Fast cable drawing
Hover over gear, drag from the connection dot, and attach the cable to another device without prebuilding every port.
GearPatch
Stage-ready signal flow diagrams.
Build clear, printable wiring diagrams for live sound, DJ setups, home studios, and venue handoffs. Drag gear onto the canvas, connect cables from the nearest edge, label terminals, and export the result as PDF, PNG, SVG, or JSON.
Why it helps
Less guessing before load-in.
GearPatch is made for the messy middle between a stage plot, an input list, and a cable checklist. It keeps the diagram visual enough for performers and detailed enough for engineers.
Readable terminal badges
Show the role, connector shape, and gender at each end: Audio out, Line in, XLR M, RCA F, USB-C, MIDI, SpeakON, or a custom label.
Signal-aware lines
Use color, dashed lines, double lines, and direction arrows to separate analog audio, digital links, MIDI, speaker lines, or stereo pairs.
Local-first by default
Autosave and history live in the browser. You decide when to export or share a file.
Workflow
From setup idea to venue handoff.
- Add gear. Pick microphones, synths, mixers, interfaces, DJ gear, amplifiers, and speakers from the Library.
- Patch cables. Connect objects from the closest edge and keep labels away from overlaps.
- Describe the signal. Set terminal names, connector shapes, male/female ends, line style, color, and direction.
- Export the handoff. Send a tight-margin PDF to a venue, keep JSON for editing, or use PNG/SVG for documentation.
Use cases
Built for practical live situations.
Venue advance sheets
Share what connects to the stagebox, what returns to monitors, and which adapters may be needed before show day.
DJ and electronic live rigs
Document CDJs, turntables, mixers, interfaces, laptops, MIDI controllers, drum machines, and stereo outputs in one view.
Band and backline notes
Clarify vocal mics, DI boxes, guitar amps, bass amps, monitor wedges, and main speaker paths for the people setting the stage.
Support
Free to use, built with care.
GearPatch is free to use. If it saves you time before load-in, you can support ongoing development via PayPal.
