Stop Forgetting. Start Patching.
Your personal library for documenting Eurorack modules. Photograph a faceplate,
annotate the controls, and never wonder “what does this button do?” again.
“Wait, What Does This Do?”
You bought a complex module six months ago. That mysterious 3-position switch?
You’ve forgotten which mode is which. Again.
Manual Overload
The PDF manual is 47 pages long. You just need to remember what “CV A” does when you’re patching live. There’s no time for Chapter 3.
Knowledge Scattered
You’ve got notes in your phone, bookmarked forum threads, and scribbled post-its.
Nothing’s organized. Everything’s lost.
Rackdocs makes it easy
Documentation That Actually Works
RackDocs is your visual reference library. Snap photos of your modules, mark up the controls, and create the cheat sheets you actually need.
Photo-Based Documentation
Take a photo of any module’s faceplate. Our editing tools handle rotation, cropping, and perspective correction—even if you photographed at an angle. Get it perfect without reshooting.
Smart Annotations
Nine annotation types (inputs, outputs, knobs, switches, buttons, LEDs, MIDI & USB ports and microphones) with automatic color coding. Tap a control, add a label and description, done. Zoom and pan for pixel-perfect placement.
Advanced Documentation
Document LED colors and behaviors (solid, blinking, pulsing). Multi-position switches with detailed state descriptions. Multi-step operations and combinations.
Perfect for complex modules like Maths, Plaits, or Ornament & Crime.
ModularGrid Integration
Already on ModularGrid? Paste the URL and RackDocs auto-fills the specs, downloads the faceplate image, and populates the form. Start documenting in seconds, not minutes.
Built for Serious Documenting
Power features for complex modules and detailed documentation.
Module Contexts
Document modules with multiple operational modes (alternate firmwares, shift modes, menu systems). Switch contexts to see only relevant controls. Keep complex modules organized.
Combinations
Document multi-step operations: “Hold button 1, press button 2, adjust knob 3.” Perfect for hidden features, calibration procedures, and shift functions you’ll definitely forget.
Precision Editing
Zoom, pan, pinch-to-resize. Annotations scale perfectly with the image. Adjust transparency per-module for cluttered faceplates. Copy-paste annotations to speed up documentation.
Color Schemes
Choose from four pre-designed palettes (Muted, Bright, Dark, Red Shades) or keep the defaults. Per-module customization means each faceplate can have its own aesthetic.
