A Hybrid Eurorack Performance System with ALX-106 from WMD // Machina Bristronica DivKid Discussions

video upload by DivKid

"Here Alex from WMD ‘ALX-106’ joins me on the DivKid Discussions stage at Machina Bristronica, back in 2023 this one, to chat WMD Clutch (their hi hat module) and to demonstrate the WMD Metron’s ability to sequence and perform alongside other WMD (and non WMD) modules in Alex’s hybrid Eurorack performance rig. The combo of laptop, controller & Eurorack is a house music performance machine! Impressive."

Beyond the detailed, instantly playable performances, this collection also opens up a universe of building blocks for sound exploration. Each program, wave sequence, lane, effects preset, and sample functions as a unique piece in the Wavestate’s intricate puzzle - elements that can be swapped, layered, and re-shaped to reveal entirely new sonic pictures. Whether you’re crafting fresh performances from the ground up or mutating existing ones, these modular components empower you to bend the Wavestate engine to your imagination, turning every tweak into a new creative discovery.

"We wanted to push the boundaries of what the Wavestate is capable of," says Fernando Abreu, lead sound designer at Ocean Swift. "With Ocean State, we’ve created a universe of sound that is both instantly inspiring and deeply customizable. We can’t wait to hear the music that the community will create with these new sounds."

Discover the POWER of Feedback with Isobar's Umbra

video upload by Metamyther

"Discover Umbra, the cutting-edge stereo feedback accumulator designed for adventurous sound designers, new from Isobar. With its unique approach to feedback through a send and return effect loop, Umbra opens up massive sonic possibilities, delivering everything from subtle textures to chaotic walls of sound."

00:00 - Intro
01:20 - Vhikk X Example
04:46 - Drum Example
06:49 - Saturation
07:35 - Multigrain
08:17 - Cursus Melody

"Umbra is a dual channel feedback processor with three discrete transistor core VCA pairs. Route any eurorack-level effects, compressors or filters through its send/return paths to create feedback loops ranging from subtle textured echoes to howling walls of sound. The input level VCA is positioned before the feedback circuit, allowing time based sounds to fade naturally when the VCA is closed. A soft clipping stage after all feedback keeps levels controlled while adding nonlinearities and character. The left-right channel normalling allows for both mono-to-stereo or true stereo operation.

Features:
- Discrete transistor core VCAs for input gain (L and R), VCA pair for return gain, and VCA pair for feedback amount.
- Switchable between stereo operation and serial mono operation, where the output of the left channel enters the input on the right channel, doubling up on feedback and processing, indicated by the color of the LEDs. Orange L and R channels = Stereo operation, Orange L channel, Blue R channel = Serial operation
- Asymmetric diode soft clipping distortion at output.
Level LEDs for input level and return level, to keep feedback, drive and gain under control.

Uses:
- Adding a filter, filter bank, delay, reverb, waveshaper, or any other effect into the feedback loop.
- Heavy soft clipping distortion.
- No input feedback mixing.
- 3 stage VCA with distortion"

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:"

The Tiny Modular Synth That Stole The Show

video upload by EZBOT

"Building a modular system is a tedious and often expensive experience. Just when you think you’ve collected all the modules you dreamed of, you find yourself swapping them out for the next new thing. But every once in a while, you land on an idea that sticks—one that feels so good you might even leave it patched for a very long time. That’s exactly what happened with this small modular case, which I paired with the Digitakt II, Digitone II, and the Elektron Octatrack. The purpose of the case was to give me a sound palette larger than life—something I could play with my hands, not just with voltage or MIDI."
