"2/27/25 (new 5U) SSL 1660 + Blue Lantern Mixer/VCA/Decay + Zerosum Inertia Scorpion Tail + CXM 1978

This was a test of the new Blue Lantern Mixer/VCA/Decay module that was just released in 5U Moog Synthesizers.com American Format. The Synthetic Sound Labs 1660 audio output goes through the Zerosum Inertia Scorpion Tail, for some waveform defects and saturation, then into channel one on the Blue Lantern. The SSL 1660 gate output is triggering the Blue Lantern VCA. The VCA output goes to the Mackie Onyx 1640 with reverb blended on the CXM 1978. As you can hear there is white noise that can be blended in with the mixed signals. And the “Spectral” switch I’m flipping really sounds great!"

"We sold the Roland System 100 Model 102 synthesizer, the Moog Labyrinth, the Seeburg Rhythm Prince, and a few other things recently, so there a few interesting pieces coming in, like this Zerosum Inertia Voltage Controlled Annihilation. We normally purchase Zerosum Inertia products brand new unless they’re discontinued, but this used purchase supported an animal in need. Anyways, this was a first test, mostly just to hear it sizzle and fry, using a Lana 212 VCO through a Roland 121 VCF into the Zerosum VCA, with a Roland 140 envelope driving the VCA CV."

"First test with Zerosum Inertias recreation of the Metasonnix R52 multimode filter.

Signal chain is:
Hertz Donut MK3 - Metasonix RK2 - ZI52 - TVM23 - Audio Interface - FabFilter Plugins"

The zi52 is a recreation of the metasonix r52.

This is a zerosum inertia product with permission granted from metasonix.

Metasonix wants it clear that zerosum inertia is responsible for the questions, support and manufacturing of the product.

It is a resonant equalizer/resonator/filter useful for tone sculpting and scream generation when at high resonance settings.

Two 12aw6 pentodes are responsible for the character of the sounds processed and created.

12aw6 have an amplification factor of 42 mu compared to 36 that a 12au6 provides.

The 12aw6 has a distinct resonance tone that is not found with a 12au6.

It is fizzley and sounds like a fuzzbox at max resonance.

Backing off the resonance allows for smooth filtering without oscillations or squeals.

The resonance is technically a gain function and needs to be up a bit for sound to pass through.

The input knob affects the resonance behavior and general overal sound of filtering heard.

To hear the filtering effect, backing counter clockwise on the input level is needed.

Increasing the input level creates more saturation but overloads the filter and less 'filtering"'is heard.

The Scorpion Tail from Zerosum Inertia

video upload by NOISEBUG

"The Scorpion Tail from Zerosum Inertia is absolutely radical!

Check it out and then go to https://www.noisebug.net/products/zer...
For ordering info"

The Scorpion Tail 5U synthesizer module for dotcom systems is an audio signal processor designed to amplify, distort and create new waveshapes by processing audio through a 19EZ8 triple triode and A1B neon lamp.

The signal flow of the module is 3 gain stages in series fed into the neon lamp.
The audio result sounds like 3 waveshapers in series with the neon lamp as a fourth waveshaper or as a resonator/oscillator that tracks to incoming audio.
When the neon knob is at maximum setting clockwise it oscillates.
When neon knob is turned counter clockwise more distortion and waveshaping and lower frequency audio manipulation happens.
When gain stage knobs are full clockwise this creates a very crisp, clean and low noise loud amplifier.
When gain stage knobs are turned opposite of eachother and counter clockwise this creates oscillations and wavemangling distortion.

CV is handled by an SR3 vactrol for slewy slappy liquidy modulation behavior of the waveshapers instability.

It is recommended to start with all knobs full clockwise/about 5 o’clock position and then work the knobs backwards slowly while observing the sounds.

The sweet spot for the offset knob is about 2-3 o’clock when no CV is applied.
Then full counter clockwise when CV is applied.
When no CV is applied the offset knob manually sweeps the instability of the 3 waveshaper gain stages.
When CV is applied the offset adjusts the response of the incoming CV.
Work that offset knob when applying CV.
The most interesting and bizarre mangled sounds come when the first gain stage is barely letting audio through.
The loudest and less scrambled sounds are found when all gain stage knobs are full clockwise and offset is about 2-3 o’clock.

There are so many hidden sounds in this module you will have to record them before they disappear and warp into a new sound.
The intended use of this module is to process audio waveforms from an oscillator.
There is a lot of gain so you will most likely want to place this in the middle of the chain with a voltage controlled attenuator at the end of the chain to control final volume and dynamics.

Very interesting results are found when also processing synthetic percussion and rhythmic beats and sequences.

Erebus Orifice from Zerosum Inertia

video upload by NOISEBUG

"A. Description:
The Erebus Orifice is a synthesizer module designed for processing audio signals.
It is also capable of generating audio which can be manipulated with Control Voltage.
The Control Voltage is made possible with the help of a VTL5C3 vactrol.
Modulation sources providing 0-10v signals are ideal, 0-5v signals will work too.
The basic design of the Erebus Orifice is a tube preamplifier with a tweaked feedback path.


