About the STEP RESET Function

04: Step Filter
18: Slicer
The above types contain a sixteen-step sequencer. For these types,
you can use an MFX CONTROL to reset the sequence to play from
the first step. To do this, set the MFX CONTROL Destination to
Reset."
For example, if you are using the modulation lever to control the
effect, you would make the following settings.
Parameter Value
CC01:
Source Modulation
Destination Step Reset
Sens +63
With these settings, the sequence will play back from the first step
whenever you operate the modulation lever.

Controlling an MFX via MIDI (MFX CONTROL)

You can use MIDI messages such as control change messages to
control the principal MFX parameters. This capability is called
CONTROL (multi-effects control)."
The parameters that can be controlled are preset for each MFX type,
and are the parameters marked by a
"Step
of each MFX parameter on p. 25 and following. Up to four multi-
effects control settings can be assigned using MFX CONTROL.
To use MFX CONTROL, you'll need to specify which MIDI message
(Source) will affect which parameter (Destination), and how greatly
(Sens).
Parameter
Source (1–4)
Destination

Sens (1–4)

Specifies the depth of MFX
CONTROL.
Specify a positive (+) value if you
want to change the value of the
assigned destination in a positive
direction (larger, toward the right,
-63–+63
faster, etc.), or specify a negative
(-) value if you want to change
the value in a negative direction
(smaller, toward the left, slower, etc.).
Larger values will allow a greater
amount of control.
