miden, you are absolutely correct. I guess I can't count to 32.

I was hearing some things with the pedal that made me think the polyphony was 32 while playing stereo piano sounds. Then I thought "maybe that's not an accurate way to go about this," so I got some hard cover books and an old picture frame. With the picture frame, I can play 24 white keys at the same time.

Stereo pianos (Voices #1, #2 and #3): If I play and hold down a big Db, then play and release 24 picture-frame notes, the Db is no longer playing. It doesn't matter which 24 notes I play with the picture frame.

Also, if I play 10 "book" notes at a time, followed by 10 more book notes, then hold down one of the 20 notes with my finger before releasing the other 19, the finger note may not be playing. That indicates it stopped playing when the second group of 10 notes started. The notes that cut out usually seem to be the top four notes out of the first group of 10.

Mono piano (the first two XG grand pianos, voices #140 & #141): Now if I play and hold down a Db, then play and release 24 picture-frame notes, the Db is still playing. And with the two book test, I can't find any notes that cut out. So I guess this has the true 32 note polyphony.

Piano/strings XG combination (voice #142): Back to 16 note polyphony. Same test results as for stereo pianos.

Stereo piano/strings combo (voice #1 dualed with string ensemble): 8 note polyphony. By standing the book on end I can play 7 or 8 white keys at a time, depending on how I place it.

If I play a Db, then play and release 7 book notes, the Db is still playing. If I play the Db then play and release 8 book notes, Db always cuts out.

I'm sorry I made negative comments about the new Privia PX-575R. It looks like a very exciting instrument! I like the 120 user tones. My YPG-625 doesn't have any synth functions. I hope the speakers turn out to be better than the PX-555R.

Don't know what's going on with the pedal on the YPG-625. Might take another month of tests to figure that out.
