"The Future of Music – In the Vision of Paul Tas

Imagine a future where music isn’t something you listen to, but something you create—not with instruments, but with sound itself.

Not songs. Not tracks. But pure, raw, living sound.

This is the vision behind Quantum Cloud, a prototype sound installation and device. It’s not about listening to pre-made music. It’s about building your own sonic world—100% personalized, created in real-time, with machines and light.

Quantum Cloud: A New Kind of Sound Machine

Developed by Error Instruments, this is a highly experimental modular synthesizer—part sculpture, part sound lab. Built around four light-controlled oscillators, it responds to light and to itself. The oscillators can motivate, influence, and synchronize with each other. It includes a unique echo effect, adding depth and motion to your sonic exploration.

This is not just an instrument. It’s a sound experience.
• Patchable and modular
• Fully interactive
• Designed to evolve and inspire
• Meant for the curious, the creators, and the dreamers

Whether placed in your home as a sound sculpture or built at a DIY workshop, the idea is simple: sound becomes yours.

You don’t play music—you create your sound.

Affordable, Experimental, Accessible

We are developing a Do-It-Yourself kit for under €200. You can build it at home, or join a workshop and dive deep into experimental sound-making.

This is just the beginning.

1. Bristronica 24: MyVolts The Silent Alchemist Nears Shipping

We caught up with Caroline who gave us the latest update to the *Silent Alchemist*, a versatile power hub designed for musicians. Featuring five isolated USB-C outputs and a high-wattage sixth output capable of delivering 100 watts, the device can power a Mac with the remaining outputs providing 20 watts each. Its independent circuits ensure noise-free operation, catering to a variety of devices including the Dreadbox module and Sysmo slope generator.

The Silent Alchemist uses innovative step-up power tips to convert USB-C input to the correct voltage for various devices. There's also new feature: an uninterruptible power supply allowing seamless transition between wall and power bank sources. Also introduced were updated cables, such as silver candy cords and floating ring TRS to TS cables, expanding connection flexibility. The Silent Alchemist is expected to be available in December with a competitive pricing strategy.

2. Bristronica 24: Circuit Happy ML2M Clock Sync module updates

At Bristronica 2024, we caught up with the creator of the *ML2M*, who introduced us to the latest version. The ML2M is a compact Eurorack module with Wi-Fi capabilities, allowing seamless synchronization with Ableton Live, Bitwig Studio, and iOS music apps using Ableton Link without the need for cables. It either connects to an existing network or creates its own, ensuring robust sync even in environments with unreliable Wi-Fi. The module, which retains its 2HP size, now features MIDI integration through TRS jacks. Users can access a web interface to configure each output for different clock divisions and reset triggers, making setup straightforward and flexible.

Alongside the ML2M, there's also the Missing Link Junior. This desktop version offers the same functionality but in a box format, complete with MIDI and CV clock outputs. Both products are now accessible, with a starting price of $250.

3. Bristronica 24: Archaea Exchange Patching Module

At Machina Bristronica 2024, we caught up with Arran from ‪@archaea_modular_synthesis‬ who presented the *Exchange Module*. This programmable patcher, a year in the making, evolved from its early prototype stage to a fully functional module. Arran explained how the Exchange can route synth voices via a beam controller and three exchange modules installed within the skiff, allowing for versatile patching. Operating like a matrix patchbay, it enables users to select inputs and outputs with the push of a button, create presets, and chain multiple modules for synchronized patching.

Communication between the modules occurs over the Eurorack power bus as well as over MIDI via the USB-C connection. The Exchange maintains analog integrity, ensuring there’s no conversion latency. The forthcoming release expected in late November 2024, includes a USB-driven editor for enhanced control capabilities.

ARP Omni-2 with Aftertouch + S&H Mod

Note: Auction links are affiliate links for which the site may be compensated.
video upload by New England Analog Archives

Note this demo is from 7 years ago.

"This video features an ARP Omni 2 synthesizer that has been modified with a custom LFO expander daughterboard. The PCB comes assembled and measures 2.7 x 3.2 cm.
This upgrade is simple to install, and it provides the LFO with 2 additional waveforms. A 3-position toggle switch controls the waveform selection. An adhesive-backed overlay decal is provided with the kit. The switch will allow sine, square, and random LFO waveforms to be selected. Kit includes instructions for expanding the range of Omni 2 VCF so that it can self-oscillate. This modification greatly expands the sonic possibilities of the ARP Omni. This kit will work on ARP Omni 1 as well. It can also be used to add an auxiliary sample and hold waveform to ARP Axxe, Odyssey, and Quadra LFOs."

via this listing

"The unit has been well maintained and has had the following work/mods done:

Replaced the noisy ARP power supply with a Power One linear supply

Unit was completely recapped in 2015.

All analog ICs and digital ICs were replaced

All sliders removed and restored. All now move smoothly.

Slider caps replaced with new ones.

Pratt Read keyboard bushings replaced in 2015.

Aftertouch added to the keyboard.

