Boss VF-1 Effect Processor

Hi,

i'm thinking of buying a Behringer FCB1010 Midi Foot controller.
What is the quality of the Wah?
Is the VF-1 fast enough to handle midi datas for fast Wah playing?
Is a analog expression pedal like the BOSS EV-5 better for handling
the Wah effekt?

Does anybody has experiences with both methods? Speed is important

Greetings Faro.

Btw. Is there any possibility to change the algorithm of a patch? Or
do i have to start a new patch from an preset with this different
algo?. The manuals says thats not possible, though it is with the help
of the sounddiver editor
