[sdiy] Anyone built a EFM SBM?

[harry]

HAH !!!

If Tom pre-patches something I don't like...  I UN-patch it ! That's
what X-acto knives are made for, and I buy my blades by the 100's.

OTOH... the normallized synth is a very good idea.  Turns out that
MOST times you will want a keyboard CV going to VCO's and maybe
VCF's... usually you want LFOs going to pulse widths, and VCO fm, and
maybe the filter... and Env Generators going to VCF and VCA.

Hey call me old fashioned...  ;^)
