I remember those...they had the roll bars under the keys, in front...very futuristic looking...there was a PSR-4500 as well, but the 4600 was the better instrument by far....they used DASS synthesis, and they were great sounding instruments.

Still, the E-series, from Roland, was very popular...they just sounded better, especially the styles.

Come to think of it, I do remember playing a Korg...it was an I-series...an I-3, I believe...61 keys...it had a wicked Sax sound, and the styles could easily be revoiced...you could have a big band arrangement of a heavy rock style, or a rock band playing a Viennese waltz.

It was my only experience with things Korgian as far as newer arrangers went, although I did play an SAS-20(?) that was a trade in at the store where I worked...it was pretty cool.
