Hi Stephen,
not the newer Yammies unfortunately, & I don't think my one Man Band software has the newer settings.
I do fiddle around with the Yammie styles for my conversions to korg in midifile format, so I can tell just how far they've developed in the last few years.
My psr1500 ( & earlier ) were relatively easy ( TIME CONSUMING, but simple) to convert, I did a couple of T3's, whole new ball game.
As a Yamaha owner, you must have noticed a big improvement in the styles themselves ( not just the voices). If you've got any of the early styles like for a psr1500, or psr2000, try muting the other tracks & just listen to a strumming guitar chord, then listen to a new T4 style .Not a rehash of a style that yammie has included in keyboard after keyboard, a brand newie, & see if there's a difference in the way it now plays a strumming guitar , I somehow doubt it still uses those early, chord voicings.

The style player in my many keyboards over the years has always facinated me. I've had Technics, Yamaha, Roland, Ketron & Korg.
Technics KN7 styles system ( transposition tables & settings )was truly amazing. Unfortunately didn't fully sink in till I worked out how some of the other keyboards worked.
