'I’ve used a lot of synths over the years but this one is something different… it’s a strange instrument. It’s small, much smaller than it appears in photos: it is part synth, part drum machine, part multi-track sequencer. I’m still figuring it all out but initial impressions are that it’s very unpredictable and slightly unstable… but in a good way.'"

is a special Eurorack module designed to generate the warm, deep sound of an Indian bamboo flute — the Bansuri. Rather than being a simple oscillator, it behaves like a resonant physical model that responds very organically to control and performance gestures. The sound can be shaped in two main ways: 1. Control Voltage (CV) All core parameters can be controlled with CV, allowing the module to integrate fully into a Eurorack system. This makes it possible to modulate pitch, tone, and expression dynamically using sequencers, envelopes, LFOs, or other modules. 2. Light-Sensitive Sensors What makes the Indian Resonator 4 truly unique is the inclusion of three light-sensitive sensors. These sensors react to changes in light and shadow and directly influence the flute sound. By moving your hands over the sensors, you can subtly or dramatically alter the tone, airflow character, and resonance — much like the finger and breath control of a real flute player. A dedicated switch allows you to turn the sensors on or off, so you can choose between: •
Pure CV control • Sensor-based performance control •
Or a combination of both Playing Experience The module rewards exploration. You typically start by finding a sweet spot in the sound — a resonant, expressive tone that feels alive. From there, you bring the sound to life using CV modulation or by performing with your hands over the sensors. There are many beautiful and unexpected sounds inside the Indian Resonator 4, but they don’t all reveal themselves immediately. It’s an instrument that invites patience and experimentation — the more time you spend with it, the more expressive it becomes. sice 15 HP
"✨ The Ritual — Let the Flame Speak ✨ The Ritual is not just an instrument. It is a presence — a small, mysterious machine that invites sound, light, and spirit to merge into one living moment. At its core, The Ritual offers two elemental voices: a warm, crackling texture like burning wood, and a deep, sub-harmonic bass that vibrates through the body. Two outputs, two energies, both ready to shape the atmosphere of your space. But the true magic lies in the heart of the machine. In the center burns a candle. Three light-sensitive sensors observe the living flame — every flicker, every breath of air, every tiny movement of light. The flame becomes the conductor, shaping rhythm, modulation, and tone. It decides the pulse. It guides the sound. It becomes an oracle of vibration. With control voltage input, three intuitive potentiometers, and full compatibility with stand-alone setups, pedal chains, and Eurorack systems, The Ritual integrates effortlessly into any sonic temple you create. Add a touch of delay, let the harmonics bloom, and suddenly the sound becomes something else — psychedelic, hypnotic, deeply alive. A soundscape where chaos becomes beauty, and the smallest movement of fire transforms the entire universe of tone. Hand-crafted by Error Instruments, built in rugged Bricky format, The Ritual invites you to surrender your control and let the flame speak. Light the candle. Start The Ritual. Let the fire shape your sound"

Meet the Feedback Mixer — a five-input mixer with a twist.
At first glance, it works like a regular compact mixer. But hidden inside is a wild feature: an extra output with extremely high gain.
Feed this output back into the mixer and things start to get beautifully chaotic — intense distortion, bit-crushed textures, and raw, unpredictable feedback tones.
When pushed, it can even self-oscillate with no input, creating wild, evolving soundscapes on its own.
The magic happens when you blend this feedback madness with other sounds — it can add grit, energy, and edge to anything, especially drums or Acid-style basslines.
• 6HP wide – small but powerful
• Extreme gain for raw feedback experiments
• Perfect for distortion, noise, and texture creation
• Available assembled or as a DIY workshop kit
• Affordable and seriously fun
Get ready for crunch, chaos, and creativity — the Error Mixer is not your average mixer."
Solar Installation is an experimental synthesizer — a bridge between art, sound, and technology. It reimagines how we interact with music, offering a different and deeply artistic way to explore and create sounds.
At its core lies a patch bay that opens up endless sonic possibilities. By experimenting with its connections, you can discover countless “sweet spots” where unexpected textures and tones emerge. The engine itself is alive with movement, evolving harmonics, and shifting layers of sound.
An integrated effects processor lets you transform these tones even further, adding lo-fi echoes, delays, and atmospheric modulations to shape entirely new sonic landscapes.
What truly sets Solar Installation apart is its dual-mode oscillators. Each of the four oscillators can be controlled in two unique ways:
• Precision Mode – using traditional potentiometers for accurate, tactile manipulation.
• Light Interaction Mode – using highly sensitive light sensors that respond to movement and changes in illumination.
This makes the instrument behave like an interactive installation. By positioning it in different lighting environments or allowing natural shadows to play across its sensors, the machine evolves on its own, creating ever-changing, generative music.
Sometimes, it behaves like a futuristic music box — a self-driven system producing evolving patterns, unexpected harmonies, and “happy accidents.” It invites you to let go of control and embrace the beauty of randomness, where sound becomes an organic, living experience.
Solar Installation exists between instrument and sculpture, science and art, intention and chaos. It’s not just about making music — it’s about exploring possibilities.
Dark Marie represents all things that are special about Error Instruments. Their signature box, capable of making a range of experimental sounds. From stacked lofi melodies, resonant drones, to all out digital madness, Dark Marie will prove to be full of surprises. Its modular architecture and oversized alligator clips make for a very fun experience as you embrace the freedom of rerouting signals and discovering new sonic possibilities. There is also a pt2399 style delay that can be used with external audio signals. Dark Marie is available now at Noisebug"
"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.
