2. After selecting the desired bank, release the S1
switch, and you now will be able to select a patch
from the four patches in that bank, using each of
the four pedals.
<<fig. 2-6>>
3. When you wish to change groups, step on
[GROUP ↑] (pedal 2) while holding down [S1] as
in step 1.  Pedal 2 continues switching to the next
group only while [S1] is being held; pressing the
pedal allows you to progress to the next group.
<<fig. 2-7>>
4. After selecting the desired group/bank, let go of
the [S1] button as done in step 2, and you will now
be able to designate patches by stepping on the
pedals.

Using the Base Module plus
an External Footswitch to
Select Patches
By plugging a foot switch into the BANK SHIFT jack
on the rear panel, you can switch banks (the preced-
ing steps 1 and 2) without pressing [S1].
With one DP-5 (sold separately) to rise through patch
bank numbers, or with two Boss FS-5U foot switches
and a branch cable (sold separately) to move both up
and down through the patch banks, it’s possible to
perform this procedure using only your feet.
<<fig. 2-9>>
✽
Sometimes when pressing and releasing the foot switch
to switch banks, you may find that while the bank does
change, the patch number may not (light will flash);
however, this does not indicate any malfunction.  By
pressing first the [+] button then the [-] button, you can
return to the previous patch.  You can also make the set-
ting with the FS-5U polarity switch, as shown in the
figure below.
<<fig. 2-10>>
✽
If the PARAMETER SELECT dial has been set to
"PATCH INC/DEC BY S1/S2", the action of the foot
switch just described changes to switching patches up
and down (the same as PATCH [+] and [-] on the unit).
