Dave,

The Yamaha 9000 can use as many as 8 tones per note (a sound made up of this amount). So if you play a two handed piano jazz style "chording", combined with strings, which could have 8 tones per note, then you will find out that the problem lies here. Example: a two handed chord of four notes (C E G C), layered by strings - containing 8 tones per note, would take up 80 notes poly - assuming the Piano had two notes for stereo sound (as is the norm). OK, 80 notes don't take all your PSR9000's Poly up - but play these chords in a arpeggiated fasion - and you have a different story. This is one of the problems I hear about the Yamaha 9000, you need more tones to make the desired sound, wereas other keyboards used 4 (mainly).

Your right there DNA
