GreyScale-NewTune #kosmos2

video upload by plantssystem

"GreyScale returns with a new generative performance built on the evolving KOSMOS‑2 engine, this time in collaboration with the PS‑Vita–based Drum Stream DS‑8.

The pairing creates a bright, solid sonic architecture: KOSMOS‑2 drives fluid melodic motion and probability‑based phrasing, while the DS‑8 injects crisp digital percussion with a uniquely handheld character.

The result is a compact but highly dynamic system — a hybrid of embedded generative logic and portable drum synthesis — forming a sound that is unmistakably GreyScale: minimal, sharp, and constantly evolving.

Features highlighted in this release:
- Generative Engine — KOSMOS‑2’s expanded modulation paths and refined Euclidean behavior
- Hybrid Clocking — pulse‑driven interaction between sequencer and handheld drum module
- Bright Solid Timbre — DS‑8’s digital transients layered with KOSMOS‑2’s controlled harmonic drift
- Portable Performance Setup — a minimal rig producing a surprisingly wide sonic field

A fresh direction for GreyScale, and a glimpse into how compact devices can form a powerful generative ecosystem."

"KOSMOS2 & KOSMOS‑ONE — Generative Synth Engines by plantssystemplantssystem introduces two new generative sound engines — KOSMOS2 and KOSMOS‑ONE — both built on the PRA32‑U2/M architecture and designed for compact hardware instruments.

They share the same musical DNA but serve different creative roles:

KOSMOS2 is a 4‑part autonomous generative system, while KOSMOS‑ONE is a minimal, single‑part generative engine optimized for small builds and embedded devices.KOSMOS2 — Four‑Part Generative EcosystemKOSMOS2 is a multi‑layer generative engine running on Raspberry Pi Pico2 or RP2040 hardware. It features four independent musical agents — Melody, Bass, Chord, and Sequence — each following its own rules while interacting within a shared harmonic framework.Key features:4 autonomous generative parts with deterministic behaviorPRA32‑U2/M synth engine running on Core1 with stable 44.1kHz I2S outputReal‑time control via TouchOSC or external MIDI CCScale, chord, arpeggio, and pattern generation with per‑part randomizationOptimized for RP2350 with improved DSP headroomDesigned for live performance and installation useKOSMOS2 makes its public debut at Hamamatsu Micro Maker Faire 2026, exhibited at the ISGK Instruments booth.

KOSMOS‑ONE — Minimal Generative Engine for Small HardwareKOSMOS‑ONE is a compact, single‑part version of the KOSMOS engine.

It is designed for ultra‑small hardware builds, micro‑instruments, and installations where simplicity and stability matter more than multi‑part complexity.Key features:Single‑part generative engine based on the KOSMOS2 architectureExtremely lightweight DSP load suitable for tiny microcontroller buildsDeterministic melodic generation with scale and mode awarenessIdeal for standalone sound objects, embedded synths, and minimal interfacesKOSMOS‑ONE preserves the musical character of KOSMOS2 while reducing the system to its most essential generative core.

TogetherKOSMOS2 and KOSMOS‑ONE form a modular family of generative engines — from full multi‑part generative performance to tiny embedded musical objects — all powered by the PRA32‑U2/M synthesis architecture."

Introducing KOSMOS-ONE by GreyScale

"Introducing KOSMOS-ONE.

Despite being an extremely small piece of hardware—just a thumb-sized Raspberry Pi Pico + DAC—all parameters can be fully controlled via TouchOSC.

A new minimal generative instrument that lets you enjoy the sound creation of the PRA32-U 'in the palm of your hand.' It's small enough to sit on the edge of your desk, yet it can create 'that sound' just fine."

GreyScale-GeneratePulse #kosmos #renoise

video upload by plantssystem

"GreyScale has released their latest project, 'GeneratePulse,' which fuses intricate rhythmic structure with an intense visual experience.
The core sound production of this work utilizes Renoise, a leading tracker-type DAW. Fully leveraging Renoise's unique step-based precision sequencing capabilities, a tight, glitchy beat is constructed, themed around "Pulse," as the name suggests. Tracker enthusiasts will undoubtedly appreciate the meticulous programming that conveys a sense of vertical energy.

For visual effects, the hardware video visualizer QuantumVJhd is employed. It converts audio signals into glitchy video in real time, creating luminous visuals perfectly synchronized with the sound pulses.

A fusion of sharp pulsed beats and abstract, high-brightness visuals that respond to the dynamics of the sound.

This work, where the mathematical beauty of digital trackers intersects with analog-like glitch visuals, can be considered a pinnacle of contemporary audiovisual works."

🎛️ GreyScale — Generative Instrument Playlist / Phase4

video uploads by plantssystem

GreyScale presents “Phase4,” a curated playlist documenting the evolution of Generative Instruments.
This edition focuses on KOSMOS, a self‑contained generative instrument built on the Raspberry Pi Pico (RP2040).
Through a series of short videos, Phase4 traces how the instrument’s behavior, algorithms, UI, and sound design have taken shape over time.

Within the tight constraints of the RP2040, the playlist explores how phrase generation, timing variation, and timbral movement are implemented, and how a minimal hardware platform can still produce expressive, autonomous musical motion.
Phase4 serves as a compact archive of experiments, breakthroughs, and the small decisions that allow a machine to “begin to sing” on its own.

For those interested in DIY instruments, generative music, embedded sound design, or the aesthetics of algorithmic motion, this playlist captures the current state of GreyScale’s generative instrument research.
