Hi Victor...good to hear from you again,
Yes, I think you can use the Nano very nicely to control the Yamaha style elements.

As far a styles/sounds..I am very happy with the styles I have on the PA...sometimes I may want to use a VSTi or other (Kurzweil PC2R) sounds instead of one on the PA..No problem to do it as we can just use EXTERNAL mode on that track, key in bank/pgm and off we go...Neat. (CC0, CC32, PG chg). Save that in a songbook entry and good to go anytime.
