Taurus

[Haible Juergen]

Different transistors (shouldn't matter). As close as I can think of -
probably too close. The envelopes are *very* limited. Limited to
short (but not ultra short) VCF attack times, and limited in that
the VCA cannot really have very slow release time.
It's surprising that the original Taurus sounds so good despite
these envelopes (;->). There's one feature, though; about these EGs:
The VCF modulation grows stronger when you're playing faster.

It sounds good, a bit different than my Minimoog clone, but I still like
SSM2040 filters better. I have yet to test it with two  V/Hz-VCOs.
With the CS-50, I have either one VCO (too thin) or 4 VCOs (killer,
but not like Taurus.)

I've only run tests with the open pcb so far, which is a limitation for
sure.
(The reso pot is still a linear trimmpot - but I'll get the right pot from
MAM.
Thanks to all who have responded to the pot question !)
