Instrument Device - opening up the Instrument Device to load my own Fusion Patch was great, great feature for me. It allowed me to make the Looper by having different samples/loops for each note in the Fusion Sample. The only feature I would like to see is that the multiple Fusion Patches could be loaded to the Instrument (i.e. an array of fusion patches instead of just one in the settings). Then I could swap out sample packs.
