Turn off the CTL PEDAL control assign (just too
be sure)

Now exit back to the main play display
Press the UTILITY button 3 times to get the
'SYSTEM' parameters up.
Check the [GT-3] SUB CTL 1 and SUB CTL 2 or
[GT-5] EXP/CTL 1 or 2 parameters are set to
ASSIGNABLE as appropriate. On the GT-3 if
either are set to manual or tuner on/off the EV5
ceases to work. The same is true on the GT-5 if the
EXP/CTL jack in question is set to manual or tuner
on/off.
Exit back to the main play display
Press the MASTER button and step through the
parameters until you get to the FV: Level
parameter.
Set the minimum volume control on the external
expression pedal (Such as on the EV5) to 0. This is
very important.
Move the expression pedal.
Et Viola! You should be able to see the FV:Level
changing in the display.
This example teaches us that the most important settings
when setting up the external expression pedal are the global
[GT-5]EXP/CTL 1/2 or [GT-3]SUB CTL 1/2 parameters
are set to 'Assignable', and to avoid conflicting
assignments.
Neither the GT-3 nor the GT-5 provides facilities to
calibrate external expression pedals. Thus, the only problem
with the Roland EV5 is that it suffers from LARGE dead
spots at the top and bottom of the pedal travel making it
unsuitable for use a WAH controller. This can be avoided
by using the on-board pedal for WAH and the external as a
foot volume (which is less sensitive in terms of use, to any
dead spots which exist – unless you are using foot
controlled tremolo) but ensure you are consistent as
swapping pedal usage between patches is only likely to
cause confusion.
The external expression pedals should work as well as the
on-board expression pedal, although there are a couple of
configuration parameters to be aware of though.
In the <Global> settings you can allocate each
pedal as being either a Foot Volume or assignable. It
obviously makes no sense to set both external expression
pedals to control FV. If you specify them as assignable, they
may be freely used in a patch's control assigns. However, if

you assign them the FV functionality, then this is a
GLOBAL assignment and OVERRIDES any control
assigns, regardless whether or not the control assign in
question is on or off.
To use the external expression pedals, you must use one of
the eight Control assigns. When configuring these, set the
Internal 'Source' to [GT-3] SUB EXP or [GT-5]
EXP/CTL1 or EXP/CTL2. If you are configuring the
control assign to set off the Internal Pedal, set the 'Trigger'
to [GT-3] SUB EXP L, M or H or [GT-5] EXP/CTL1 L, M
or H or EXP/CTL 2 L, M or H.
If you find yourself without enough expression pedals (!)
then I recommend you use MIDI based ones that output CC
messages. The GT-3/5 control assigns can all be triggered
by MIDI instead of the on-board/external pedals.
