Side note: the auction description ends mentioning the Arturia Minibrute SE. As always be careful. When buying on eBay, be sure you actually buy through eBay for the buyer protection. If you take it offline for a "deal" you assume the risk.

"The Tetrax Organ follows a lineage of electronic musical instruments based on touch. It was redesigned once, as. It has four wooden bars that you press to express four oscillators within. Each oscillator has its own fine tuning slider, embedded right within its bar. Also, there is are two master pitch knobs, and two master chaos knobs. Each master chaos knob makes the instrument go from pure sawtooth tones to a nest of noise. It does this by gradually increasing modulation from one oscillator to the next in a circular pattern. The reason there are two of each knobs: the Tetrax is all about timbre modulation, by changing the upslope and downslope of triangle waves separately. So, for master pitch and chaos, there is a separate upwards and downwards knob. In general, Tetrax is for funky bass and complex tones, while is for sweet melodies. Of course they all have noise available at any point!

There are 28 modulation points brought forth as banana jacks. They are arranged in four columns, representing the four bars. Their layout is shifted diagonally, to allow inputs in proximity to outputs. This is for touch-playability; you can make banana jack metal studs that can be squished by hand to gesture-patch the instrument. Inputs are cool colors: blue, green, and grey. Outputs are hot colors: red and orange. The grey jacks are parallel inputs with the master knobs: the two on the left are for master pitch, the right two are master chaos. The color allotment for each bar is as follows:
Two orange jacks, representing the press and release gestures on that bar in voltage.
One red jack, which is the pure triangle output of that oscillator.
Two green jacks, that are "glitch" inputs. They cause the boundary conditions of each oscillator to wire to the output of another. A modulation inspired by circuit bending.
One blue jack, an fm modulation input for that oscillator.
The Tetrax organ has a stereo-mini output on the back. This is because each bar, outputs in different channels during the press/release cycle. In addition to the stereo-mini jack, it has an power switch, and optional built-in batteries, or an external, 9volt battery snap."

"This synth is in incredible condition for 42 years old. Cosmetically it has some signs of wear and a hand full of the original knobs have been replaced as you can see in the photos. Everything works. Not only does everything work, I have also retrofitted the synth with a Kenton CV kit so there is cv control over Hz/V, gate, and filter. Sequencing this machines notes and filter is INSANE. You can integrate this with an analog sequencer or kenton midi to cv box (or any other cv source even a korg sq-1). Last year I also had Rosen Sound in Los Angeles install a midiplant so not only can you control the synth via cv, you can also trigger notes via the midi port on the back with a quick flip of a rear toggle switch. I personally still prefer the control and resolution of straight cv. The synth is really incredible and I've sampled more sounds from it than any other instrument I own. Have a listen to some demos on youtube if you aren't familiar. This machine is from another planet. The serial number is 770073 and it was one of the first units produced. Extremely rare. Also including a custom made dust cover."

Rush - Tom Sawyer Bass Growl | Tutorial with Korg Minilogue, No Talking

Published on Sep 16, 2018 Anodyne Institute

"What's happening here?

We adjust our First Oscillator to be a number of octaves lower than its default pitch. We introduce Oscillator Two an octave above the first, barely mixing it in so that it doesn't overwhelm the deep bass of the first. We slightly detune the second oscillator to add subtle animation and fluffiness.

We switch from Polyphonic mode to Unison mode. All of the oscillators are now stacked for one massive voice. We again slightly detune all of these oscillators, using the contextual Voice Mode Depth knob, for more animation and fluffiness. (This is caused by all of these waveforms subtly cancelling each other out at different points, creating more of a bass 'pad' than a solid bass tone.)

We move on to the filter. We use the filter in 2-pole mode, for a wider range of resonance and preservation of bass; the 4-pole filter can cut out bass frequencies at higher resonance because the curve is so steep. (Plus we think that Rush used an Oberheim OB-X for this sound, and it uses a 2-pole filter as well!) We add resonance to the filter, set our 'target cutoff frequency' manually, then add the modulation envelope's contribution to the filter. This automates the signature filter sweep so that we don't need to play it by hand.

The length of the decay on the filter envelope and how deeply it is applied, combined with the resonance amount and the fuzzy unison voice, are some of the most key ingredients here.

Finally, we add echo from the delay section. Using the high pass filter on the echoes is very useful in preventing such thick bass frequencies from getting muddy, and the repeats (feedback amount) really accentuate the filter sweep.

We fine-tune some of these key parameters: resonance, envelope decay length, envelope modulation depth. *We initially made the attack of the filter envelope a little too long and it produces a sharp, liquid pop.* Welp, now you have the opportunity to do better!
