Hello and thank you for your message,

i didn't know the MIDI learn function , but i have still a problem :

when i take for exemple the pedale " Vettah Wah " i insert it in my preset , i assign a MIDI learn with the button switch and another with the move of the pedale to have the Wah effect. It works good .

But when i disable the vettah wah in my preset it sounds still different

i mean when the "vettah wah" is present , the sound is different event if the vettah wah is disable!  it's feels like the tone has been changed only by the presence of the vettah wah.

I tried to use the wah of the "chrome custom" like in the video but podfarm tell me it can't be used with the connected device ( my device is a fbv express mkii )

thank you in advance i hope you have understood my english