Aftertouch amount is routed to the ACC/PEDAL slider. The aftertouch affects the VCF cutoff. Additional waveforms added to the LFO. Originally only had sine LFO. Added square and sample & hold LFO. Sample & hold is the same circuit as ARP Odyssey MK1 S&H. Sounds great. 4075 VCF module recapped and had the cutoff frequency design error corrected. (Originally there was a design error, keeping the cutoff from fully opening up)

The finish on this Omni is not pristine. When I got it, it had been neglected for years after being in storage. Cosmetically, this is a 6/10 as there is evidence of lots of use on the powder coating.

I've attached a video deomonstrating the LFO mod I did to this Omni. The unit in the video is actually this Omni, but I have since removed the LED sliders, since I thought they were annoying."

Error Instruments | Broken Tape Simulator V2

video by Cinematic Laboratory

"This video is about a small 6 HP module that can seriously trash any patch into a messy, but awesome glitch & data bending chaos. So skip this one if you're not into modular madness. It's about Error's Broken Tape Simulator V2, which has a built in light sensor you can use to short-circuit your virtual lo-fi tape machine. But after all, it's just a tool in a sound design kit and I am sure you'll love it when you spend some time with it. Especially with lots of FX in the end of chain. Have fun, and if you don't - sorry for the noise."

Buchla Dual Oscillator Model 258 258c 258r

via this auction

"Excellent condition Buchla Dual Oscillator Model 258c from Roman Filippov kit. Meticulously assembled utilizing uA726s.

Two independent voltage-controlled oscillators, continuously tunable from 5 Hz to 20 kHz. Each has two processing inputs and a frequency modulation input. Waveshapes as well as frequency can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Controls and I/O:

Processing inputs — Two processing control inputs permit multiple control of pitch without need of separate external processor.
Processing controls — Used to set desired range of frequency control. Expansion, compression, and inversion of scales are accomplished here.
Frequency modulation control — For adjusting vibrato depth or creating clangorous or bell-like tones, rich in non-harmonic partials.
Output — Signal amplitude is +4 dB. Output impedance is 600 ohms.
Oscillator frequency control — Spans the audio spectrum of 5 Hz to 20 kHz with no range switching. (Applied control voltages can extend limits to .1 Hz and 30 kHz.)
Waveshape control input — Waveshapes can be varied from sine to saw (osc 1) and sine to square (osc 2). Voltage control of waveshape enables powerful dynamic control of timbre."

Vintage Aries 300 Series Modular Synthesizer with 61 key Control Keyboard

via this auction

"What you are looking at is a special instrument.

300 Series Modules
The core of this system is five modules from the Aries 300 Series. There is one VCO module, one VCF module, one EG module, one VCA module, and one Clock/Noise/S&H generator. Yes, this is basic; here are the module names:

AR-317 VCO
AR-312 EG
AR-314 VCF
AR-316 VCA
AR-318 SH/Clock/Noise Generator
But of course, that's only the core. This system is bookended with some interesting devices. To say that it is "modified" would really be an understatement. It has been lovingly built by a lifelong musician.

The great thing about this system is that it was used by a professional musician as part of his home studio and performance rig for decades. It's often the case with these vintage units that they have aged poorly due to being left for decades in a closet or basement or whatever. But this was used consistently over its lifetime, up to the time of its builder's death. It has been played, as pieces like this need to be.

As you can see, the VCO module has been modified to include a further fine-tuned frequency control, right in the middle of the four knobs.

The Sound

There are an enormous number of modular and semi-modular systems available for musicians right now; the possibilities are almost endless. However, this has an edge that many modern synths don't have: the sound. These modules together sound much more like an ARP 2600 or vintage Moog modular than anything currently on the market. In fact, the sound of the filter is somewhere between Moog modular and early ARP filter. This probably isn't a coincidence, since Aries was a DIY synth-kit company founded by a former member of ARP in Massachusetts.

"Wired Heart" Synth Gadget by Tubbutec.de, Phirol and Hyboid (Astro Chicken Records)

Published on Sep 20, 2017 Hyboid a.k.a. Astro Chicken

Available at: https://hyboid.bandcamp.com/album/wired-at-heart

"Wired Heart features six sensors that can detect touch and humidity. Each of the sensors control the pitch of an oscillator – press harder or have sweaty hands to get a higher pitch. Each sensor serves a different function, and it is best to explore the Wired Heart Sound universe by trial and error."

"Wired Heart features six sensors that can detect touch and humidity. Each of the sensors control the pitch of an oscillator – press harder or have sweaty hands to get a higher pitch. Each sensor serves a different function, and it is best to explore the Wired Heart Sound universe by trial and error. However if you want to know what is happening, you can find some explanation below.

INTERMODULATION
If this still sounds boring to you, wait what happens when you touch several pads at once. The oscillators will begin to further cross modulate each other by the current flowing through your hands and a whole new world of awesome sounds opens up.

EXPERIMENT!
There are many more ways the heart can react to you: Try wiping it with a wet cloth, put a banana on it and see what happens, or simply blow on it – the humidity in your breath will make the oscillators sing as if you were just breathing new life into six punch-drunk sirens.
