Bungle: I just checked your earlier post: So you *do* already have tons of patches. Great. As for the XP30 community not really having much of a presence "yet": Many are on the JV/XP list, and--quite frankly--let's face it, the XP30 has been out a long time now and is already no longer really part of Roland's flagship synths. BTW: I don't know of any Roland-specific book on programming either, though I think some people from the JV/XP list posted some tutorials at someone's site once upon a time (maybe Ben Tubb's site). Anyway: good luck.
