Introducing... The Swarm, By Artium Instruments

video upload by Artium Instruments

"Artium Instruments is thrilled to introduce its very first offering, The Swarm, a polyphonic desktop synthesizer."

via Artium on Kickstarter

At Artium Instruments, we approach our designs with the understanding that musicians cultivate intimate connections with the gear they employ to create their art. We firmly believe that instruments ought to possess not just functionality, but also personality, character, and a distinct identity that inspires its user. First and foremost, we've dedicated significant effort to ensuring that the synthesizer and onboard effects produce exceptional sound quality akin to professional studio-grade equipment. The Swarm features a SuperSaw oscillator with 8-note polyphony, curated onboard effects, and a full-featured arpeggiator.

At Artium Instruments we are committed to knob-for-knob functionality in our desktop synths. Every feature of The Swarm is directly mapped to a knob, button, switch, or jack, ensuring effortless control. There's no need for menu-diving or complicated button presses to access features; everything is conveniently accessible at your fingertips.

With over a decade of experience in the effects industry, we have carefully curated a selection of effects that complements the synth core. Unique to The Swarm is its capability to use the onboard effects with other equipment, allowing you to route external audio through the input jacks on the back.

We've invested considerable thought into crafting the overall feel of the instrument. From the layout of the knobs to the choice of colors, artwork, and weight of the enclosure, every detail has been considered. These details matter to us because we recognize that the connection a user forms with a piece of gear is nearly as crucial in the creative process as the sounds it produces. We hope you can feel the love and passion we've poured into every detail of The Swarm, from its sonic capabilities to its design aesthetics.

The Swarm is controlled by MIDI through a USB-C port. Most modern class-compliant MIDI controllers with USB functionality should plug in and work immediately with zero setup. Additionally, The Swarm provides power to your controller, streamlining your setup process. For older controllers that only have DIN connections, a USB to DIN converter can be used to ensure compatibility.

The Swarm features a SuperSaw oscillator with 8-note polyphony. This oscillator is composed of seven individual saw waves stacked on top of each other. The magic happens when you detune the waveforms by applying a frequency offset, resulting in one of the most massive synth sounds available.

The Swarm employs this SuperSaw oscillator through two distinct control modes: Polyphonic Mode and Arpeggiator Mode. In Polyphonic Mode, you can play up to eight notes simultaneously. Arpeggiator Mode offers a comprehensive monophonic arpeggiator, automatically sequencing held notes in a variety of patterns.

All onboard effects can be used with external equipment. Simply plug an external audio source into the rear input jacks, and The Swarm will seamlessly mix the external audio with its synth core, allowing for simultaneous processing of both signals.

By pressing the touchpad on the right, The Swarm records a 1000ms sample of the current audio. It then layers, and smears the sample, creating an infinite drone frozen in time—a perfect foundation for layering additional notes. The freeze effect facilitates overdubbing, and pressing the touchpad with the freeze knob at its minimum setting erases the memory, allowing you to capture a fresh sample.

The Swarm's delay is a digital delay with a subtle touch of warmth. The delay length synchronizes with the arpeggiator clock, which can be adjusted manually using the clock knob or via the tap tempo touchpad on the left. Additionally, the delay features a multiplier knob, offering a range of unique subdivisions that complement the synced arpeggiator, including quarter notes, dotted eighth notes, eighth notes, and triplets.

The reverb effect in The Swarm strives to enhance the natural body and ambience of the synth core without overshadowing it. Its stereo reverb algorithm is controlled by a single knob, which adjusts both the mix and decay simultaneously. This versatile control allows you to seamlessly transition from realistic room or hall effects to expansive cathedral-like soundscapes, offering a wide range of atmospheric possibilities.

The SuperSaw oscillator practically demands to be paired with a chorus effect. The Swarm employs a stereo 4-voice chorus effect alongside a gradually shifting LFO, aiming to craft dimensionality without becoming nauseating.

FLUORINE - GENERATIVE RECURSIVE BYTEBEATS - Preview

video upload by SPHERICAL SOUND SOCIETY

FLUORINE UNEDITED PERCUSSIVE JAM DEMO




"Fluorine is portable synthesizer that is powered via USB C type cable and therefore can be powered via a Power Bank. It´s a high definition modern take on a classic 8 bit synthesis called Bytebeat and discovered in 2011 by the encomiable Viznut but brought to the future with a lot of new features.

It runs it in various selectable Bitdepths, not just the classic 8 bits. The higher the Bitdepth, the softer, rounder and higher definition the sound becomes it.

Fluorine also features 2 new ways to calculate the the classic mono Bytebeat synthesis in native stereo that sounds rich, wide and tridimensional.

The sound engine currently has 2 modes. LIQUID and SOLID. It affetcs the character of the output.

Another bit that it adds to the classic bytebeat synthesis is the addition of modular and stackable algorithms that process the mathematics under the hood and a recursive Mode that cycles between this algorithms and that turns it all into a new whole synthesis technique, now called "Recursive HD Bytebeats", that altogeher with the stereo modes and Bitdepth features turns this machine, the Fluorine, in probably most advanced way to explore Bytebeat synthesis as in november of 2023.

Fluorine comes in 3 flavors:

-As a fully assembled unit

-As a full kit that the user has to build

-As a PCB + Programmed microcontroller for advanced builders. The user has to source the rest of the components and build the synth.

There´s a user guide that explains every function, knob and button that you can download here.

