<DIV><SPAN class=183372522-12062023>So, I replaced a couple of the trimmers on
my Minimoog filter board -- the 1k and 500R trimmers were one-turn wonders,
and the 500R was actually a 470R cheapo flat trimmer that shorted out every
time I put a screwdriver in it. I replaced them with proper 18-turn
trimmers, and I think the circuit works better now.</SPAN></DIV>

<DIV><SPAN class=183372522-12062023>So, it seemed to work pretty well. I
was getting good filtering. It still didn't sound much like a Minimoog
to me. Also, I don't really like the way that it responds to high
resonance.</SPAN></DIV>
<DIV><SPAN class=183372522-12062023></SPAN> </DIV>
<DIV><SPAN class=183372522-12062023>Then I swapped the feedback resistors on
the input and output amplifiers (56k to 120k on the input, 120k to 56k on the
output) to make them both unity gain and drive the filter a bit more.
This certainly did not improve things. At the highest input attenuator
setting, the filter just sounds harsh and unpleasant. At a middle
setting, it sounds much better, but simply isn't loud enough. Hence,
that was a bad idea, and I will swap them back.</SPAN></DIV>
<DIV><SPAN class=183372522-12062023></SPAN> </DIV>
<DIV><SPAN class=183372522-12062023>Then, using the same VCO and ADSR
settings, I switched to my Dr. Octature Roland-style filter (but with gain
cells to eliminate signal droop with resonance) -- this filter simply sounds
brilliant (to me). It's loud, snappy, has much more pleasing resonance,
and "she responds like a limousine brought alive on the silver screen" to
incoming CV from the ADSR.</SPAN></DIV>
<DIV><SPAN class=183372522-12062023></SPAN> </DIV>
<DIV><SPAN class=183372522-12062023>Maybe I just don't need a Minimoog
filter. Or maybe there is still something wrong with it. I don't
know. I'm half done building the same board with 547/557 instead of
3904/3906. I'm going to finish that board and put it in the module to
see if it is any better. If not, then I will probably just abandon the
whole idea of building a Minimoog filter.</SPAN></DIV><BR>
