Duboule

Hey all ! I'm currently the happy owner of a Helix (the big original one), but I'm getting tired of carrying those 6.6kg, and I'm starting to think of a new set up. So I thought maybe I should go for the HX, but I just very much need a lot of effects and options under my feet, so 6 footswitches won't be enough. My question is pretty simple, is it possible to add footswitches to the HX, in any way (midi, expression, usb...)? Thanks a lot ! Théo
