7/10/23 (alternate take) DIY Ray Wilson / MFOS synthesizer + Zerosum Inertia 6AS6 + Metasonix R-57


video upload by

"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."

7/22/23 SSL 1660 & 1310 + Zerosum Inertia Destructor Beam & VCA + TonAtelier Lauter EML 101 VCF


video upload by Cfpp0

"Call it a stiff swing thing. An alternate take from the version previously posted on 7/22/23 (captioned as 'swing thing') [posted here]. This sequence is the same, but sounds very different because the filter remains more open and isn’t quieting notes as much or fluctuating the focus through dynamics."

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."

video upload by Cfpp0

"Testing out The Matrix and this recording resulted. The feedbacking of the 1310 is worth archiving here. At the end I pull the audio cable from the 1660 and it’s CV continues to squeak the Destructor Beam while the 1310 feedbacks.

The Matrix is based on the Triadex Muse. Have to learn it, but this will be a cold dead hands module."

Zerosum Inertia - TVM23


video upload by NOISEBUG

"Brian @ Zerosum Inertia has really outdone himself this time. We will start calling him the Duke of Distortion around here. In the video we spice up a stock Korg Drumlogue beat with both channels of the TVM23. In the first half I am modulating it with the a-118-2 random signal clocked by the a-119 gate out. In the second half I am modulating it with a triangle wave from the a-111-3 at LFO and audio rates. Enjoy!"



via Noisebug

The TVM23 is an all analog audio processor for eurorack format synthesizers.

38mm rear depth.

18HP wide.

200 mA +12 average load, 500 mA on first power up.

50 mA -12.

The TVM23 is a dual processor with two separate channels independent from each other.

The heart of both channels is a 6CB6 pentode. Two matched 6CB6 pentodes are used.

The left channel utilizes distortion and feedback to create harmonic trills and waveshaping effects.

A genuine 5C1 vactrol is used for Control Voltage of the feedback.

The bottom left row of jacks are for the left channel.

The left knob is for the feedback, the center left knob is for the gain.

This channel seems to have more obvious effects when an audio source higher in frequency is inserted.

Hit the transpose up on your sequence a few times to see what I mean.

The right channel is a loud but clean tube VCA suitable for sweetening audio signals and processing

dynamic depth.

The 6CB6 is used for both audio processing as well as Control Voltage processing for this channel.

The bottom right row of jacks is for the right channel.

The right knob is the gain control for this tube VCA.

While most “VCA” modules are Voltage Controlled Attenuators, this is a Voltage Controlled Amplifier.

Your signal will come out louder than before when patching into this channel.

The left channel greatly benefits from having attenuation before entering.

Even better is placing a VCA before it to have dynamic depth control of the waveshaping and distortion effects.

You can use the right channel for this.

But most likely you already have a traditional VCA in your system so you can use what you have for attenuation/VCA duties before entering the left channel,

then patch the left channel into the right channel for it’s gain and audio sweetening effects.

I happen to have multiple tube VCA’s so I patch a tube VCA before the left channel and after the left channel for maximum character and saturation effects.

A lot of other people do too.

Whichever VCA you choose to use before entering the left channel you will be greatly rewarded with dynamic continuously variable distortion effects as the feedback loop is always changing.

Even before you insert control voltage into the feedback amount, the feedback loop is sensitive to the amount of signal feeding it and produces unique glitchy trills that sound like a video game.

Modulate the amount of attenuation with that VCA that goes before the left channel with a random voltage, sequencer, arpeggiator, envelope, sweeping LFO or clocked rhythmic gates.

I really like the NoiseRing and Wogglebug or sequence that is feeding my oscillators for this task.

For the right channel VCA a postive control voltage source from 1-10 volts with an onboard attenuator and variable response curve is recommended. Maths works great for this.

The VCA doesn’t use an exponential VCA chip or OTA like most other VCA’s, so the response curve is not a guaranteed linear or expo response and it is different with every tube used.

That is why it best to use a modulator with a variable curve and attenuation to dial in the best response.

It is recommended to start with all the knobs at full clockwise/around 5 o’clock and then work the knobs counter clockwise as you listen to the incoming audio source.

3-5 o’clock seems to be about the sweet spot for all the knobs but you will find hidden sounds everywhere.

The center knob controls gain, so if you bring it back too far counter clockwise that will attenuate the signal completely and no sound will come out. Center knob is usually best in the 3-5’oclock range.

The left and center knobs are part of a feedback network, so the settings between the two interact and manipulate the behavior and sound of the whole left channel in a symbiotic relationship.

They both effect the pitch effects that come from the feedback sounds.

