On the topic of polyphony ... a couple of things ... on my Tyros3 then Tyros5, I only remember one situation that caused notes to noticeably drop out. I'll have to see if I can re-create it and record it. I think it was one of the styles like "Epic Ballad" or similar, that was very thickly orchestrated ... and had cymbal rolls and/or tympani rolls ... when I coupled that with a thick sound in my right hand (all three R1+R2+R3 all acive, and a sound in LEFT also) - then when I called for a Fill In, I think in Variation C which had that cymbol-roll or tympani roll - all this together did cause a bunch of notes to suddenly truncate. Other than that, I don't recall noticing it happen, but I understand how it could.

Also, Yamaha has done a nice thing on the newest CVP pianos (CVP-609 in particular), where there are TWO sound engines - one for pianos and a few other sounds, at 128 note polyphony, I think they call this the "Natural!" sounds. PLUS another sound engine that is sort a "Tyros4 in the box" that is 128 more notes of polyphony. This helps spread the polyphony around (total of 256 notes of polyphony).

I think they might have planned to have this on the Tyros5 also, as the Data List for the Tyros5 originally listed a whole bunch of "Natural!" voices, but turns out the Tyros5 in fact had no "Natural!" voices. I wonder if they planned for it, but didn't get it all to work in time for the ship date for the T5?

If that's the case, perhaps the Tyros6 will have the TWO sound engines, and thus 256 note polyphony???
