■Using the AFR Function
After you have switched ON (activated) the AFR function us-
ing the procedure described on the previous page, the “«”
edit icon will appear for patches that can use the AFR func-
tion (patches that have their effect type set to “AcousticMulti”).
*The normal “¤” edit icon appears when the AFR function is set OFF (inactive), or when a patch is selected that
uses an effect type other than “AcousticMulti”.
After selecting a patch in which the AFR function is active, follow the instructions below to use the
AFR function.
*The AFR function’s switch operation differs in the Up/Down Mode and Performance Mode.
qWhen feedback occurs in the Up/Down Mode press the ON/OFF switch, and
when in the Performance Mode press the switch that corresponds to the cur-
rently selected patch (–, ON/OFF, +).
*The switches in the procedure described above (–, ON/OFF, +) can not be used to switch effects ON/OFF in
patches that have the AFR function active.
The MAGICSTOMP will automatically identify the frequency causing the feedback and activate
an unused notch filter. When the filter identifies the problem frequency, the display will appear
similar to that shown below and then return to its previous condition.
To indicate that the AFR function is active, the ON/OFF switch’s lamp will flash when in the Up/
Down Mode, while in the Performance mode, the switch’s lamp (–, ON/OFF, +) for the currently
selected patch will flash.
*If the filter fails to be set, the following display is shown before return-
ing to its previous condition.
wIf the application of a single band filter does not take care of the feedback, press
the switch as described in step q and set a second filter. A maximum of 5 band
filters can be set.
*The following display will appear if all 5 filters have been set.
The AFR Function’s settings are not saved along with patch data. And the AFR
Function’s settings are cancelled when another patch is selected.
