I would not be surprised at all...Yamaha has had polyphony problems in the past..My experience with a PSR320..even though it was only 32 note polyphony..just muted all sounds for several seconds (unacceptable)..they needed voice allocation like even the 24 voice Sound canvas...

The other was the flagship 9000 Pro and PSR9000...they had 128 voice polyphony ( maybe it should have said elements)...but strings and piano with a hold pedal..produced poor drop out..without allocation (again)....

I thought Yamaha might have finally fixed this...but apparently not ..by this report..and I do believe the report...

Before the Yamaha supporters chime in..that it works for them...wouldn't you want an allocation system that sets priorities?

Put it in words that have condemned Audya...A big chunk of money..it should work as a top keyboard..
