Hi Rafail, and congratulations on owning one of the coolest devices in digital audio history. : )  (I say this purlely as a satisfied owner -- I have no affiliation with Line 6. In fact, they used to drive me nuts, but their support staff has *really* stepped it up in the last 6-12 months.)

To answer your question (unofficially), I believe the answer is No. Pod farm doesn't yet recognize the footswitches or expression pedal on the KB37. That is one major reason why I keep GearBox installed on my computer.

Here's a tip if you want an official answer from Line 6:  When you post a question that you want addressed by a Line 6 staffer, don't forget to check the box labeled "Mark this as a question".

Here are some more tips on getting good support from Line 6:

And if all else fails, contact their main support number. (I recommend you do this only when you've exhausted all of the options in that Support FAQ.)

I speak openly, as a formerly very dissatisfied Line 6 customer: They have MAJORLY improved their support, which was sorely needed. The support forums are still hard to navigate and understand, but the link I gave you above should help you get the most out of the company's "new" support, which has redeemed me as a satisfied customer.

If all else fails, feel free to private-message me. Let me know if the Line 6 support staff is living up to your expectations. I can't stress enough how much they've gone from "unacceptable" to "awesome" in the last year or two. Nobody's perfect, but it's great to see the company putting in a solid and rewarding effort.

Cheers,
