I don't have Cubase myself, but that utility should be helpful for people who do.
Cakewalk Music Creator 6 Touch looks very interesting! As for SONARX3-- or other DAWs-- I'm inclined to want to get the ultimate version so I get the most virtual instruments (even if I never actually use nine-tenths of them), although of course that always translates into "mo moolah," which in turn translates into "Maybe I can sweet talk someone into buying it for me for Christmas"!

Not that I need yet another DAW, although they are fun to collect (at least, if they're free or cheap).
I haven't tried Reaper yet, but everybody keeps talking about it, so I guess I really should check it out.
I do have Anvil Studio, but I haven't purchased any of the add-on modules yet, and I think using custom instrument files requires purchasing a module.
