Anyone here got any time invested with the PSR S-550? I got asked a question today about the keyboard and couldn't give a difinitive answer to the person.

The S-550 does have a mixer function now.., but do those mixer features apply to user songs and can those edits be saved? I couldn't answer this question for the guy.., I do know it has a mixer, but don't know if it applies to user songs and if it can save those edits.


Hell with my history on this end of the PSR range you'd think I'd have an S-550 by now huh Considering I owned the PSR-540 and the PSR-550....
Thanks
