hi all,
Well I am getting my bandpass filters mounted up and runinng.
I have rev1 boards. The freq pots works as expected, but the Q
or bandwitdh pot seems to have little effect. I read on the list
that you can drop the 4k7 res. inline to 2k2 or1k...anyone done
that? I am looking for more of an "effect" from the res pot.
also - any suggestion for a simple summer, passive or active for
the combined output of the 3 bpf? I could use an op amp summer, but
can I do the same with a transistor and just fly the leads n
the jack?
the saw pahsar/mangle is next ont he beach to build, after I clean up
a bit....
oh, using the plfo modulating a filter feed by a tri wave and a
little echo I got a very nice digderidoo type sound. added a little
wave multiplier on a slooow sweep to get a growl in there too.
meditation....
