"✨ 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"

CHROMAGENE is an all analog, stereo polyphonic synthesizer with two halves. One half is an 8 voice 2 VCO polysynth where every oscillator can be tuned independently or transposed together, the other half is a polysynth that uses the Ring Modulated output of each pair of oscillators as its signal source.
This wide range of sound sources along with two analog filters and an on-board sequencer give Chromagene a wide palette of tones and textures.
Inspired by the earliest polysynths of the 1970s, it is fully polyphonic (all 16 notes can be played at the same time), can be tuned to any scale or tuning, is multi-timbral and touch sensitive.
The instruments key contacts are Immersion Gold plated and non-corrosive.
At the top, there are 16 tuning controls for the 8 pairs of oscillators. Each tuning control has a momentary pitch bend touch sensor below, so you can articulate each note individually. The top row of tuning controls (VCO-1) also shifts the oscillator below it, but the second row of tuning controls are independent. This allows you to preserve the tonal relationship by using the top tuning controls, or change it by detuning VCO-2.
These tuning controls allow you to tune the 8 pairs of oscillators to any scale, from a standard equal tuning to any microtonal, non-western or even unison tuning.
VCO-1 has a Pulse Width Modulation control and each set of oscillators has a master tuning control and an individual LFO control.
The 8 analog ring modulators take the VCO signals and multiply their output. VCO-2 is converted to a triangle pre-ring-modulator so that the ring modulated signal is fully continuous and not binary like pseudo-ring-modulators in some synths. This means you can create virtually any waveform by carefully tuning the input VCOs, and an endless variety of tones can be generated for each note individually.
The two filters, which can be panned from mono to full stereo using the panning control, are all-analog all-transistor low-pass VCFs, with individual cutoff, resonance and envelope-mod controls. The envelope amount controls go from negative (inverted) to positive. VCF-1 has mixer controls for VCO-1 and 2, and VCF-2, which is for the Ring modulated notes, has LFO cutoff modulation and Panning.
The 16 independent envelope generators have Attack, Decay, Sustain and Release controls. The sequencer can be internally or externally clocked. Custom sequencer configurations can be set up, get in touch.
The synthesizer is built into a hand-made wood case.

"When the Cocoquantus2 first appeared, it didn’t just find an audience—it created one. Musicians, experimentalists, producers, and curious tinkerers fell in love with its organic chaos, character, and uncanny ability to turn accidents into art. It became a modern cult instrument because you couldn’t play it without forming a relationship with it.
Café Quantum continues that lineage with reverence—then boldly invents a new chapter.
At its core, Café Quantum preserves the tactile immediacy and playful unpredictability of the Coco ecosystem. But surrounding that familiar heart are entirely new tools designed to make the instrument feel more alive, more intelligent, and more expressive.
One of the biggest leaps is the open-source programmable engine. For the first time, players can write their own behaviors—little sonic personalities— at the Cafe modules, one for each side, and the Quantum module can carry them out by patching points. Whether it’s generative patches, evolving modulation, rhythmic structures, or strange autonomous rituals, the instrument becomes a creative partner. And thanks to the dedicated banana sockets, these behaviors integrate directly into the patch ecosystem. The Cafe module becomes a blank page for your imagination, shaped as far as your coding skills can carry you
The preamp has grown up too. Now it features a Norton gain character and adds a VCA input, making external dynamics, sidechaining, and voltage-controlled level manipulation feel effortless. On top of the newly redesigned preamp features you still have the envelope follower that opens the door to all sorts of expressive interactions between incoming audio and internal modulation.
Then comes the new magic trick: A radio-based gestural controller sits atop the entire system, allowing 4 hands-free modulation reminiscent of a theremin. Move in space, and the instrument responds—pitch, delay time, grain density, feedback paths, whatever you choose. It transforms performance from knob-twisting to full-body expression."

Altered State Machines history
Hi, we're Jesse and Ed.
Jesse became fascinated with modular synthesis around 2016 and went back to school as an electronic engineering technician to learn how to repair and create his own eurorack modules.
Altered State Machines grew out of Jesse's first project, the Aristotle sequencer which is now in its fifth iteration. Jesse is our electronics and hardware mastermind. Ed joined forces to twiddle bits with the software.
"SCRATCH FIGHTER is a new musical instrument based on scratch performance using a turntable.
Although the operation is the same as scratching with a turntable, it is relatively easy to play scratches. In addition to the built-in samples, there are three sampling slots.
"First day with the WOAS, sending a clock to the Pluto. Double tapping the Wavesnap button samples a distorted version of the machine’s total output into channel 4 and then plays it back. Lovely random fun"
"FOUR is a 4 oscillator ( surprisingly) drone synth/utility instrument.
The 4 square wave generators are grouped into pairs and routed through 1 of 4 NOR logic gates. The outputs of the logic gates can then be mixed together to create stacked drones and chords.
FOUR can also be used as a CV source or to gate/trigger other equipment.
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.
"The DecadeBridge Triad is a unique little Synth module that generates drones, rhythms, noises and glitches - it sounds, to me at least, like a haunted arcade in the 80s - malfunctioning machines, wailing, whirring and bleeping. It's based on a trio of analog oscillators arranged in a fairly unique, raw and unpredictable arrangement. It works great as part of a drone or noise setup, makes for excellent sample fodder, and thanks to the neat "reset" input it can play along with drum machines and sequencers (especially paired with a little low-pass gate).
