AI250 BXR Eurorack Test Equipment Mangling CV Edition

video upload by AI Synthesis

"A quick Demo video running an envelope and sine wave LFO into the BXR and getting variations of mangled control voltage. The audio is a static Sawtooth wave being filtered, and the filter being modulated by the mangled CV. For context, the CV input sources are all either a simple Saw style ADSR or sine wave.

The AI250 BXR is a eurorack module inspired by vintage nuclear test equipment. It can be used as an audio mangler, cv generator, and VCO. The BXR is a nod to vintage Boxcar Averagers, which were designed to acquire and analyze fast signals. The AI250 specifically replicates the real-time mathematical portion of a Boxcar Averager System, and processes audio or cv signals against either another signal or its internal v/o variable wave-shape VCO."

NEVER SEEN THIS BEFORE - An Oscillator Controlled Oscillator // AI Synthesis at Knobcon 2023

video upload by DivKid

"It's always great to see Abe from AI Synthesis, he likes to hide in tomato plants (see below*) but he was out of the garden and into the arms of the wider Chicago area here at Knobcon 2023. Abe had with him an OCO, oscillator controlled oscillator, something I've never seen before and something he believes is unique. It's sort of a VCO expander that creates secondary pulses within the waveform that can be modulation in phase and bipolar amplitude relationship to the input sound. Different input waves gave different wave shapes ... and I really want to try this and get to know more."

AI012 Wave Animator by AI Synthesis | Full Walkthrough, Demo, and Patch Tips

video upload by Robots Are Red

See the announcement post here.

"This video takes a dive into the Wave Animator by AI Synthesis. This is an 8hp pulse harmonic generator. Depending on your input waveform you can get one or two additional pulses between each pulse of the oscillator. You can control the amplitude (positive or negative) of the second pulse, you can control the distance of that secondary pulse from the initial pulse, and you can control both pulses width together. Each modulator also has a cv input with attenuator.

This module is great for more evolving pulse width style effects, triggering flams, clocking swing, and just distorting the heck out of more organic inputs like strings or voice.

Two New Waveshapers - August 2023

video upload by John Schussler

"New month, new modules.

I built the Wave Animator from the kit: it's very straightforward with a small part count and easy assembly.

I most certainly did not build the Foldiplier. It's got lots of parts and does not look to me like an easy project. (Zlob's web page rates its difficulty at 3.5/5)

They're both waveshapers, but with very different approaches. The Wave Animator is based on an Ian Fritz design that produces two pulses whenever it sees an input wave. The Foldiplier is a more "standard" wavefolder/harmonics generator, with the caveat that it has a feedback mode best described as 'pissed off.'

Both are quite fun.

Update: press release follows:

Portland, OR, USA August 17, 2023 – AI Synthesis has released the AI012 Eurorack Wave Animator in both a built and guaranteed version, as well as in kit and PCB/Panel format.
The AI012 Wave Animator is a Waveshaper/VCO Expander that produces two pulses per input wave cycle with voltage controlled pulse width, distance, and amplitude of the second pulse. This design was adapted (with permission and a few changes) from Ian Fritz’s Double Pulse Generator circuit. Some changes were made to the circuit in development.
While the circuit is all analog, the AI012 Eurorack Wave Animator’s pulse wave outputs have a range of timbres from analog wave folding to digital sounding chimes.
The Width of each Pulse is controlled by the AI012 Eurorack Wave Animator’s Width knob and corresponding attenuatable cv input.
The Distance between the second pulse and the first pulse is controlled by the AI012 Eurorack Wave Animator’s Distance knob and corresponding attenuatable cv input. The resulting waveform can have two distinct pulses, or staircase style wave-shapes.
The Amplitude of the second pulse is controlled by the AI012 Eurorack Wave Animator’s Amplitude knob and corresponding attenuatable cv input. It can be negative or positive in voltage value.
In addition to creating new audio rate waveforms, when used as a sequencer, the module can create interesting rythmic variations when the pulses are used as triggers and cv is used to stagger the second trigger.
It comes in both Silver Aluminum versions and Black PCB FR4 versions.

Portland, OR, USA 4/12/2022 – AI Synthesis has released the AI022 Harmonic Mixer in both a built and guaranteed version, as well as in kit and PCB/Panel format.

The AI022 Harmonic CP3 Style Mixer is a discreet mixer using no ICs. As gain increases harmonics and analog warmth are added. As gain increases more, distortion and phasing is added, creating new waveforms from old ones.

The AI022 takes inspiration from the legendary Moog Modular CP3 style mixer, but updates it for eurorack and allows for user customization of the circuit. Many Moog Modular users attribute the CP3 mixer module to providing much of the warmth of the Moog Modular sound.

An exposed Bias knob allows abuse of the circuit, and allows for faithful replication of incoming audio, or radical analog wave shaping and distortion. It is also possible to use the Bias knob to adjust a +/- 5V signal into a 0/+ or 0/- signal.

The AI017 Low Pass Gate Eurorack Module can be used as a Voltage Controlled Filter, Voltage controlled Amplifier, or both. The AI017 is an updated variation of the classic Buchla 200 Series Low Pass Gate, updated with a tunable resonance circuit, and a Depth control. Vactrols are used for control voltage, allowing for classic "ringing" and "bongo" effects.

It can be purchased as a module, or DIY Kit and PCB/Panel Set.

The Depth control compensates the vactrols inability to drop lower than 100 ohms, which can allow audio bleed on traditional Low Pass Gates. The effect can be switched on or off, as depth will attenuate the classic ringing and bongo effect. This gives the user an easy way to go from a "vintage" Low Pass Gate to a "modern" Low Pass Gate with a flick of the switch. A rear trimmer allows for the tuning of the resonance."

"The AI016 Eurorack Tape Echo Interface is a Limited Edition Module that uses a pre-amp and buffered feedback loops to allow a standard three head tape recorder as an analog tape echo. It also provides op-amp saturation on the input when pushed.

The tape recorder must have three heads (erase, record, and play) for it to work as a tape echo. This type of tape recorder will have a button or switch that allows the monitoring of the source audio, or what has just been recorded to the tape. The space between the record and play head creates the delay, and the Tape Interface feeds back into the unit to create repeats.

The AI016 provides the following tape controls:
Mix
Repeats
Input and Output Controls
Delay time is controlled by the tape deck. Not all tape decks allow speed control while recording, and modifications may be needed.
Kits include all parts needed to build and mount the AI011 Eurorack VCO:
Hi Quality Aluminum Panel
