cheers denis, thanks for your replies. i want to get something that does the same job as the shaper filter in the k2000 synth....but from reading a bit, i still don't have too much idea, but i think that maybe it's just a combination of a waveshaper and a filter.
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
[oscillator bank] | [shaper] | [post filter]
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.
i will read more.
