The Kawai K2000, K5 and K5000 are all "additive" synthesisers. They are not
real additive synthesisers with discrete oscillators, but employ the closed
form method for a harmonic series using a trigonometric identity. It is the
tweaking of those input parameters that creates the filter-like effect.
I don't think the k5/2000 have any real filters at all, maybe in the K5000
which has an architecture a bit like
But those filters are pretty weak, simple remedial filters to top and
tail the spectrum. The real spectra shaping happens early in the chain,
(there's a group of envelopes that set the levels of the initial partials)
rather than later as per traditional subtractive synths.
