Hi,
I'm new on this forum so I beg your pardon for introducing this topic that's not new; still I'm searching help since I can't find the answers I'm looking for.
Yamaha Clavinova CVP503 is a powerfull instrument, but Yamaha manuals, either the User Manual than the Reference Manual, are very poor.
On internet there is people that sells "Easy Manuals" for quite a big price, but it's impossible to know if those manuals are just a review of the standard manuals, maybe written in a easiest style, or if they are really serious and technical manuals. Some user writes that if you want to go deep inside the possibilities of that instrument, those manuals are useless.
In other forums i saw many users having this problem, and not finding a good answer. That's way I'm suggesting this new (but not new)topic.
Is there anyone that knows a book (not a e-tutorials, or e-course or similar to buy), or that himself really knows this instrument and that could give a usefull and complete answer to simple questions, like, for instance, this one:

how can I change the volume (velocity) of any of the different pads (lyke cimbals, snare etc.) of a drum set and save this new setting as a new style?

I will really appreciate any help you could give.
Thanks a lot, and please forgive my poor english.
Edoardo
