Where to find wah on nanocortex

Hi,

New to all this so please excuse my mistakes, I have just purchased a used nanocortex. All seams ok but lots to go through before I use it, looks like it has firmware version 2.2.1 installed? Can anyone please tell me where to find the wah effect that I assume came with the firmware? Or am I missing something?

You can find wah in either of the 2 ‘pre’-effects slots under wah/filter.

Thank you will have a look
