Why not?

Perhaps we are referring to different things. I was talking about the numbe=
r of
steps in a filter cutoff parameter - if you only have 7 bits in the filter =
cutoff setting
then you can only select 127 discrete cutoff frequencies. If you overdrive =
the filter
emphasis then it should turn into something close to a sinewave oscillator =
at the
frequency of the cutoff - the steps in the frequencies become audible which=
was a
ongoing complaint against these systems. The issue is that if you want to d=
etune
the filter oscillating frequencies by a 0.1 HZ to get some phasing then you=
are out
of luck since the cutoff steps are too big. The same is true if you want to=
use this
filter as an extra oscillator (something that a lot of people did on the bi=
g synths to
get hammond sounds) then it doesn't tune that well=2Cespecially at the high=
er=20
frequencies where the filter was used as if it were another drawbar.

It doesn't mean the synth will not sound good=2C there are just some things=
that it
will not be able to do.
