The PSR-4500/4600 were nearly identical, except for a few cosmetics...although the 4600 had several different accompaniment styles.

They both used the D.A.S.S. which was FM and AWM simply combined without Vectors.

I used to like the unique "roll bars" that were situated under the keyboard and allowed for pitch bend and modulation...pretty cool!
