Neutral Labs - Luna (Eurorack)

This is the DIY Eurorack version of this unit.

Logic, Unbound. Meet Luna. The first serious Lunetta synthesizer.

Look beyond clean waveforms and predictable polyphony. Luna takes you back to a time when digital didn’t mean perfect. It meant raw. Inspired by the subterranean DIY culture of the 70s and 80s, Luna is a love letter to the Lunetta machines of old – living, breathing organisms built from CMOS logic chips. But where those machines were fragile experiments, Luna is a weaponised instrument of sonic confusion.

The Nervous System Exposed. True to the Neutral Labs philosophy, we don’t believe in hiding the magic behind an opaque faceplate. Luna features exposed CMOS inputs and outputs directly on the front panel. You're not simply patching cables – you are rewiring the brain of the synthesizer itself. Combine signals, bend logic, and physically intervene in the computation to create sounds that shouldn’t exist.

Rhythm is Timbre. Timbre is Rhythm. In the world of Luna, there is no difference between a sequencer and an oscillator. The same digital pulse that drives a bass line can be accelerated into a screeching lead or folded into a metallic drone.

Five oscillators provide the raw material. A chaotic array of logic blocks (XOR, NOT, AND, shift registers, counters, multiplexer) chews up those signals and spits out complex, evolving mathematical noise.

Taming the Digital Mess. Raw logic can be harsh. To turn this binary chaos into music, Luna feeds its digital soul through three organic low-pass gates. These analogue circuits impart a natural decay and percussive punch to the madness, transforming mathematical errors into bongos, plucks, and thumping basslines.

Drench it in Atmosphere. Once you’ve constructed your signal, destroy it again. Luna comes equipped with a suite of effects – distortion, delay, reverb, chorus, bitcrusher, phaser and more – to smear your logic into a wash of ambient bliss or gritty industrial texture.

Features:
• 5 oscillators
• Logic gates (2 XOR, 2 NOT, 2 AND)
• 5 logic blocks (5-step ring counter, 4-bit binary counter, 2 shift registers, 4-channel multiplexer)
• 3 touchpads that generate logic signals
• 3 channels for audio manipulation (low-pass gates with adjustable decay and switchable trigger mode, gain, tilt EQ)
• 13 audio effects freely assignable to 2 effect slots running in series (drive, delay, reverb, 6 filter types, bitcrusher, phaser, chorus, comb filter)
• CV control for effects and 2 oscillators
• MIDI control over 2 oscillators, all 3 low-pass gates, and 3 logic outputs
• 2 sequencers with up to 64 steps, syncable to clock or MIDI
• Headphone-compatible audio output

DIY-Kit-Type:
SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder. For build guide, more info, videos etc. please check the buttons below.
