What is the difference between the oscillators, filter, ADSR, etc… on the Taurus vs the Voyager? The Taurus is supposed to be the “biggest bass ever” but what’s the difference between it and the Voyager (or a Minimoog)?
OBVIOUSLY the controls are far difference, but isn’t it the same Moog filter and oscillator basically? If there any sound that a Taurus can make that I can’t make with the Voyager or a Minimoog?
The main differences are that the Taurus filter is based off Bob’s original 904 modular filter. Also, the oscillators are only capable of sawtooth waveforms, and are V/Hz, not V/oct, so a Taurus will not play nice with other Moog gear as far as CV connectivity is concerned.
A Minimoog filter uses different transistors, as well as a different number of them, and different capacitors than the 904. As far as the envelopes go, they are not ADSR, but rather, ADS on both the Mini and Taurus.
A Voyager filter is loosely based on the Mini’s filter design. Subtle differences, but important ones, give the Taurus its unique sound. 
I’m thinking though that they’d be changing the scaling to v/oct for the TIII, unless I missed something?
You missed something. The Taurus III has the exact same sound engine as the Taurus I. Which means, V/Hz oscillators. E-mail Amos for clarification. 
Ah, but the TIII will have CV input for pitch so will that be v/oct?
With the availability of external CV sequencers out there, it would be foolish otherwise.
Amen to that.
I can tell you now that I don’t believe that it will have 1v/o response to a CV input on the osc.
It is totally based on the original designs so. I asked Amos about it and that is pretty much what he said to the best of his knowledge.
He said that the best bet in using it as a tracking oscillator woudl be to use the midi connections.

Well, if that’s how it’s gotta be to be like the originals, so be it. I’m sure there will be CV scaling options out there at some point. Plus, MIDI is pretty universal.
Bass… give me BASS!
Did I understand this correctly? Is there no way to get pitch tracking to work on the Taurus 3 via Voyager Pitch CV out? How about via the CP-251? Why was the Pitch CV input included on the Taurus 3 if no Moog synths can interface with it via CV?
Go to the Taurus 3 microsite - there is a chart posted by Greg AE (writer of many Moog owner’s manuals) under the “images” section which shows how to control the Taurus 3 via MIDI using a Voyager, but there is no mention of control voltage connections or of actual control voltage input/output levels.
As far as the bass sounds go, I own a T-3 and a Phatty, and used to own a Voyager, and while the the Taurus is the undisputed king of bass (the Voyager is no sloutch, either), I prefer the bass sounds you can get out of a Phatty more than the Voyager, mainly due to the overdrive section on the Phatty. I’m hoping Moog will eventually add the LP overdrive circuit to the Voyager, and when they do, I’ll have to buy one again.
Page 12 of the manual says
“The PITCH jack on the side-panel is a CV input for external control of the oscillator pitch. This input
controls the frequencies of both oscillators. A 1-volt change of this voltage will change the pitch by
NOMINALLY one octave. The jack accepts 0 to +5 volts, or an expression pedal like the Moog EP-2.”
I could find no mention of Hz/octave in my perusal of the manual.
The internal VCOs are v/hz, like the original T1.
The PITCH jack is v/oct, like the Voyager.
So will the Taurus track the Voyager’s CV out?
The Taurus should track at exactly one octave per volt applied to the Pitch CV input jack. The conversion from V/Oct (Pitch CV) to Hz/V (linear internal oscillators) is done internally.
Oh man that is news to my ears.
There were some of us that were really wondering, and even you said that Pitch CV slaving of the Taurus would be better suited to Midi.
Man,now I really want my unit.
