No one can do that Larry. It's not released yet! As for me - I'm sure that I could do a very entertaining show with well under 180 different rhythm styles. Back in the day - when I used stand alone drum machines, 20 or 30 patterns were plenty. I'm sure the 180 will be enough to "get by".
I'm waiting for one of these too, and Yamaha has been very helpful with every question I sent so far. Contact yamaha support with your queries. They are a great company to deal with.
