Field recordings of cicadas, Rhodes Mark II, OP-1 field : Imaginary cicada 2025-08-06 by atnr
video upload by atnr
"Field recordings of a cicada-filled park, Nord Lead, and Rhodes
A piece built from park ambience where cicadas sing—heard against the memory of a summer so hot that, these days, even the cicadas in Tokyo seldom call.
This year in Tokyo the heat has been relentless, and opportunities to hear cicadas have become scarce.
Harmony and melodies are performed on the @NordKeyboards Nord Lead and Rhodes.
The field recordings are re-recorded into the @teenageengineering OP-1 field and transformed using its onboard filter and an @KORG_INC NTS-1 for additional processing."
RT custom modular panels
video upload by Ross Totino and Fans of Collision
"Examples of front panel designs I created for my custom 66 space modular system using frontpanelexpress.com CAD software. I was very satisfied with the quality and service from Front Panel Express. The music in the video is from the modular system using the pair of Mini Wave modules for various effects."

Introducing OVUM for Eurorack - Analog Oscillator Bank by Crows Electromusic
video upload by Crows Electromusic
You might remember the stand alone version of OVUM from previous posts here. OVUM has now been ported to eurorack.
Press release follows:



Introducing OVUM for Eurorack - analog oscillator bank
August 6, 2025 - Crows Electromusic, a small synth company fromVancouver, Canada, is thrilled to introduce OVUM for Eurorack, a modular adaptation of our standalone synth OVUM. OVUM for Eurorack is a powerful, all-analog, drone and modulation source designed for exploratory sound synthesis, ambient, drone, and noise music. With five individually controllable and individually routable triangle-core oscillators, OVUM for Eurorack gives you a bank of raw material ready for use in your modular system - as droning dissonance, thick chords, or slow swelling modulation signals.
Features:
• 100% analog circuitry
• Five triangle-core oscillators
• Crossfade between triangle and square waves
• Switch each oscillator to audio-rate or LFO rate
• 4 individual outputs, normalled to 1 main output
• One-control-per-function interface
• 20hp, 3U eurorack standard
• Handmade in Canada
OVUM for Eurorack is our third release, and our first Eurorack module.
It builds on what we’ve learned making standalone products; the palm-sized FM drone box Lore, and the original OVUM. The main challenge of adapting a standalone synth to modular is: how does this fit into a modular context? Five more oscillators is always useful, but with OVUM for Eurorack we’ve built something that can be more than that - an instrument with space available to interact with, either as the voice of your composition, or as the control center for your modulations. We hope OVUM for eurorack will be the place your hands go first when you’re performing a patch.
While it’s designed with ambient, experimental, noise and drone music in mind - we think OVUM for Eurorack is going to be at home in virtually any type of modular system.
OVUM for Eurorack is available now for $150 USD / $200 CAD.
Crows Electromusic is a small synth company based in Vancouver, Canada. Started by Cory Alder in 2023. 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, was released in early 2025.

Tiny Systems Can Have Massively Huge Sounds
video upload by EZBOT
"In today's episode we use a very small eurorack system to create enormous pads, washes, and dub chords to be used in a live set. We will discuss effect routing, module selection, and sampling these sounds into our favorite sampler, the Digitakt II.

STUDIO ELECTRONICS CODE LUXE WAVE FOLDING P1
video upload by ONEPOLYMER
Part 2 here
"Almost out of the box Demo Track including the
ALL NEW STUDIO ELECTRONICS CODE LUXE Synthesizer.
A short WAVE FOLDING Example, live sequenced and recorded. No FX on the CODE LUXE.
The Update/Upgrade sounds amazing - is worth every cent in my opinion (got my hands on since 2hrs).
Every Paramter is now storeable in memory including The 8106 (Roland) Dual Filter Settings as well as the Overdrive and Feedback. The Envelopes sound faster to me ...
Enjoy the bits

New Destiny+ arc*C (16 ideas)
video upload by kirkis
more information www.destiny-plus.com
arc*C is a 4-voice polytonal instrument in which each voice can continuously arc between two independent synthesis engines. fft based Spectral harmonic / phase distortion. Core system attributes include a 32-complex-envelope matrix, ×4 complex 3-D lattice sequencers, ×4 DSP algorithms,127 presets, a partnered drawing app to paint sound with Google Gemini API integration & a 1.91″ AMOLED display.


unique comb filter topologies
phase distortion core:
> 500 harmonics
for FFT stretching, warping, combing and morphing of odd / even partials.
2 large experimental LUTs each with scanning, 4-quadrant multiplication
& phase warping
Envelope matrix, 3-D Lattice Sequencers, DSP, Google Gemini API & arc*C app.
This core is built around 32 complex envelopes and an envelope matrix for all points of control and modulation within the system. These envelopes can have up to 80 break-points and the ability to control segment count, segment looping, rate, amplitude, rate modulation and cycle / trigger source. Randomise envelopes individually or the entire envelope matrix at once.
3-D lattice ×4:
arc*C also has ×4 X-Y-Z lattice Cartesian-like sequencers, represented by four mathematical shapes. Each one steers an invisible point through an 8 × 8 × 8 grid and is constrained by division, jitter, swing, stochastic ratchet/repeat subdivision, axis modulation, snake and orbit shape control, 16-scale index, and per-cell parameters (rest/ratchet %, gate %, probability). These can be the basis of chordal polymetric movements, complex spectral drum rhythms and more.
arc*C has ×4 unique DSP algorithms:
Gorbachev gas 2: 16-pole phaser with through-zero, per-stage coefficient offsets and feedback/resonance.
pnp=f: through-zero flanger.
lorax space 2: Hadamard-matrix reverb / FDN structure.
time cube: experimental 6-min regen delay."
