Styles Vol. 23 – Blues Collection

This set of twelve styles is expressly dedicated to play specific songs.
These “song-styles" may not fit every type of chord you play, as they are,
contrary to generic styles supporting a complete set of chords, conceived
for particular songs and their harmony.

This archive contains two folders, respectively optimized for:
- Pa3X (also compatible with Pa3XLe, Pa900, Pa600, Pa300 and HAVIAN 30)
- Pa4X

The folder dedicated to Pa4X contains three less styles, since they are
already included among the standard musical resources.

Have fun!

any demos of the styles being played?

Thanks for this info, Don ...
This is going to be a busy week ... may not get to try these until after Christmas ...

Thanks again, Don ...

My 3x is sold, but the buyer didn't want it shipped until after 1/4/16, so I may load it in just to check out the styles.
PA4X is looking better all the time.

Bye bye S970......

Not yet. Always thinking though. IF they get it straightened out it would really suit my preferences better than the S970, but it is fine for now.

The free styles supplied by Korg are GREAT! All song-specific R&B styles. Mustang, Midnight, Soul Bros, Minnie Moocher, Everybody, Chain Chain Chain, Shake Your Tail Feather, Sweet Home Chicago and more. Great STS settings too.

Where can we hear them..?
