[sdiy] Kronkite Filter and sound generate without generators

[Mike Brown]

yeah... the company is Krohn Hite.  I have a dual filter that I've been
using for a new music project I'm working on (all industrial/military lab
equip)... it's two high pass/low pass filters that you can chain together
for band pass/notch filtering.  works OK, but I've got to hack it in order
to add resonance (feedback).

The interesting thing is that when you look inside, the main frequency knob
is connected to a long shaft with 4 gears that turn 4 smaller gears on 4 pot
shafts.  When I looked at this, I thought, "why didn't they just use a
quad-ganged pot?"  then I realized the gears were reduction gears and that
each of the 4 pots, depending on the number of teeth on the gears, could
have different reduction ratios.  man... that's something I never would have
dreamt up.

  I am reading electronic music guru Bulent Arel s letters from 40 years
ago.
  He says he found a way for to generate sound without generators.
  He says one kronkite filter , two tape and one amp are enough for to
generate complex sounds.
  May be I can build a mobile synthesizer for to generate sound on train or
on bus with walkmans.
  I do not know what is kronkite filter. I googled but I could not find
anything.
  Can you help me ? What is this arel technology and how it works . Where
can I find Kronkite filter ?

  Best ,
