"I built this many years ago. It's an emulation of a Moog Taurus 1, minus the oscillators.

The idea was to run another synthesizer thru the VCF and VCA of a Moog Taurus, to get the same increadible sound that only a Taurus 1 can normally provide (and which has never been accomplished by the Taurus 2, and I don't know about the Taurus 3 ...)

This worked great in combination with my Yamaha CS-50. Setting the CS-50's own filters wide open, and running it thru my Minotaurus, created an earth-shattering bass sound, that I only know from records that were using the original Taurus 1 Pedal.

For fairness' sake I have to meation that the CS-50's VCOs have a lot in common with the Taurus 1 VCOs, so you might not get 100% close to "the" sound with a synth that has rather thin-sounding VCOs to start with.

Nevertheless, the unique Filter/VCA configuration of the Taurus 1 that is built into the Minotaurus, will give tremendous enhancement to _any_ audio signal you run thru it.

I have carefully replicated even some of the so-called "flaws" of the original, such as the envelope level depending on the attack time setting, and the interaction of the various envelope parameters. There are no presets, however - just the manual controls.
Potentiometers are high quality types, and I haven't noticed any scratchy noise from them so far. Front panel is black anodized aluminium and milled - the lettering is engraved, not printed.

I never built this commercially - I have built this for myself when music electronics was still just a hobby for me."
