Cosmolab: Rapid audio hardware prototyping #faselunare

video upload by Floyd Steinberg

"The #cosmolab by #faselunare ( https://sndmt.link/cosmolab-fs ), based on the #daisyseed #mpu, is a development board for audio projects: synthesizers, effects pedals, sequencers, modular gear, samplers, groove boxes - whatever you can think of. In this video, I walk through the functions and features and create a mod reverb with this board.

Mystery Synth in Norwegian Vintage Synthesizer 70's and 80's Dreams Full Album

video upload by Kaj Roger Willumsen

This one was spotted and sent in via Ivan Trajkovic aka dejayiwan. Note the video is from 11 years ago so not AI. Could be a render for a soft synth or other though. Could be DIY, but note the touch panel or screen. According to the YouTube comments "Picture is only for cover. Not sure which synth it is. Will try to find out." There was no follow-up that I could find after that aside from mention the album itself mainly features Arturia. You can find a list of hardware synths and some harware synth spotting in this previous post featuring Dreamland. If you know what that blue synth above is, feel free to leave a comment at the bottom of this post, or send email to matrixsynth at gmail.com and I'll update the post with anything definitive. BTW, you can find additonal Mystery Synths via the Mystery Synths label here. There have only been 23 including this one, to date, since 2005. Update: answer in the comments of this post below. That was quick.

Here's the video description for the above:

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

Parts List:
Teensy 4.1 – https://www.sparkfun.com/teensy-4-1-w...

Magicós - double-necked synth guitar

video upload by Love Hultén

"In LH Labs, demonstrating Magicós 2 - A triangular oddity born from deranged imagination and psychedelic fandom. Somewhere inside, the voice of Alexis Mardas. Mellotron leads and divine drones, a double-necked wonder indeed. A nothing box plugged into the crystalline emitter, chakras align. In the detachable base, reverse delay/ethereal glow combined with fuzz that filter signals into a carpet of sonic moss.

Neck 1: Tangerine (1010music)
Neck 2: Lemondrop (1010music)
Detachable base: Lore (walrus audio effects) and TARs (collision devices)"

Magicós - The Wanderer

video upload by Love Hultén

"In a sweeter universe, a sweeter apple grew and dominated mind-expanding technology. Far from the obsidian slabs, a sacred geometry spawns out of the ruined columns of Athens. Magicós appears to the wanderer, ready to transmit and teleport them to fields beyond the realms we know…"

A.I. Experiments: The Infinite Drum Machine

video upload by Google for Developers

"Check out https://g.co/aiexperiments to learn more.

Sounds are complex and vary widely. This experiment uses machine learning to organize thousands of everyday sounds. The computer wasn’t given any descriptions or tags – only the audio. Using a technique called t-SNE, the computer placed similar sounds closer together. You can use the map to explore neighborhoods of similar sounds and even make beats using the drum sequencer. http://g.co/aiexperiments

Built by Kyle McDonald, Manny Tan, Yotam Mann, and friends at Google Creative Lab. Thanks to the London Philharmonia for contributing some sounds to this project. t-SNE animation featured in video by Gene Kogan.

"This is my first pass through the Super JX-10 editor, just wired all the pots, sliders, display, buttons etc into the mux and MCP chips. All programmed up for testing. A lot more to do and test as it doesn't do anything with upper and lower sections yet or send out any NRPN or sysex messages."

Low Gain Live @ Twin City Synth Meet 11-16-25

video upload by LowgainElectronics

"Live improvised performance for the Fall Edition of the Twin City Synth Meet in Minneapolis, MN. 4-5 voices on a 2 panel Low-Gain Electronics prototype 4U Modular system. 2 outputs from the modular one containing the 4-5 voices, the other as an "aux" send to the Fieldtone Box of Uncertainty. Aux 1 & 2 on mixer were Chase Bliss Mood MK2 (aux 1) and Endorphins Evil Pet (aux 2) (just used as simple reverb). Both stereo aux were returned on channels on the mixer. That's it!

DIY Solar Noise Synth

video upload by Musical Miscellany

"Inspired by one of ‪@zurowetz‬ videos, I decided to make a simple DIY noise synth from a solar garden statue. I added an audio transformer to boost the signal and strip out the DC offset but it's a super easy build. You just need a jack, an audio transformer, a little bit of wire, and an animal statue.

See the original video here:
