You can find a demo previously posted here.

"From the SOMA website:

MESSEIVER is an irrational device for exploring the world of primal, wild radio reception – the way it was first experienced by the pioneers of radiocommunication.

MESSEIVER – is a shortwave receiver that is capable of receiving different stations from all around the Earth. Its peculiarity is that it doesn’t have the classic input tuning circuit, which lets you select a single station. Instead, it captures a big part of radio ether as it is. This way you can listen to many radio stations at once from around the globe. The set of stations that you can hear, their loudness and sound are defined by numbers of constantly changing global natural parameters. Weather, solar activity, cosmic particles, clouds and dozens of other phenomena define radio waves propagation, turning the world into a global DJ that makes a unique mix of radio stations here and now, exclusively for you. More details you can find in the manual and demo video.

MESSEIVER has a luxury vintage handmade build with brass inlay, wide range old school speaker, custom coil, NOS germanium diodes, vintage neon bulb and other things which make the impression and vibes of it unique."

ERICA SYNTHS HEXDRUMS 09 // LØSTLVLS


video upload by LØSTLVLS

"A slightly dirtier HexDrums workout today, this time with the Master drive gain all the way down but at 100% for a slight definition boost. I think this is my favourite setting. Definitely makes things sound hairier without going into mangled territory.

Apologies for when my head gets in the way of the camera - will attempt to stay further back in the future. :)

Check out my sample packs on Bandcamp - loads of vintage and modern gear (leaning towards drum machines) with kits, sample chains and presets. All ethically-sourced and locally-grown here in the lab in Bristol, UK: https://lostlvls.bandcamp.com/"

Mos-lab & Scrotum Lab "The 2500 adventure"


video upload by batchas

"I skipped the part about making my matrix and the all process which took weeks and weeks behind the choice of pins instead of switches, but I might come back to it and do a video next year. Time will tell. Meanwhile here I'm looking back at the nice and positive moments I had with this 2500 clone, from receiving the modules up to the latest patch I did this year."

Introducing ADDAC System Servo Controller


video upload by ADDAC System



"At ADDAC we always admired the geniality of Neil Young’s Whizzer, way ahead of its time, a great example of how great ingenuity and engineering can come together to make something great.

Inspired by its motor controlled method we created a standalone solution featuring 8 Servo outputs to control any knob on any amplifier, guitar pedal, rack gear, etc. Bottom line any hardware that has a knob that needs to be controlled/sequenced/automated externally.

The idea behind it was to create a device that would open the possibility to control any knob, any physical knob, be it from a musical device or any other tech appliance that “needs” to be controlled, for musical, artistic or automation purposes.

Our solution comes with a Servo Connector that screws into any compatible physical potentiometer, a coupler connects the motor shaft to the target knob which will turn as the Servo turns.
We use servo motors which can be digitally controlled and move to a precise angle. The motors are controlled by a microcontroller that receives MIDI signals or the internal Expression Pedals and converts these signals to the 270 degree Servo motor range.
Each expression pedal input features 2 knobs: MINimum and MAXimum. These are used to set the range of action of the expression pedal, allowing to dial the range to any sweet spot desired. Raising the MINimum knob above the MAXimum knob inverts the Servo range.

It features MIDI over USB-C, Bluetooth MIDI, and a 3.5mm MIDI IN jack. MIDI can come from any of the 3 sources at the same time as long as they don’t overlap the servos channels being controlled."

Source Audio Encounter Ambient Delay / Reverb with Synths (no talking)


video upload by Bonedo Synthesizers

"In this video we take a close look at the Source Audio Encounter SA-264 Delay & Reverb — a versatile dual-engine effects pedal that combines lush reverb textures with rhythmic delay patterns in one compact unit. Its intuitive layout and powerful DSP let you craft everything from ambient wash and spacey trails to punchy, rhythmic echoes with ease.

With separate controls for delay and reverb along with onboard modulation, tempo sync, presets and expression control options, Encounter is designed for players who want deep sound shaping without a complex menu dive. Whether you’re adding depth to clean tones or sculpting experimental atmospheres, it delivers inspiring sounds for studio and stage."

The Casio FZ-1 Is the Hardest-Hitting Vintage Sampler Nobody Talks About


video upload by Espen Kraft

"The Casio FZ-1 sampler from 1987. Here represented with its module version FZ-10M.
This demo song is made with only custom samples from it.
Some of the screenshots are from my in-depth video tutorial no longer available on my channel.
If you're interested in any of my older long video tutorials they can be purchased from me directly on email or Patreon."

Alt exploration: Leon engaged


video upload by Uncertain Music Corps

"Leon switches in theremin like control courtesy of two banks of light sensititive resistors. The ones on the left control amplitude, the right side controls pitch of oscillators 2 to 5 (Oscillator 1 is a sine drone). It's a bit too wayward to play melodically with any consistency but it's very good for some nostalgic electro-cutup kind of thing.
Obviously quite a lot of cross modulation going on in the pin matrix here"

"Hardcore techno is cool but sometimes you just wanna chill. The Moduleur can be gentle too."