Mapper: map01/12/21 Chaotic Synthesizer Prototype Demonstration

video upload by Ryan Gaston

"A demonstration of map01/12/21, an electronic musical instrument that focuses on random, chaotic, and gestural interconnections between its constituent structures. map01/12/21 has been succeeded by map02/21, which offers nearly identical functionality; this video serves as an archival demonstration of the older prototype.

map01/12/21 combines three modules: the map01 Delta Scan Mapping Interface (a chaotic audio generator), the map12 Windowed Temporal Drag Processor (a dynamically re-writable audio buffer), and map21 Multiple Vector Source + Translation Matrix (a MIDI controller that combines two joysticks, sixteen random number generators, a timing generator, and a data routing matrix). map01 and map12 have been abandoned in favor of the newer map02 Delta Scan Mapping Interface + Windowed Temporal Drag Processor, which combines their functionality into a single device.

This improvisational demonstration highlights many of the unique possibilities of each of its constituent parts; ranging from blasts of noise to whistling tones, stuttered repeats, aliasing, goofy computer-generated bleeps, and gesturally-controlled chaos."

Continual Transition - a Memory Machine [Sound/Noise Demonstration]

video upload by Ryan Gaston

"Continual Transition is an electronic sound-making device designed to engage memory, inspired by the unique otherworldly dread of isolation in the Ozarks.

Continual Transition uses a simple synthesis structure, modulated delay lines, sampling, and multiple internal feedback/feedforward nodes to create a chaotic, constantly evolving musical structure. Despite its use of relatively simple synthesis "building blocks," its embrace of chaos and its perhaps-peculiar parameterization makes it such that individual controls often results in individual knobs affecting many aspects of a sound's character, usually in nonlinear or unpredictable ways.

Continual Transition is comprised of two primary sections: on the left, a Temporal Reflection Interval Processor (TRIP), and on the right, an Arbitrarily Traversal Memory Register (ATMR). The TRIP and ATMR are intertwined via multiple intermodulation nodes, allowing them to influence one another's behavior in a number of ways. The TRIP is a continually-degrading memory process, in which user actions are echoed, multiplied, and obfuscated continually as time progresses. The ATMR is a sampling device, which assesses the device's total state for concentrated periods of time, locking small windows of "memory" into a buffer which can be bent, twisted, folded, and traversed linearly or chaotically.

By allowing these two forms of memory to commingle—and by gradually learning the relationship between individual controls, the immediate sound, and the way that sounds progress into the future—the user may develop a peculiar sense of "presentness," in which the events of the past and immediate future gain greater clarity and present actions take on greater-than-typical weight.

Continual Transition was created with a Bela Mini, Pure Data, simple custom circuitry, and Arkansan cedar sourced directly from the forests of the Ozarks. A limited number of Continual Transition devices were created in 2020. Despite initial goals to the contrary, there is no current plan to develop it into a commercial product.

If you want to learn more about Continual Transition (and to hear more examples of how it can sound), see the Summer 2019 edition of SciARC's Offramp online magazine here: https://offramp.sciarc.edu/articles/c..."

Stereo Transfer Function Synthesizer - Proof of Concept (Teensy)

video upload by Ryan Gaston

"A simple demonstration of some of the sounds yielded from a simple Teensy-based synthesizer. This is a proof of concept more than anything else; ultimately, this will be integrated into a more complete instrument.

The internal signal path is based on a combination of phase modulation, frequency modulation, and digital waveshaping via arbitrarily constructed transfer functions. Three oscillators intertwine in various ways, each contributing to the sound's instantaneous timbre, pitch, loudness, and sense of spatial location. The use of many internal feedback/feedforward nodes enhances the potential for chaotic, unpredictable sonic structures.

Originally, the idea was to create a stereo oscillator with transfer function-based waveshaping; however, I found that with a sufficiently knotted internal signal flow, it was possible to achieve a pretty astonishing range of animated sounds using relatively limited means. Though very much inspired by the Hordijk Blippoo Box, Hordijk Benjolin, Serge Wave Multipliers, Buchla Touché, Buchla 400, Buchla 700, and Buchla 259e, and some experimental works by Larry Polansky, I'm finding that there's much more sonic territory to be explored utilizing the bizarre combination of feedback and waveshaping via arbitrary transfer functions.

Again, I hope to continue to expand this into a more complete, performable instrument. But for now, enjoy some noise."

PhonicBloom GechoLogic Loopstyler

video upload by Gecho Loopsynth

"After a lot of prototyping, we're finally happy with the circuit, and here are its first sounds! :) We've opened preorders at https://phonicbloom.com/ [priced at €175 +VAT] and manufacturing will commence shortly, our favourite PCB factory is happy with the blueprints and all components are in stock. If you are interested in technical details and the development journey, check https://loopstyler.com/.

This demo shows a very basic configuration: 4 samples across 4 rows of pads, sharing the same octave and mode. After activating the arpeggiator, you can change key, octave, mode, or instrument that the arpeggiator controls. We also hear complaints about incorrectly entered command sequence; this prototype lacks texts on some pads, and LED lights are not yet showing cues about what is going on, which makes it harder to control. An annotated video explaining these controls in detail, will be recorded once the first production unit arrives from the factory."



"The Loopstyler is a powerful pocket synthesizer capable of running multiple sound engines and effects at once. It can handle a large amount of samples on the SD card, limited only by the card capacity. Browse and organize them easily to be used in patches, play them back with at least 32‑voices polyphony, smooth time stretching and pitch shifting.

You can play the Loopstyler in different ways: like the classic Stylophone, or in a tape loop emulation mode, or by programming it using the multitrack sequencer. Apart from the sampled sounds, it runs other sound engines, such as FM, Karplus‑Strong, granular and subtractive synthesis. The usual suite of effects can be applied per voice or globally. A single microphone and monophonic line input allow for sampling possibilities (you can import stereo samples easily via the SD card).

Designed to fit snugly in your pocket, Loopstyler is the source of endless hours of fun anywhere you go. And of course, everything you play can be recorded internally, so nothing is lost."
