Theremon+ [First Look]

video upload by MoShang

"The Theremon+ is the successor to the kit-built Theremon by Groovesizer. While the original was limited to a single voice, the Theremon+ adds a second wavetable-based voice with an arpeggiator, and a drum section with various styles and 4 kits. The original was intended exclusively for the DIY market, but the plan is to sell the Theremon+ fully built. We hope to offer the Theremon+ at the same price point as the original (around US$130) - would you back it on Kickstarter? https://groovesizer.com"

Introducing Lore - FM oscillator pair by Crows Electromusic

Press release via Crows Electromusic:


March 26, 2025 - Crows Electromusic, a small synth company from Vancouver, Canada, is thrilled to introduce Lore, a standalone all-analog tool for exploratory sound synthesis, ambient, drone, and noise music. With individual controls for each function, Lore gives direct control of two independent triangle-core oscillators and can be switched to an FM synthesis mode to unlock a wide range of complex tones. The instrument’s unique un-quantized interface is perfect for exploring pure tones, drones, and FM sound textures.

Features:

• 100% analog circuitry
• Two triangle-core oscillators
• Crossfade between triangle and square waves
• One-control-per-function interface
• Fully standalone, just add headphones
• Transparent bioplastic enclosure
• USB powered
• Handmade in Canada

Lore is our second release, building on what we’ve learned making our first product OVUM analog sound explorer. We had two goals in mind during development: first we wanted to make something that could create a harsher and more aggressive sound, and second, we wanted to see how small a synth we could make. On both fronts we think Lore is a success - it measures under 3 x 3 inches, and the FM mode gives you access to a whole range of shimmering, grinding, and metallic sounds. Just like with OVUM, we prioritized immediate control and ease of exploration. No understanding of oscillators, wave shapes, or FM synthesis is required to pick it up and start creating interesting and inspiring sound. We think people of all ages, musical abilities, and experience levels are going to love this instrument.

Lore is available now for $79 CAD / $59 USD.

Crows Electromusic is a small synth company based in Vancouver, Canada. Started by Cory Alder in 2022. Crows’ goal is to develop new hardware instruments that challenge the established ways we interact with sound and music creation. Their first product, OVUM was released in 2023, and their second product Lore is available now.

"Sound effect - sound modulator. A. Chervonsky.
In the video, first the sound from the electric guitar, from 2:45 with the voice, and from 4:12 from the audio player, the voice and the song.
Description from the magazine: "the described device makes it possible to modulate the amplitude and phase of the EMI signal with the audio frequency voltage from the auxiliary generator. The sharp specificity of the resulting musical effect (there is no established name for it) significantly limits its use, but in a number of cases of pop practice it can be quite justified. The frequency of the auxiliary generator can be changed during the game, introducing new colors into the sound of the instrument. In addition, the device has a vibrato generator, which additionally modulates the amplitude of the generator signal, which, in turn, leads to a timbre vibrato of the sound at the EMI output. The device has been tested in operation together with an electric guitar, but it is possible that good results can be obtained with other EMI."
magazine "Radio" No. 4 . 1980. Page 57.
https://archive.radio.ru/web/1980/04/...
--------------------------------------------
(my addition - added a microphone amplifier to the circuit (it also came in handy for amplifying the guitar). The low-frequency generator (vibrato) is of course already outdated and has a small range. I increased the value of resistor R25 by 47-50 kilo-ohms, otherwise vibrato would not work. And I decided to add a variable resistor of 1 mega-ohm, after R12, to adjust the intensity of the effect. Although this does not give much)."

Hexaphonic Witchcraft Synth by Ekkoflok Electronik

The Hexaphonic:
Six fully tunable oscillators
Touch controlled
Stereo panning
Amplitude
100% weird starve control for chaotic sounds



via Ekkoflok Electronik

"Introducing the Hexaphonic

A synthesizer, a choir of six oscillators joyfully singing along or against each other, producing an output spanning from harmony to cacophony, all by the touch of your skin.

'Hex' is the greek word for "six" and close to the Danish word "heks", which means "witch". It is about time we throw some witchcraft in our electronics and honour the wise women of the past and the present.

