how does the Taurus osc and filter differ from the Phatty?
"What separates the Taurus from the LP and most other monosynths is the feedback architecture of the filter. Like any tube guitar amp, the feedback architecture plays a large part in the "character" of the filter. This is why the Taurus sounds different from a minimoog from a rogue from a LP from a memorymoog from a voyager from a...
The Taurus filter has AC coupling between the VCF and VCA that happens to have an inherent bass boost. Due to the coupling being done at the feedback path, that creates some special interaction that gives the Taurus its voice. Boosting the bass EQ on your mixer does not get the same effect, it's sort of a dynamic bass boost.
Taurus also uses CA3080 OTAs which are NOT high fidelity components - they add some subtle distortion themselves, much like a tube. There's one in the filter feedback path and another used for the VCA. The Taurus is driven pretty hard in the filter. If you probe the output with a scope you can see the clipping of the ramp waveform. "
