OP-1 Quick Ref Guide

I just spotted this and realised the OP-1 Cookbook is still in the iTunes Bookstore top 50 for Arts & entertainment - Music. Freddie Mercury holding it off !!!

Taking feedback and looking at the interest i might have a look into transporting it to other platforms other than iPad / Mac while i have some time off over christmas. No promises but any comments welcome.
