I've had all my recordings in the last year and a half produced from my PSR S750. I originally ordered the 950 and the Vocal harmony was so far below my standards I figured out how to make the 750 work with my stand alone harmonizer. Good think I know them well at the music store!

and... FAITHFUL

I'm miked into my Digitech Vocalist 4 which connects to the keyboard with a simple stereo mini plug cable from headphone out on my harmonizer to AUX IN on the 750.

I would highly recommend this keyboard.

God Bless,
Don
