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."

The SOUL of the KORG Z1 - Ethereal Textures & STRYMON BigSky / No Talking


video upload by Matzumi

"Experience the breathing soul of the Korg Z1.
In this studio session, the Korg Z1 meets the Strymon BigSky – a combination of pure magic. Together, they open up mystical soundscapes that are as inspiring as they are profound.
The result is a sound that is both dystopian and beautiful, possessing a unique radiance.

It’s a sound that seems to breathe on its own. Join me and get lost in resonance.

I’ve spent some time getting lost in the resonance of the Korg Z1 paired with the Strymon BigSky.
-------------------------------------------------------------------
Music is emotion, music is language - the oldest in the world.
Music is so much more than just the sound in the ear.

Techno Live Jam - 140 | Tonverk meets Perkons HD-01


video upload by Mark Cee

"What heck, was feeling 140 today and thought about running Perkons main out into one input on Tonverk and the main send out into the other Tonverk input. Tonverk provides the FX Chain. Now I just move the sends on each Voice on Perkons. The vast amount of routing options and FX in Tonverk make it a pedal killer as well. It does a lot. Massive utility.

Perk still my favorite off all time."

Yuyo cmos synth - First try Attiny85 dco with analog cmos shaping and twin t filter


video upload by JIANT

"everything is from the synth to the zoom recorder, twin t drums, xor snare, pt2399, and cmos stuff.

attiny85 reseting the phase of 40106 oscilators, the digital control accepts 1voct from keysetp and go to the 40106 inputs through resistors, a little rc for filtering the pwm, and for this reason when you change the oscillator frequency you can get intervals and crazy stuff. is not orthodox but suits my need for Rich timbres. the dco goes to 40106 buffers , and then 4040 dividers, twin t filters, one for each of the two voices, one goes to env, vca, filter, delay, and the other one to clock divider and filter, to get the sub osc.

firmware super simple only for checking the conversion from filtered frecuency of the attiny85 to my 40106 non exponencial vcos.
currently is tracking 10 octaves really good, the trick is put a voltage divider in the cv in of the attiny because keystep has 0 to 10v and the attiny accepts 0 to 5v tehn the tracking inside the attiny converts o.5v oct to 1 volt oct. i dont know anything about coding but i made it with chat gpt and my design . source code will be in the coments ."

Introducing Entanglement - Quantum Wavefunction Synth (VST3/AU/Standalone)

5. First experiments with "Entanglement" dual polyphonic wavetable synthesizer - Richard Divine
6. Entanglement Synthesizer by Dillon Bastan (No Talking) - Elektronick Musick



"Entanglement uses a 1D quantum wave function (Schrödinger equation) to produce evolving waveforms for use in a dual polyphonic wavetable synthesizer. You can add energy to the simulation in various different ways (wave packets/quantum particles, free draw, and waveform files) and those waveforms will evolve and transform based on the equation and your settings. You can also add environmental factors (potentials) to transform the energy/waveforms in different ways. Additionally you are able to manipulate the resulting waveform in different ways (stretching, warping, quantizing, smoothing, FM etc). You can derive your waveform from the wave function with many different equations and value options each of which offers a different sound. Each oscillator has its own independent wave function, energies, potentials and settings. Both oscillators can also be entangled adding a rich and complex modulation of the waveforms. That coupled with an internal modulation system makes this device a powerhouse for insane sound design! From basic synth sounds, to complex evolving sounds, to crazy mind blowing sounds. The evolving nature and very compelling transformations of the waveforms through the quantum wave function stands this synth apart from the many other wavetable synthesizers out there.

Owners of the M4L version of Entanglement get a discounted price (use the same email at purchase)!"

Waldorf Attack 3: A Classic Reborn! (No Talking Demo)

video upload by Limbic Bits

"In this video, we’re diving into the Waldorf Attack 3 Plugin — Version 3 of that classic Drum Synthesizer PlugIn!"


Attack is back.
And it’s more powerful than ever.
We are proud to unveil Attack 3, the next evolution of one of Waldorf Music’s most iconic and longest-running instruments. A true classic reborn, Attack 3 redefines what a modern percussion synthesizer can be.

At its heart lies a mighty analogue-style synthesis engine, delivering 24 individual sounds per kit, with 12 sounds playable polyphonically as pitched instruments. From punchy kicks to melodic percussion, Attack 3 is built for rhythm that moves both bodies and speakers.

Attack 3 captures the unmistakable spirit of legendary 1980s analogue drum machines and the driving electronic club sound of the 1990s — and propels it boldly into today’s productions. It’s a future-ready instrument designed to shape the drum sounds of the next decade.

Every sound is alive
Every parameter can be tweaked in real time and fully automated in your DAW, inviting hands-on exploration and deep expression. While sampling capabilities have been expanded, Attack stays true to its philosophy: pure synthesis first, allowing you to create unique percussion sounds from scratch.

Redesigned for Faster Drum Creation
With a completely redesigned, scalable interface and a vastly expanded synthesis engine, Attack 3 proves that after more than 25 years, it remains the go-to tool for producers who want total control over their drums.

The new user interface adapts effortlessly to any screen size, while enhanced MIDI Learn lets you define minimum and maximum parameter ranges for expressive performance. Dedicated browsers for kits, sounds, samples, and MIDI mappings keep inspiration flowing without interruption.

Advanced Sample Playback
The oscillator section has been refined for absolute precision, featuring accurate phase control for synthetic waveformsand powerful sample playback options, including user samples, velocity mapping, round-robin playback, and flexible start positions. Whether you want surgical accuracy or organic variation, Attack 3 delivers.

Building music. Cable by cable. | Ģirts Ozoliņš | TEDxRiga


video upload by TEDx Talks

Spotted this one searching the TEDx Talks channel for the recently taken down Sounds of Tomorrow video. I'm not finding this one with Ģirts of Erica Synths on the site, so up it goes. Note it's from 2019 and an interesting look back on the time.

Video description:
"Instruments can open a world of opportunity for creative expression. And when that instrument is a synthesizer, that opportunity becomes nearly limitless. What does it take to open the floodgates of creative exploration? In the mind of Girts Ozolins, it takes making musical instruments more accessible to the masses. Girts' interest in electronics, electronic music and synthesizers developed when he was only twelve years old. Now he is a founder of Erica Synths, a successful company that develops, manufactures, and exports electronic music instruments. They are used by thousands of people around the world — some worth mentioning include Martin Gore from the English electronic band Depeche Mode and the famous German composer Hans Zimmer.
Erica Synths' main export products are modular synthesizers — they're played in every corner of the world, covering every continent except Antarctica.
Girts strongly believes that electronic music technologies are the best combination of creativity and engineering. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx"
