[sdiy] Polivoks filter principle questions

[julian schmidt]

somehow my reply got lost...
here it is again:

I had another look at some datasheets for programmable op amps used in 
polivoks clones.
It seems as the cut off frequency is decreased, using Iset pin, the slew 
rate of the OP is also decreased.
for example looking at the lm4250 that is used in the mutable 
instruments clone
http://www.ti.com/lit/ds/symlink/lm4250.pdf - page 7
we see that if the gain bandwidth is reduced from to 10 kHz the slew 
rate already goes down to ~0.002 V/us.
