[sdiy] Polyphonic tonal disorder!

[karl dalen]

With the old polys some users complains about that the next note plated
dont sound like the previous played, it depends on the poly alg used
off course,whether its voice repeat or step trough all voices at each note
etc.Users of the Andromeda complaints about this particularely when
FM a filter from a VCO or VCO to VCO.I also remember DX7 users had some
minor issues about phase cancellation who could silence a particular note
down a bit.

Also people of single oscillator polys almost never complaints about
polyphonic tonal dissorder compared to 2 or more oscillator per voice polys.
Perhaps because that its easier to hear the disorder of 2 oscillators
for then same voice compared to the one oscillator based chord? No?

For example i never had read anywhere that synths based on CEM3394 would have
more of the disorder between notes in a chord then of lets say a JP8 or a P5?

But isn't this actually a normal situation to have certain amount of polyphonic
tonal disorder!?

Take a piano, a single note consist of several strings there are all kinds of
phase cancellations going during the time of the decay of the note played,or
take a guitarist playing a chord the higher notes dampens out more rapid then
the lower played in a chord. No?

Why is it so that just because its a synth the variation of timbrality in
a chord are seen as an abnormality? (Well if its to diverse its most likely.)
Because its to exact in tone compared to mechanical instruments?

What are *natural* sounding to a synth compared to whats defined as natural
sounding in a mechanical instrument in terms of polyphonic tonal disorder!?

Ideas folks?
