In addition to having delay instead of chorus, the Poly-800 II also had two
parameters for EQ. And it allowed the sequencer to be put into repeat mode.
The parameters were also shuffled a bit so parameter 41 didn't control the
same thing on both instruments.
My firsthand experience, many years ago, told me that the same settings
programmed into the Poly-800 and Poly-800 II produced sounds that were not
identical. And it wasn't just delay or chorus and EQ. There were subtle
differences.
