What is it?

This is a meticulously crafted DIY replica of the iconic monome grid 128 controller (16×8 configuration). Designed for musicians, sonic explorers, and creative coders, it faithfully recreates the essential monome grid experience while adding modern capabilities. The device features 128 tactile silicone buttons with 16-level varibright LEDs, USB Type-C connectivity, and an incredibly slim profile of just 12.5mm thickness (9mm middle frame). Available in two variants: a premium CNC-machined aluminum alloy edition or a high-quality 3D-printed case using Kexcelled artistic filament with metallic aesthetics. Each unit carries an independent serial number and employs gold-plated PCBs for superior durability and signal integrity. The controller runs firmware version 1.2.0, which introduces compatibility with monome's revolutionary iii scripting system (official release 250201/1.0.0), allowing the grid to operate as a standalone device running custom Lua scripts—transforming it from a passive controller into an intelligent musical instrument. This enables direct USB-MIDI functionality, autonomous sequencing, and user-programmable behaviors without requiring a connected computer or norns device. Full compatibility spans: norns (approximately 50% of scripts support grid) serialosc (Mac Intel/M1, Windows 10/11, Linux/Raspberry Pi) Eurorack modules (Teletype, Ansible, VCV Rack) Standalone MIDI controller mode iii scripting environment (Lua-based, like crow)

Why did you make it?

The project originated from personal necessity: after building a norns system, the creator discovered that the grid controller was not merely an accessory but an essential extension of the norns experience—yet original monome grids have become increasingly scarce and expensive. This DIY initiative was launched to make the grid ecosystem accessible to more creators while maintaining the highest possible compatibility and build quality. Announced in July 2024 and first shipped in August 2024, the project has evolved through extensive community testing and firmware refinement. The December 2025 v1.2.0 firmware represents a major milestone, achieving full compatibility with monome's official iii-1.0.0 release while preserving legacy serialosc support. The development was significantly accelerated by a dedicated community member ("Jidi") who provided an Ansible module for testing, enabling rapid cross-platform support verification. The creator's mission is to democratize access to the monome ecosystem while fostering a supportive community. This is reflected in the comprehensive service package: 24-hour trial period (for non-aluminum versions), one-year warranty, lifetime firmware updates, installation support, and an active user community. The project also offers future-proofing through upgrade paths to 16×16 configuration and case refurbishment services.

What makes it special?

Unmatched Compatibility: This clone is currently the most comprehensively tested grid replica available, verified to work seamlessly across the entire monome ecosystem—norns, serialosc (all major platforms), Teletype, Ansible, and the new iii scripting system. It's also designed to pair perfectly with the creator's Arc clone for a complete, unified monome experience. Standalone Intelligence: Unlike traditional grid controllers, firmware v1.2.0 transforms the device into a standalone instrument via the iii scripting system. Upload and store Lua scripts directly to the grid's internal memory; scripts execute on startup, enabling autonomous MIDI sequencing, custom control surfaces, and intelligent behaviors without external computation—functionality previously exclusive to norns or crow. Exceptional Hardware Quality: The aluminum version features precision CNC machining with genuine aluminum construction, while the 3D-printed variant uses premium Kexcelled artistic filament that authentically mimics metallic finishes. Both versions achieve an ultra-slim 12.5mm profile (9mm frame) with gold-plated PCBs for professional-grade reliability. Individual serial numbers ensure each unit is unique. Visual Authenticity & Customization: LED colors can be tuned to simulate every historical monome grid edition, from earliest mono-bright to modern varibright implementations. Firmware v1.1.3+ unlocks full brightness control across all colors, including true white, with optimized power management to maximize LED count before requiring external power. Community-Centric Approach: 24-hour trial period (aluminum excluded) allows risk-free evaluation Lifetime firmware updates track monome's official releases and community requests Dedicated support community with active user group Upgrade path to 16×16 configuration available Free case refurbishment for first-batch users (one-time) Power Management Innovation: Firmware optimizations (v1.1.2+) ensure even the two dimmest brightness levels function under restricted USB power, addressing common reboot issues when all LEDs illuminate at maximum brightness. A recommended powered USB cable solution is available for high-brightness scenarios. Future-Ready Development: The firmware roadmap includes "screensaver" modes, potential mini-games, and expanded MIDI functionality. The December 2025 update ensures compatibility with monome's iii-1.1.0 preview features while maintaining stable API alignment with the official 1.0.0 release. Value & Accessibility: Priced at the original "first-release" level with Outlet (3D-printed micro-defect) and B-stock (official refurbished) options, this offers unprecedented access to the monome grid experience. The creator explicitly honors negotiations for those who remember the launch price and offers discounts for community members (SRG, Dawless groups).
