Hi Audrey and John,
PSR Tutorial is a great site for all kinds of Yamaha info, some wonderful styles. John I don't have any software to bring the Yamaha styles to the KN7000. I simply record each part of the style in the key of C to make a MIDI file and then load it into the 7K. Go to Program Menu - Composer - Seq to Composer Copy. Select the measures and assign parts based on the MIDI file location and put together the composer style.
This is a slow process, but it has brought me styles that sound great with the Technics voices.
