Using Midi To Control The Multi-Effects (Mfx1-3 Control Screens) - Roland SonicCell User Manual

Using MIDI to control the multi-effects (MFX1–3 Control screens)
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 SonicCell. 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 SonicCell'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 Parameter (MFX1–
3, MFX)" (p. 192), 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 Control.
You can specify up to four controls for each multi-effect MFX 1–3.
When the multi-effects control is used, you can select the amount of control (Sens) applied, the parameter selected (Dest), and the
MIDI message used (Src).
By using the Matrix Control (p. 95) instead of the Multi-effects Control, you can also change the parameters of some popular multi-
effects in realtime.

ter" (p. 192)
Sets the amount of the multi-effects control's effect that is applied.
If you wish to modify the selected parameter in a positive (+) direction—i.e., a high-
er value, toward the right, or faster, etc.—from its current setting, select a positive
-63–+63
(+) value. If you wish to modify the selected parameter in a negative (-) direction–
i.e., a lower value, toward the left, or slower, etc.—from its current setting, select a
negative (-) value. Higher numbers produce a greater amount of change.
This determines the channel that will be used for reception when using the Multi-
1–16, OFF effects Control to modify multi-effects parameters in real time, when the MFX1–3 Src
is set to "PFM." Set this to "OFF" when the Multi-effects Control is not being used.
Using the SonicCell in Performance Mode
Multi-effects control will not be used.