B. Inputs, Outputs and Controls
There are 3 jacks available:
Enter is where audio signals are to be inserted.
Exit is where audio leaves the module.
CV is where Control Voltage signals are to be inserted.
There are 2 knobs available:
Top knob controls feedback.
Bottom knob controls gain.
The purpose of a knob is to manipulate the behavior of the audio signal being heard.
Twist the knobs and observe the results.
Choose your own adventure.
There are only 2 directions to go: left or right.

C. Power details
The tube used is a 7 pin 6CB6 sharp cutoff pentode.
The use of the tube requires the user to have a power source capable of providing
150 mA of +5 and 30 mA of + and -15 on average load.
The plate voltage is 48 volts and there is no risk of injuring the user.

D. Mounting details
The module is designed to take up 1 space in a synthesizers.com cabinet
sometimes referred to as "MU" for Moog Unit.
The Erebus Orifice is not designed to recreate or emulate such circuits.
It is an addition to the large format modular system, not a clone of any other design.
Rear depth of the module is a shallow 1.9 inches.
Power connection is provided by a 6 pin MTA connector  compatible with Synthesizers.com power distribution systems and QPS1 and QPS3 supplies.
The panel is 3mm thick aluminum with machine engraved print.
Panel will not flex or bend and print will not flake off."

4/4/24 (swarm) Gieskes Klok & No Drum + Zerosum Inertia PLXNA2 + OAM Uncertainty + Lexicon PCM 70

video upload by Cfpp0

"Butterflies, bats, 16mm swarm: Gieskes Klok modulates itself and No Drum and Olivia Artz Modular Uncertainty, which modulates No Drum, while Klok gates No Drum."

You cand find additional Gieskes Kok module posts here.

This appears to be the first post to feature Olivia Artz Modular. Details on their modules follow via Perfect Circuit and Noisebug.

"Uncertainty from Olivia Artz Modular is a 2hp coin toss module; it is open source, with new, user-swappable firmware being developed. So, it will continue to grow and offer new functionality!

In the standard firmware, the top input accepts gates, triggers, or any signal between -5V and +5V. Based on whether the input is positive or negative, it uses two different types of logic to produce gates at the corresponding eight outputs. If the input is above +1V, then the module does eight differently-weighted "coin tosses"—one for each output. If the outcome of the toss is "heads," a +5V signal is output for as long as the input stays above 1V. If the input signal is -1V or lower, a slightly different coin toss algorithm is used, where the outputs are paired—if the result of the toss is "heads," the upper output of the pair in question sends out a signal, and if it's "tails," the lower outputs sends out a signal.

Alternate firmwares are available for free, and loading them is as easy as plugging in your module via the rear PCB USB connection, dragging on a file, and you're done. The first new official firmware is a VU meter—with the panel LEDs displaying the current voltage level, and each LED getting a dedicated gate output—somewhat like a multi-window comparator! Olivia Artz's Uncertainty module is a great way to add chance operations to your rack without sacrificing space.

"This video contains more filter sweeps than the video previously posted on 7/10/23, and the MFOS filter cutoff settings cause the Zerosum Inertia 6AS6 Signal Combiner to generate different rhythms than in the previous video. Two MFOS LFOs (at audio rate) go to Zerosum Inertia 6AS6, get combined, go to the MFOS filter, and go one channel on the R-57."

"Call it a stiff swing thing. An alternate take from the version previously posted on 7/22/23 (captioned as 'swing thing') [posted here].

8/9/23 .com Q123 (440Hz) SSL 1660 (gate rest) 1310 + LWSS + MooSonics + Zerosum Inertia (oscillate)

video upload by Cfpp0

"Same SSL 1660 sequence (except for the D slider position) as in the previous video, but with the 1660 gate set to rest, so that it deviates from steady 1/8th notes (the SSL 1310 is swinging them into 16ths). The Synthesizers.com Q123 Standards module (which has an oscillator that produces 440Hz to reference for tuning) runs into Zerosum Inertia The Destructor Beam, but self-oscillating and tuned higher than 440Hz. So flipping the 440Hz switch on or off selects either 440Hz or tube feedback and provides two tones to drone against the SSL 1660 sequence."

8/2/23 Yamaha DD-10 + Metasonix RK8 & R-57 + Zerosum Inertia 6AS6 + Synthwerks FSR-2P + PCM 70

video upload by Cfpp0

"Yamaha DD-10 plays its 'Computer Swing' beat, with Intro/Fill 2.

The left output of the Yamaha goes straight into the audio in on the RK8. The right output of the Yamaha goes to the Synthwerks FSR-2P and then into CV in on the RK8 (though it is not used in this video). The mix audio out of the RK8 goes to the Mazzatron pass through to the EWI bay to the Samson bay to the Mackie Onyx 16:4, where it gets PCM 70 Gated palate on an aux. Two bands from the RK8 go to the Zerosum Inertia 6AS6 (it matters which goes to which input). The 6AS6 out goes to the Synthwerks FSR-2P and then to the R-57 and through the Mazzatron pass through into the EWI bay into the Samson bay into the Mackie. Towards the end, it actually sounds better when the Yamaha volume is reduced, so more or less input gain is critical to the RK8 like it is with Metasonix TM and TX boxes."