Electronic engineering is in many ways rather conservative, but fortunately there are cracks in the surface - like sticking your fingers inside a circuit or "starving" a circuit to intentionally prevent it from operating predictably. HEX is such a circuit - you play it by extending the circuit with your fingertips (or other conductive matter), and force it into chaos by cranking the "starve-control". Let the circuits starve and spare the abundance for the Humans in need.

Like human beings HEX is a mood swinger of sorts; it's mood changes rapidly from harmony to chaos - blindly obeying the orders of the starve control. If the electrodes are the limbs of HEX, the starve-control is the brain - or maybe rather a parasite of sorts, taking control of an otherwise well-behaving instrument. Luckily it seems that HEX is perfectly happy with returning back to a normal state again after a trip into chaotic territory; thereby reducing the starve-control to a humble way of controlling the timbre - it's not a filter, nor a wave-folder, but it surely does alter the timbre in a non-linear and most importantly pleasing manner.

Starving circuits is not a new thing; it has been exploited in fields of circuit bending for ages, and interestingly it is also a well-known trick among guitarists to emulate the sound of a fuzz pedal with a dying battery - by limiting the current flowing from the battery. However it is not something you see on the front panel on the average Behringer synthesizer (yet?!).

Please note that 'PCB only' means that you are buying a bare circuit board and have to source the components for yourself."

"Introducing the Oscitrode
A synthesizer controlled by your skin and breath.
You extend the circuit by letting the current flow through you and the circuit extends you by turning the physical contact into sounds yielding from simple oscillations to complex and chaotic patterns.

Six analog oscillators controlled by and interacted with through twelve electrodes.
A "starve" control known from the world of circuit bending serves the mean of varying timbre and modulation in a nonlinear and chaotic way.

The electrodes are made of bare non-tinned copper and will probably change colour (and conductivity) over time adding a final time dependant layer of complexity to the circuit."

"Polyphonic drones, light-controlled warping, rhythmic looping - My newest one-off functional art piece, the 'Space Collider.' Built in a vintage snap-on battery testing shell that was modified and flipped upside down. This instrument features a four-channel drone feeding an old circuit bent delay. This resulted in the gnarliest drone machine to date when combined with a joystick-controlled delay to create oscillation squeals, glitch effects, and even looping.

I included a demo from Emily Hopkins. This is for a previous drone machine I made. This one uses the same circuit - going into a delay! So it is a bit more advanced than the one Emily used.

Short demo can be found on my IG page, addpedals. I am also open to trades for guitars if you are local."

This Sonic Chessboard is a passive Optical Octophonic Audio Panner / light sensitive "chessboard", based on the design by Lowell Cross for John Cage's and Marcel Duchamps' musical chess performance Reunion (1968). It routes 16 audio signals via the 64 light dependent resistors to 8 separate audio outputs. Cover the squares on the board with chess pieces or your hands to make sounds roll through a room and add to the spatial distribution of all the different inputs. Best to be played with a strong bright light mounted on the ceiling above the chessboard.

Limited edition DIY Kit, available at: https://sonicartefacts.com/product/so... & https://patch-point.com/collections/s...

The materials were originally made in small series for Wouter Jaspers' installative sound performance "Indeterminate Structures (2023). Big thanks to ‪@Hainbach‬ for playing chess with me and ‪@Sonoscopia‬ for the original sound installation and of course to the great folks of ‪@patchpoint4043‬ for hosting us!"

Press release follows:

Berlin, Germany – Sonic Artefacts is excited to announce the release of the Sonic Chessboard, a unique DIY musical instrument that merges the worlds of chess and sound. Inspired by Lowell Cross’ design for John Cage’s Reunion (1968), the Sonic Chessboard offers a captivating way to create spatial sound experiences.

The Sonic Chessboard is a passive Optical Octophonic Audio Panner that routes 16 audio signals via 64 light-dependent resistors embedded in the squares to 8 separate audio outputs, changing the volume when a chess piece gets moved from one square to another. By strategically placing chess pieces on the board, users can control the volume and flow of sound, creating dynamic and immersive soundscapes.
