DORE MIDI FC 3 Foot Switching with AUM

Setting up simple foot switch in in AUM. The DOREMIDI FC3 is recognized as a USB MIDI device. Ive connected the footswitch and my Yamaha WX7 using a powered USB hub and a DOREMIDI USB interface. First couple minutes show the connections and mapping and a little after 2:00 the sound begins when I start demoing and playing.
