Anyone knowns of an input device (some specialized USB joystick maybe ...) that could be use as a multiple effect switch for a linux PC ? I don't know if this exist yet, but I can certainly see software support in "jack-rack" for instance to enable/disable effect.. a footswitch made of a winmang "Rumble Pad" for instance could also be use to control the selected slider ... Would that be of use to anyone ? Frank
