Hello,
I was able to load one (1) music STYLE from a USB stick into my PSR S770 this past weekend.
Thrilled (finally) with this first-time success.
So I went to the web at PSR Tutorial site and loaded (unzipped where necessary) dozens of more music STYLES.
I can not find instructions in either the Owners Manual or Reference Guide for how to "step-by-step"
(make the required button presses on my S770) to load these STYLES from my USB stick into the new instrument.
Can you help me please? Many thanks.
