PatchLens
Read full descriptionHide full description
Never lose a great patch again. Photograph your synth, pedal, or semi-modular rig, mark the knobs and jacks that matter, and recall the exact sound in seconds. The demo and 3 patch records stay free; Pro Lifetime is a one-time unlock. Every musician knows the feeling: you spend an hour dialing in the perfect sound, move on, and can never quite find it again. PatchLens turns that moment into a permanent, searchable record: take a photo, tap the knobs and jacks that matter, add the values and notes that made it work, and it's yours forever. Take or import a photo, mark the knobs and jacks that matter, add values and notes, then search your local patch library later. Optional on-device text recognition can suggest visible panel labels, but you stay in control of every saved value. PatchLens does not require an account, does not upload your photos, and does not promise automatic universal knob or cable detection. Pro Lifetime is a one-time in-app purchase that unlocks the full local patch library, on-device OCR label assist, and recall-sheet sharing. The bundled demo and 3 patch records stay free.
