Thanks for the clip Eric, quite an interesting function. Alas obviously only on the newer s970, not my older s950. Darn.
Indeed, its on the 970, 770 and 670...
A very fun addition to the psr s series...
I am looking forward to see this on the next tyros, maybe they will even expand this new part, that comes with two knobs, and deejay styles and parts of a chordsequencer...
