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 — 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 — modules laid out with color-coded cables — 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.

GCS Model 8 is a free, pocket-sized 8-track tape DAW for iPhone. It has a full blown physics engine which runs in the background and models classic reel-to-reel machines and various formats ranging from LoFi cassette to HiFi 1" tape. The engine is the exact same as the one used in the professional desktop recording version, but still runs very nicely on iPhone. GCS Model 8 for iPhone is completely free, with no in-app purchases, subscriptions, or ads. I really want people to have the engine as a fun tool for mobile settings without any sort of catch. Features: • 8-track recording with a real tape transport (play, record, rewind, fast-forward, punch, scrub) • Analog tape physics: adjustable wow, flutter, stickiness, head gap, hiss, and age • Built-in effects and tape techniques: reverse, SOS, punch, click track, loop • Built-in instruments: A-1 Mono Synth, A-10 Poly Synth, Glissandio (Ondes Martenot style slide synth), Stage Keyboard • Voxtone Drum Machine: synthesized analog drums with a dedicated step-sequencer (MATRIX) and live-trigger (PADS) view, plus two sample-based kits (808, Acetone) • 8-pad MPC-style Pad Sampler: load your own samples or mic them in directly, with pitch, trim, and gate controls • Reels: save, load, and share your sessions • Bluetooth MIDI keyboard support • Importing recordings to hit them to tape • Sound of Sound looping (Fripp style) • Formats: cassette, 1/4", 1/2" and 1" - along with various presets •Most of the features found on the desktop version Reels you create on iPhone move over to GCS Model 8 for iPad and GCS Model 8 for Mac/Windows, which add more tracks, more effects, and full export/mixdown for when you're ready to take a session further.
