Hi,
Ok, your keyboard has about 400 to 500 styles, how many of those do you actually use?

My case probably lucky to use 10 to 20 percent, if that. I mainly tend to play older style music out of the 40's 50's 60's, ie ballads, showtunes, jazz,
limited ballroom , Latin, pop and country.
I spent some time going thru my old music books and jotting down 2 to 3 suitable styles on my PSR for each of the songs. Definitely noticed some styles cropped up far more often than others in the same genre and other styles in that genre, I doubt I would ever use.
I concluded I must have favourites.
Did the same with the korg. Found a suitable style for the majority of the tunes, but there was definately the odd one that i had trouble finding as suitable a style for , as the one on my PSR.
Since I prefer playing my korg, it's downstairs, the PSR is upstairs in a spare room , I decided to convert the style I wanted.

Anybody else have a favourite style they really miss, or is it me being too picky about what I use.
