the multi-effects control will not function.
Multi-Effects Control
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 Fantom-Xa. 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 Fantom-
Xa'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 Parameters (p. 164), these are indicated by a "#."

Specifying the Multi-Effects Structure (MFX Structure)

Here's how to specify how MFX 1–3 will be connected.
* This parameter is not found in Patch mode.

For details on these settings, refer to Making Effect Settings (p. 157).
Parameter Value
Struct TYPE01–TYPE16
(MFX1–3 Type) 00 (THRU)–78
Explanation
Specifies how MFX1–3 will be connected.
Selects the multi-effect type of MFX1–3.
In the multi-effect setting screen, a "c" symbol will be shown at
the left of the parameter.
The function that allows you use MIDI messages to make these
changes in realtime to the multi-effects parameters is called the
Multi-effects Control. Up to four multi-effects controls can be
used in a single patch/rhythm set/performance.
When the multi-effects control 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 Control instead of the Multi-effects
Control, you can also change the some popular parameters
of multi-effects in realtime (p. 49).
