Modern music is controlled by corporate lizards. Big Moon harnesses the power of the hollow moon sphere.

Big Moon Instruments builds MIDI controllers for musicians who don't want government issued pianos.

Each unit is designed, assembled, and tested in small batches. No factory floor. No shareholders. Just circuits, code, and a distrust of the mainstream.

ABSTRACTOR v2 MIDI Controller

ABSTRACTOR

v2 — midi controller

15-key chromatic grid with scale mapping and no government surveillance. Three rotary encoders control key, octave, and scale selection across 15 built-in scales. Plug in, pick a scale, and play — wrong notes don't exist, and they can't trace anything back to you.

Fits in a backpack. Works on a stage. Guaranteed not to spy on you.

Scale Lock

15 built-in scales from major to hirajoshi. The grid remaps in real time — every button plays a note that fits. The frequencies they don't want you to hear.

// 02

5×3 Grid

15 tactile buttons in a compact layout. Each one tuned to resonate with the hollow moon's natural frequency. We don't believe in coincidences.

// 03

Three Encoders

Dedicated knobs for key, octave, and scale selection. No menu diving. No screen. No corporate surveillance layer between you and your music.

// 04

USB-C MIDI

Class-compliant USB MIDI — plug into any computer, tablet, or phone and it just works. No drivers. No software phoning home. No telemetry.

// 05

Right to Repair

Standard components. No proprietary connectors. No planned obsolescence. They don't want you fixing your own instruments. We do.

// 06

Small Batch

Assembled and tested by hand in limited runs. Not mass-produced by factory drones. Not disposable. Each unit gets individual attention that the lizards can't automate away.
