PatchMap is the fast, structured way for Eurorack players to document, search, and recreate their patches. Stop relying on blurry phone photos and scattered notes โ capture every connection in seconds and find any patch later. Fast Patch Recording Pick a module, mark an output and an input, and save the connection. Logging a full patch takes seconds, not minutes, so you can document a great sound before it slips away. Your Module Library Build a library of your rack's modules once and reuse it for every patch. Add modules with their HP, type, and I/O so your records stay accurate and consistent. Powerful Search Search your entire patch history by module name, tag, or date. The good patch you made last month is always one tap away. Signal Flow Visualization See each patch as a clean connection diagram โ modules laid out with color-coded cables โ so you can understand the routing at a glance and recreate it exactly. Tags & Notes Organize patches with tags like ambient, percussion, or drone, and add text notes to capture settings, knob positions, and ideas. Shareable Patch Cards Generate a clean patch card image and share it to Instagram, Reddit, or with friends in one tap. Privacy First PatchMap works completely offline. No account, no cloud, no data collection. Everything stays on your device. Built for modular synth players with mid-to-large systems who patch often and want to remember every great sound.
