hey rick, i have to disagree with you..the polyphony will drop if a particular "voice" uses more thn one sample,its the way synths have always worked, one oscillator = one voice (nowadays read "sample" for the word oscillator)...for example, usually the primo pianos are at least a couple of samples, so they can drop below the 32 notes (ie 16), HOWEVER, what most synth manufacturers do these days,and some of the algorithms they use are very complex and clever, with their samples is use velocity switching so that dropouts are nowwhere near as noticeable...i would be prepared to say if you used a voice that has more than 1 sample used, and could hit 17 notes at the same time with the same velocity you would get a drop out, this is assuming the voice creator has all the samples set to the same velocities (and just holding the sustain pedal and playing a note 17 times does not always work either for the same reason)...
the reason yammi's is not as noticeable as the casio is better voice allocation algorithms,but it still happens...
