size=2>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).</FONT></SPAN></DIV>

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.</FONT></SPAN></DIV>

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