Technically, no. Polyphony only means that you can play that many number of notes at the same time, so if your digital piano has a 64-note polyphony, it can play as much as 64 notes at a time. 128 notes for a 128-note polyphony. 64-notes is plenty for most people, and it's usually cheaper than 128.
