62 voices are a snap to use up.
10 fingered chords,
layered sounds,
sustain pedal.......
you can bottom out on the second trigger of a big, fat chord if your foot is on the sustain. Forget about even turning on the arranger in this case !

In all fairness.... the polyphony on the PA80 is not too bad. If it is handled in the same way on this new piece....it might be ok, but it SHOULD have been improved at that price point.
