Herbs and Stones Seeds - mini noise synth

video upload by Herbs and Stones

"Seeds is a DIY noise synth that will be available to build at various workshops."

https://herbs---stones.com/seeds-work...

Seeds is a portable, battery-powered noise synth.

Its operation is based on the improper use of primitive CMOS digital technology: by forcing a linear output from an integrated circuit that operates using Boolean logic, by draining it of current and pushing its inputs to their limits, organic, unpredictable, and never-replicable sounds are achieved.

Seeds is an instrument with a vast array of sounds, designed for research and experimentation.

Technical Specifications:

Power: 4 AA batteries (included in the kit)
Output: Stereo TRS minijack

DIY Minimoog Inspired Synth | A Teensy Powered Tribute

video upload by Moby Pixel

"In this video, we’re building a Teensy-powered synth inspired by the iconic Minimoog Model D, and exploring what made the original design so legendary. We’ll walk through all-the-things: oscillators, mixer, filter, envelopes, hidden features, presets, the Teensy’s USB audio setup, and how Bob Moog’s Minimoog helped shape modern subtractive synthesis.

This is my biggest project to date, and I couldn’t be happier with how it turned out! The Teensy 4.1’s built-in USB audio is sending power, MIDI, and audio over a single cable. What a time to be alive, haha! All code and build files are available on GitHub if you want to make your own. Cheers!

GitHub: https://github.com/NickCulbertson/Min...

A 6-voice polyphonic virtual analog synthesizer built with the Teensy 4.1 microcontroller, inspired by the classic Minimoog. Features comprehensive synthesis with USB audio/MIDI and intuitive menu control.

Key Features:
6-voice polyphony with 3 oscillators per voice (18 total)
6 waveforms per oscillator
Noise shared white/pink noise
24dB Moog-style ladder filter with ADSR envelopes
Independent LFO with pitch/filter/amp targets
Macro knob system - remap filter knobs to LFO controls
USB Audio + MIDI - single cable to computer
20 hardware encoders + LCD for real-time control
20 Presets - 80s Brass, Saw Keys, Bass sounds, Pads, and more
Multiple play modes - Mono, Poly, Legato with glide

"Short demo of a sequence running through the Melting Point vactrol filter. Now available on my Reverb page"

via this Reverb listing

"THIS IS A FULL DIY KIT

This kit includes everything required to build the Melting Point vactrol filter. This is a character filter that will add a lot of color to the sound.
There is a low-pass and hi-pass audio input, an audio output, 2 CV inputs and a variable level “Strike” CV input.

The feedback/resonance will begin self oscillating slightly past noon, and will continue to add more drive and color if you push it further.
Trim pot on the rear allows adjustment of CV response.

Includes a power cable and 4x M3 screws.

There is a qr code in the kit that will take you to a page with build instructions.

Please note the knobs included in the kit are different than the knobs in the finished module image."

Roland Future Design Lab and Neutone Introduce Project LYDIA

Press release follows:

A Technology Preview Exploring AI, DIY Culture, and the Future of Music Creation

Los Angeles, November 11, 2025 — Roland Future Design Lab, the advanced technologies research group of Roland Corporation, announces Project LYDIA, an audio processing platform preview created in collaboration with Neutone, developers of next-generation AI tools for musicians and artists. Project LYDIA merges Neutone’s trainable AI software with Roland’s hardware expertise, using a Raspberry Pi 5 single-board computer to deliver a compact, stage-ready prototype that reimagines DIY innovation for a new generation.

Bridging AI and DIY Creativity
Roland’s legacy in DIY music creation began in 1981 with AMDEK (Analog Music Digital Electronic Kits), a line of build-it-yourself kits that encouraged musicians to experiment with technology. Today, Roland Future Design Lab revisits that spirit, asking how modern creators can explore sound through emerging AI tools.

AI for Sound Discovery and Exploration
Powered by Neutone’s Morpho technology, Project LYDIA, named after DIY and AI, uses “neural sampling” to learn the tonal qualities of any sound and apply it to another in real time, with the sonic results ranging from highly musical to exotic and surprising. The current Project LYDIA mockup houses a Raspberry Pi 5 computer running Neutone’s special version of Morpho alongside Roland’s latest ideas for a simple, tactile control panel. Audio I/O is currently managed via a USB-connected Roland Rubix interface, with future iterations aiming to fully integrate I/O for a completely self-contained device.


AI Innovation at Roland
Project LYDIA builds on Roland’s growing exploration of AI as a creative partner for musicians. In 2024, Roland and Universal Music Group (UMG) jointly introduced the Principles for Music Creation with AI, a framework outlining shared commitments to ethical and artist-centered innovation.
“Roland has taken a leadership role globally in practicing responsible development with AI for music creation,” said Paul McCabe, Senior Vice President of Research and Innovation at Roland. “Part of being responsible is getting input from creators on what they find useful, helpful, or inspiring, and what ideas may not be welcome in their workflows. Releasing Project LYDIA as a technology preview allows us to demonstrate possibilities, seek community input, optimize, and improve.”

Shaping the Future Together
Project LYDIA debuted at the Audio Developer Conference taking place November 10 through November 12 in Bristol, UK, inviting feedback from the creative community to guide future research in AI-driven music tools. Musicians and makers can share their thoughts and ideas via a short survey here.

To learn more about the inspiration and technology behind Project LYDIA, visit Roland’s feature story on Roland Future Design Lab.

demo of the b4Modular Series 7 synthesizer part 1 / 2 : the suitcase

video upload by elektronengehirn

"The diy modular synthesizer in a suitcase which Malte Steiner developed between 2024 and 2025. The goal was to build a cheap modular system mainly for live concerts, which is repairable and can go into Checkin Luggage without much worries (something you don't do with Eurorack). So far it is used for several concerts by the projects Elektronengehirn and Notstandskomitee in Berlin and Helsinki, and local Jam sessions here in Aalborg. It is build in a Nanuk 923 case which can remove the lid, the rails are made of wood and wood screws, the front plates are 3D printed.
The system features 2 analog Oscillators / LFOs, one digital oscillator with 6 different modes, an oscillator bank with 6 square waves, triple clock module, 3 slew limiters, a lowpass filter, tone control filter, wave folder, one ring mod / wave folder, 5 VCAs, crossfader, mixer, 2 pressure sensors, a trigger button, unity and gates mixer.
See it in action at this Notstandskomitee concert in Helsinki:"

"In this video we’ll break down how common types of modulation for sound synthesis work, how to make the most of them creatively and musically. We’ll do so while demoing the new Triple Mod DIY module from Thonk. Whether it’s creating multi-phonic layered patches needed multiple envelopes, understanding how a Turing Machine works and performing with it, understanding and making Sample & Hold melodic, creating chain reactions with EOC ‘end of cycle’ triggers … there’s lots in this video applicable to LOTS of other modules."
