is the psr 975 vocal armony different from the one of psr 950

[acorrias]

Hi
I own an "old" psr s950 and cannot understand if the vocal harmony 2 of psr 950 is different form the one of the new psr 975 and the pst 970. I saw some videos where the new keyboard is played with vocoder effect as Moroder or Daft Punk. I saw presets in my psr s950 called vocoder but the effect seems different

Please if there is some expert, would he explain the real difference?

thanks in advance
Alex

No one has responded as of yet.

To my understanding the current VH2, which first appeared in the S950, is the most up to date harmonizer used by all Yamaha keyboards since that model.
