I already do this using the pedal mod buss. Variable mod depth, variable shaper, shaper source all do the same as your mod. What's the difference?

The Voyager is no Yamaha FM synth - very rudimentary FM algorithm, and the mod depth drifts with temperature and isn't calibrated or compensated. Mod ...

There was a component substitution during the Voyager production life that affected the tuning stability.

I am the original owner of an early Voyager, a Signature model. It has always been stable.

Years later I acquired a Voyager RME from the Moog Store. When I used it, the tuning was not stable ...

I bought a used Taurus II pedal set without the synth module. I wanted to MIDIfy the pedals to play Minitaur and have it double as a mic stand. I bought the Atlas MS-10CE mic stand - I removed the floor base and the 7/8" 27 threads per inch (TPI) tubing fit the pedal set. I've never seen the synth ...

Hey stranger.

I can't believe you modded a Signature Edition.

Foot Synth is not as in demand as we think it is.

I beg to differ.

In 2008, Moog offered to start T3 development if they received partial deposits from 250 customers. All 250 customers signed up in one month.

The initial T3 run was 1000 units. The demand was so good that they built another 500 ...

Relax, chicken little.

I'm a happy owner of many Moog products, starting in 1999 with two MF-104 delay pedals. Of the synths, I own a Signature Voyager (2002), Taurus 3 (2009), and Minitaur (2015). Seven MF pedals. Zero malfunctions.

I'm an EE and I can attest that the circuit assemblies are ...

No I haven't

Glad I acquired a pair of original MF-104 delays back in the day (the Big Briar models before the "m"/"z" models).

Some years later I acquired one of the first Voyagers (Signature model).

I put the filters in stereo mode, cranked the resonance so they oscillated, modulated both with S&H, routed ...

EMEAPP.org did a forensic engineering study on the Minimoog VCAs (yes the Minimoog has two VCAs, the 2nd one was for external control from the rear panel jack). Turns out during its original manufacture 1970 to 1981, there were three circuit versions of the VCAs (Gen 1, Gen 2, Gen 3). The ...

This is called "low note priority" meaning the pitch of a monophonic synth is determined by the lowest note pressed, and is normal in the Minimoog.

The bad news: the Minitaur editor has not been updated for a few years and may not work on new versions of Windows and OSX. I know that OSX High Sierra works, I keep my MacBook Pro running for that reason.

The good news: most functions can be adjusted from the Minitaur panel holding the GLIDE ...

"OTA" filters is a generic term. You can cascade a series of fixed mode OTA filters (IE lowpass) to realize a 12dB or 24dB lowpass filter.

The other "OTA" filter is the more common multimode filter (aka SVF=state variable filter), made famous in legacy Oberheim synths. These filters produce lowpass ...

One more thing: on all pictures i could find, the tempco resistor’s legs are bent in a very specific way. See picture. I wonder if this actually serves a purpose? Do i need to bend them in a similar fashion?


They are bent like that when the circuit boards were put through a solder flow machine ...

The Kelvin force/sense lines from the power supply terminate at the oscillator board. If the board connector flag(s) on any of these lines are open, the power supply malfunctions and causes oscillator bleed in the audio.

You can do a quick test by applying pressure on the oscillator circuit board ...
