Hey guys. Just need some help with the orientation to the xs's buttons. For now at least, I need to know where the function keys (f1, f2, etc) are located so I can configure the xs to use usb as its midi in and out ports. In adition, I need to know where the sf keys are. Once I hit sf2 for the midi page, how far do I have to spin the dial until I get to the usb option? And once I get there, how do I accept that choice and where is the store button? Also, where are the inc and dec buttons? Thanks Jes
