Hi Dave,
Sorry about the reference! On a different list (synth-DIY) every 6 months or
so someone gets the (generally good) idea that a bunch of DIYers should get
someone to make a run of "magical" chips -- sometimes it's SSM, CEM or even
new designs. After a few "great idea" postings someone will reply that it
costs about $40,000 to do a run -- end of thread. I believe that Paul has
expressed an interest in running both the CEM 3340 and CEM 3310 but that
$80,000 -- OUCH! Still, it's a good idea!
Thanks for the Emu Resonant Filter description. I vividly remember making
nice tuned percussive sounds with these, and I loved that UAF too. My
reference to the MS10 was in fact a MSnomer -- I don't know Korg stuff at
all. And thanks for your descriptions of the other MOTM VCF candidates,
interesting things ahead!
Quad VCA! I'd love to see one that could be configured as quad VCA, dual
stereo panner, dual crossfader kind of thing.
