The filter cutoff frequency varied enormously between
6581 chips, they fixed
that completely in the 8580. While also changing its character a lot. I
wouldn't say it's downgraded, it's good to have both versions.
I suspect the SID upgrade was an attempt to get Commodore into the
synth market, even if just a supplier of the chips. Just about every
synth marker eyed the 6581 to some extent, but they all found the
variations found in the chips to be intolerable.
But, by the time the 8580 happened, so did the DX7.
