[linux-audio-user] usb thingy for controlling program changes

Hi

I'm looking for at USB thing that will store program changes, group them
in (a lot of) "patches" and then when selecting a "patch" will send the
stored program changes. A chain feature (that could be triggered by foot
switch) would also be nice. And most importent: it should work with
linux (the reason I ask here first).

Is such a thing out there?
