"It's been ten years since I first heaved a Molten Music Monthly into the world. I've done it every month since and through thick and thin there's nothing I enjoy more. The summer is always a bit slow but I've pulled together some nice bits and bobs to mull over while applying sun cream or hiding in our synth caves.

KHARPER - Four voice experimental synth / controller for eurorack and desktop.

video upload by Cinematic Laboratory

"I can't just tell you what Kharper is. You need to fish it out yourself.
ERROR calls it the best eurorack module ever - which translates to 'this is the best thing we made so far'. In this perspective, I completely agree. This is not an error."

"Rare, One-of-a-Kind Sculptural Devices by Paul Tas

These are not your average machines. Designed and handcrafted by artist and inventor Paul Tas, each device in this exclusive collection is either:
• A limited production piece, or
• A completely unique, singular creation—no duplicates exist.

With unconventional, often surreal designs, these devices blur the line between functional object and sculpture. They may serve obscure or symbolic purposes, built more for exploration and expression than utility—think of them as machines that tell stories or instruments for imaginary tasks.

Every piece is:
• Individually constructed
• Visually striking
• Mechanically unusual
• Often part of a broader artistic vision"

Quantum cloud installation or the future of music

video upload by errorinstruments paul tas

"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.

made design by Paul Tas

Cloudbusting is a full Modular experimental synthesiser .It has 12 points that can be patched . 6 modes .Modulation points but also Audio with experimental sounds . Most famous sounds that are used for experimental purposes. as deep Drones .And also the Inspired sound of the plum . The sound of ciat lonbarde plumbutter / Rolls5 Also some weird frequency modulation . And a lot more ."

Important information about noise therapy !

video upload by errorinstruments paul tas

"It’s important when you start it up that you put the big knob in the middle . This is a trick if you don’t have sound. Because it’s an open chip and it’s circuit bending but we created it that it cannot get broke."



via Error Instruments

"Noise Therapy is a compact, experimental audio device

designed for sound exploration and real-time manipulation.

It’s not just an effect processor — it’s a self-oscillating feedback machine,

a live circuit-bending platform, and a sensor-based sound controller all in one.

• 🎛️ Real-Time Circuit Bending: Dive into unpredictable

sonic territories. The Circuit Bending Bank lets you create new sounds on the fly no

emulation here, just raw, hardware-driven sound design.

• 🔁 Self-Oscillating Feedback: Use it as a chaotic

sound generator or a responsive instrument — capable of evolving drones,

sharp glitches, and alien pulses. • 🎚️ Effect Processing: Process external

audio or internal feedback loops with a rich palette of distortion, delay,

filtering, and noise. • ✋ Sensor-Controlled Sound: A touch-sensitive

and light-reactive sensor beneath the switch opens up expressive

performance options. Interact with light or skin

contact to alter the audio in unpredictable ways. •

🎛️ Patch Bay Exploration: The modular-style patch bay

encourages creative routing and discovery. It’s full of accidents

— those magic spots that only circuit bending reveals. • 🔊 Sonic Range:

From delicate liquid drop-like sounds to harsh industrial noise,

deep ego drones, and intense distortion — this is a tool made for sound designers,

noise artists, and experimental musicians."

Error Instruments & TINRS New Kharper Prototype Eurorack Module

video upload by errorinstruments paul tas

"This model will be released 18-jun at www.errorinstruments.com.  this is the collaboration between. TINRS / Errorinstruments from Amsterdam the Netherlands."



"kHarper Electronic Harp with 4 strings

We built a physical version of the Karplus-Strong physical model for strings. There is a whole group of Karplus-Strong algos and we are using a bunch of them. We built 3*3 sound engines that are each producing four voices.

kHarper is easily epic and cinematic. Can do big bwaaps as well as slow and emotional chords. Unlike a banana.

4 strings
Every string is a voice. The strings are built out of two touch strips with an LED bar in the middle, showing you what kHarper is doing. Each string has a knob on top to set the tone and a CV -in below. You can also patch in a gate to pluck the string.

kHarper has a very wide range of sounds. You can go from wild distorted guitars to meditative soothing plinkies. Just like any other stringed instrument there are 10.000 ways to play.

Being able to touch these Karplus-Strong models adds the natural chaos of a physical manifestation. Plucking amazing.

A liquid voice. The mini version of the liquid glicher  coming

video uploads by errorinstruments paul tas

"Introducing: Liquid Voice – Experimental Oscillator & Drum Module (8HP) After the huge success of the Liquid Glitcher, we’re back with something special — a more compact edition built on the same powerful engine and signature voice.

Liquid Voice packs the same sonic punch — glitchy textures, deep sub-bass, and unique drum timbres — all in just 8HP. Despite being smaller in size, the sound is bigger than ever.

Three distinct outputs:
• Wave Out – Delivers tiny, glitchy textures and synthetic bursts.
• Sub Out – A fusion of deep sub-bass and micro-sounds.
• Drum Out – A hybrid voice created between two internal oscillators, shaped by a vactrol in a Lopez gate for that raw, organic snap.

This isn’t just a downsized version — it’s a refined and reimagined tool for experimental creators who want maximum versatility in minimal space.

Check out the demos and discover the beautiful chaos of Liquid Voice."

"Time Machine: The Happy Accident Synthesis Introducing the Time Machine, a revolutionary data synthesis device designed to transport you through different times and dimensions. This isn’t just any ordinary machine; it's a 100% happy accident machine, crafted to produce an array of unique sounds inspired by data glitches. Experience the captivating sound of circuit bending, where hardware meets software in a delightful fusion. Check out our demonstration videos to immerse yourself in the extraordinary sounds the Time Machine has to offer. Please note that the output is mono, so it’s recommended to connect directly to a mixer rather than using headphones, as the sound can be quite loud! Designed for versatility, the Time Machine is fully compatible with the Eurorack system. Additionally, what sets it apart is the ability to use its output as a control voltage source for your Eurorack setup, expanding your creative possibilities even further. Dive into the world of sound with the Time Machine, where every glitch leads to a new auditory adventure!"