Zerosum Inertia - 6AS6 Signal Combiner (eurorack valve mixer module)


video upload by NOISEBUG

"Zerosum Inertia 6AS6 Signal Combiner (valve mixer) in action.

The first section you can hear the comparison between a Doepfer mixer with 2 VCOs and then the 6AS6 directly after. Following that, you can hear the same patch through a filter, CV clicks / pops, and finally some simple rhythms all being mixed through the 6AS6.

Available on Noisebug.net and Reverb."

Zerosum Inertia - Cenotaph


video upload by NOISEBUG

https://www.noisebug.net/

"Alesis HR-16 (circuit bent) running through a @zerosum_inertia CENOTAPH.
Medium-Slow triangle LFO going to the CV input of the CENOTAPH. Drums dry on the right channel, CENOTAPH in the left channel.

The Cenotaph is device meant for processing modular level audio signals.

Line level or guitar level signals will work but need to be fed into a signal amplifier to get signal to modular levels before entering Cenotaph.

If low level signals are used the results will sound like a bit crusher and be less stable and predictable which sometimes sounds cool,

but overall it is recommended to stick with modular level signals like VCO waveforms straight out of the VCO.

The audio signal is fed into two 6CB6 pentodes then into a 4046 PLL and 4013 Divider.

Switchcraft 1/4” jacks and NOS military surplus tubes used.

Hand wired and through hole assembly, PCB manufacturing, enclosure drilling and metal work all done in USA.

For most stable results the left knob should be full clockwise/pointing to the right when third/right switch is in UP position. If center switch is in UP position then it doesn’t matter where left knob position is.

It is recommended to start with all 3 knobs in full clockwise position and all switches down.

Left knob controlls PLL level.

Left switch controls PLL behavior mode.

Center knob controls PLL frequency.

Center switch routes PLL INTO divider when up,

PLL and Divider are in parallel when center switch is down.

Right knob controls divider level.

Right switch selects divide down by 4 when down, divide by 2 when up.

Only use 12V DC Center positive + power source providing at least 1500 mA.

Use the power source that comes with Cenotaph."

Zerosum Inertia - BFK9000 Synthesizer Processor.


video upload by NOISEBUG

"The Zerosum Inertia is a synthesizer in a pedal/desktop format that offers some very interesting processing power for external signals. Thus unit can also be used on its own with the external cv input to create melodic synth lines and odd harmonic bass lines.

In this video we play the dry signal first and then bring in the BFK9000 for crushing and processing.

https://www.noisebug.net/products/zer..."



via Noisebug

"Loaded with New Old Stock JAN(Joint Army Navy) stamped 6CB6 pentodes designed to meet the high quality and reliability standards of the United States Military.
Manufactured by Sylvania, Philips, Radio Corporation Of America, and General Electric in the 1960’s-1980’s.

Switchcraft jacks and Alpha potentiometers flown on wires and firmly bolted to aluminum enclosure to avoid stress applied to circuit board.

Circuit board attached to enclosure with standoffs again to reduce stress and tension being applied to circuit board.
IC's are socketed, NOT soldered directly to circuit board to make easy replacement later if/when needed.
High quality long life high temperature low impedance electrolytic capacitors from Rubycon and United Chemi-Con.
5% NP0 capacitors in the power section and audio path.
5% metalized polypropylene in the PLL sections.
1% metal film resistors.
High quality 2A/25W medical grade 12v center postive DC power adapter is included. Only use 12v DC center positive power source included.
Engraved enclosure(NO STICKER!!!!)

The BFK9000 is an effects processor designed to process audio signals from your modular synthesizer.
VCO waveforms are an ideal source.
Guitar will also produce interesting results. It is recommended that you patch your guitar into a preamp with an envelope follower before the BFK9000. Crank the gain and then patch the envelope out into the CV input of the BFK9000.
The more gain you hit the audio input with the better the PLL's will track.

The higher the frequency the better the tracking.

Try cranking the PLL frequency to max then patching the output of the BFK9000 into a divider or pitch shifter down an octave or two.
Patch LFO's, audio rate VCO's, envelopes, envelope followers, sequencers, random voltages, rhythmic pulses into the CV input.

Signal flow of the BFK9000 is 2 6CB6 pentodes providing gain to drive 2 4046 Phase Locked Loop chips behaving as primitive oscillators in parallel, but not wired up like a traditional PLL you may be familiar with.
There is some conversation going on between the 2 4046's.....Something about an alien transmission of unknown origin scrambled with intermodulation and beating.

Frequency of PLL pitch and amount of PLL influence level for each 4046, 1 set on the left and 1 set on the right.
Tube gain is maxed at full gain, no knob.
1 switch for each PLL that controls the behavior characteristics of each PLL."
