Vekte Public Beta Now Open
You might remember Vekte from this previous post. The public beta for it is now open. Details follow:
"Vekte is a generative MIDI sequencer plugin. It runs 31 algorithms — Euclidean, Markov, cellular automata, Xenakis sieves, Kaprekar, logistic maps, and more — and uses them to write patterns to drive your instruments.
Every channel has one note lane and four modulation lanes. Each lane runs its own algorithm and can target velocity, length, any CC, transpose, scale, chord, octave, or another lane's parameters, with sixteen slots per session (which can be either routed freely to any channel, including multiple slots controlling one single channel).
The engine is deterministic. Each pattern is hashed from its algorithm and parameters into a seed, so a given configuration always produces the same result. Patterns are exact and repeatable, and you can export any state as a preset string to recall later or hand to someone else (this part is still WIP, and will be improved massively in the next one).
It began as the software side of Rekke, our hardware sequencer, and the two share part of the same algorithmic core.
This is a public beta. VST3 only for now, on Windows and macOS. AU and an iOS AUv3 build are planned, but I want VST3 solid first. Free during the beta.
I'm after real feedback: what breaks, which hosts misbehave, what's confusing, what's missing. Bug reports and DAW-specific quirks are the most useful thing you can send (you have a form in the menu for direct feedback from the app).

Moog Muse: 64 Vintage Arp Presets. Sound Demo. Live Jam
video upload by Anton Anru
๐ผ 'Cassette Motion' is a collection of 64 arpeggio presets for Moog Muse.
The collection embraces a retro character—highlighting detuning, subtle noise, and analog warmth to evoke the sonic aesthetics of the 70s and 80s.
The patches are infused with nostalgic charm and are perfect for adding that vintage soul to your tracks.
๐ฆ The download link: https://antonanru.sellfy.store/p/muse...
๐ป The timbral range is wide and diverse, covering dark, noisy, lo-fi, warm, deep, soft, retro/vintage, melancholic, atmospheric, detuned, FM, distorted, metallic, evolving, and sweeping.
๐ All patches are Velocity-sensitive. The ModWheel enhances expressiveness by adding motion and tonal variation—brightening the sound, introducing vibrato, shifting timbre, or adding extra movement for dynamic and engaging performance.
Aftertouch introduces distortion, detune, or resonance.
The Macro Knob introduces additional changes—it adds bright overtones, or adds modulation to the filter or oscillators.
๐งฟ These presets are versatile and can be used in any genre of electronic music, such as techno, ambient, IDM, industrial, drum and bass, and others. This collection is also an invaluable resource for soundtrack composers, game developers, audiobook producers, video creators, advertisers, and social media content creators.

Polivoks Synthesizer | Vladimir Kuzmin Tribute
video upload by RetroSound
"Vladimir Kuzmin, the creator and designer of the legendary Polivoks synthesizer, passed away last week.✨
I had the privilege of communicating with Vladimir several times, and I always experienced him as a very kind, helpful, and incredibly humble person. Behind one of the most unique synthesizers ever created was not only a talented engineer, but also a warm and generous human being.
This video is dedicated to Vladimir.
For this tribute, I created a cover version of “Summer” (“ะะตัะพ”) by Kino, a Russian band whose music I deeply appreciate. The entire arrangement was made using only the Polivoks synthesizer — every sound, melody, texture, and atmosphere comes from this unique instrument.
The Polivoks was developed in the Soviet Union in the early 1980s and became famous for its aggressive character, distinctive multimode filter, and raw analog sound. Originally designed as a compact alternative to Western synthesizers, it later became a cult instrument among musicians and synthesizer enthusiasts around the world.
Thank you, Vladimir, for creating an instrument with such a powerful voice and for leaving a lasting mark on electronic music history.
Rest in peace.✨"

video uploads by Jonas Eriksson
"Annulus is a six-mode resonator instrument for the modern music producer who treats sound like material. Modal, FM, string, and sympathetic voices feed directly into tape delay, shimmer reverb, and analog drive — a full sounddesign chain in one plugin, shaped by four expressive macros. At home in any musictech setup: fast to sketch a melody, deep enough to lose hours in texture.

The engine
Annulus routes your signal through four linked processors:
Rings: a MIDI-driven polyphonic resonator based on Mutable Instruments' Rings, running six distinct physical modeling algorithms. Eight voices spread across the stereo field with velocity and position randomization for organic variation on every hit.
Spiral: a stereo tape delay with tempo sync, ping-pong routing, wobble modulation, and saturated feedback.
Velvet: an algorithmic reverb with shimmer, diffusion, ducking, and a four-second tail.
Distortion: twelve waveshaping models at 2× oversampling, from soft tube warmth to asymmetric fuzz.
Four macro knobs: Morphe, Aigle, Nothros, Topos. Reach across the entire chain simultaneously. One gesture shapes the resonator, the delay, the reverb, and the drive at once. Topos also integrates into the visualizer's rotation, tying the image to the physics of the sound."

"We say...
A pre-owned Bastl Instruments Kastle ARP in excellent condition. It comes with original packaging and accessories.
Manufacturer's description
Kastle ARP is a unique modular melody generator based on a quantized sine wave oscillator with a digital waveshaper.
The pitch selection employs straightforward concepts to unleash surprising intricacy. The quantized oscillator ensures it is always in tune, and its pitch can be selected using the NOTE and CHORD inputs. The decay envelope adds variation by occasionally skipping pitches before retriggering. The timbre control allows you to blend between noble sine waves and 8-bit chip-tunes.
