KOSMOS – Ultra‑Stable MIDI Sync Mode

KOSMOS features a custom timing architecture that delivers an extremely stable, ultra‑low‑jitter MIDI Clock (24ppqn).
Whether you use DAWs, hardware sequencers, drum machines, or modular gear, KOSMOS provides a rock‑solid master tempo designed for professional, performance‑ready synchronization.

KOSMOS – A Generative MIDI Sequencer for RP2040 (DIY Project)

You might recall KOSMOS from previous posts here. Plantssystem aka GreyScale wrote in to let us know the source code has been released. Details and link to the github repository follow.

"KOSMOS is a compact, self‑contained generative MIDI sequencer built on the Raspberry Pi Pico (RP2040).

Power it on, and it immediately begins producing evolving melodic patterns — no DAW, no clock source, no setup.

The project combines a Euclidean rhythm engine, Japanese‑mode melodic generation (Hirajoshi / Insen / Miyakobushi),
and a 240×240 LCD UI for real‑time visualization of steps, probabilities, and phrase movement.

A small instrument with a surprisingly expressive voice.

"KOSMOS – A Compact Generative Sequencer Driving the Prophet‑5

This short clip features KOSMOS, my standalone generative MIDI sequencer, controlling a Sequential Prophet‑5. KOSMOS creates evolving melodic patterns and rhythmic variations in real time, while the Prophet‑5 provides its unmistakable analog warmth and depth.

The performance is completely autonomous — no DAW, no external processing — just KOSMOS generating the sequence and the Prophet‑5 responding with its classic tone.
It’s a small glimpse into how KOSMOS interacts with hardware synths and how expressive the pairing can be."

GreyScale - Phase3

video uploads by plantssystem

"GreyScale 'Phase3'
Centered around the Duos, the Poly-Sequencer receives its pulse, and sound rises up as a single structure. This series records the "acoustic architecture" created not merely by synchronization, but by moving with the same heartbeat. Minimal pulses shape the space,
and as the CS-10, Prophet-5, and Duos layer upon each other, you can follow the process of how GreyScale's unique three-dimensional sound develops.
This playlist is an archive of GreyScale's exploration of 'pulses create the world.'

🎛️ 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.


🎛️ GreyScale が届けるドキュメント・シリーズ「Phase4」。
Raspberry Pi Pico を中心とした Generative Instrument（生成楽器） の開発記録をまとめています。
メインとなるKOSMOS の動作ログ、アルゴリズムの変遷、UI・音響処理の改善など、“楽器が自律的に歌い始めるまで” のプロセスをショート動画で追える構成になっています。

RP2040 の限られたリソースの中で、どのようにフレーズ生成・タイミング揺らぎ・音色変化が実装されていくのか。
ハードウェア単体で成立するミニマルな生成楽器の思想と、その裏側にある試行錯誤をコンパクトにアーカイブしました。

DIY シンセ、ジェネレーティブ音楽、独自アルゴリズムによる“動きのある音”に興味がある方に向けた Phase4 です。

GreyScale – A Standalone MIDI Sequencer KOSMOS Powered by Raspberry Pi Pico (RP2040)

This one is in via GreyScale aka plantssystem whose videos you have likely seen on the site.

"GreyScale is a compact, self‑contained MIDI sequencer built entirely around the Raspberry Pi Pico (RP2040).

Its minimal hardware footprint hides a surprisingly deep generative engine, combining Euclidean rhythm generation, step sequencing, probability control, and evolving melodic behavior.

The clean GreyScale UI provides immediate visual feedback — step activity, Euclid parameters, probability states — all rendered on a crisp LCD. A joystick and four dedicated buttons offer fast, tactile control, keeping the workflow musical and instrument‑like rather than menu‑driven.

GreyScale runs completely standalone with standard MIDI output, making it an ideal partner for hardware synths, desktop modules, or DAW setups.

Designed for spontaneity and long‑form generative performance, it encourages exploration and rewards experimentation. A small instrument with a refined feel, GreyScale blends DIY charm with a polished, modern sequencing experience."
