Thanks, Lindoz.
I am shocked to hear that the keyboard still has only 64 note polyphony.  Almost every other competitor has gone to 128 (or 126) note.  I hope the people you talked to were mistaken.  I have 64 note on my old KN5000 and if I use complex voicing and try to use technichord as well as composer rhythms it is easy to run out of notes.  I hate it when notes drop out. . .
