I am surprised, I found (still find) the XR a LOT harder to set up (but then "I'm a man of simple tastes.." or a simple man with no taste!)
For me I7 went: install driver, plug audio (to line mixers), MIDI & USB cables (I'm AC/DC when it comes to MIDI

), set I7 USB to Vender (mainly becasue of the EDITORS need), and have had zero use issues so far?
[but after working with Motif's and now Montage's, non-intuitive USB interface to PC it's all simple]
GLAD Roland provided .ins file (too lazy to build them myself anymore, at last from scratch),
I did install BOTH the long available and FREE full Editor from Roland Clan forum user K_take, and the (FINALLY) provided by Roland FULL V2 Windows Editor for the I7.
(Given how Roland and Sonar were married for a while it surprised me when they ONLY provided an Apple editor for so long. Actually one BIG reason I HELD off so long)
