Tune Tangler is a simple grid for short musical ideas. Record with the built-in microphone or USB-connected audio hardware. You can also load a file from the device. Play tracks together so they stay in time, or run them independently. Use looping or a single pass — whatever you need. All recordings and settings are kept after you close the app. You can share tracks or save the whole project as a ZIP file. NAVIGATION The top bar shows the app title: the logo on the left opens the side menu; on the right, start/stop all tracks and a “⋮” menu for actions for the whole grid at once — ZIP project export/import, shared playback tweaks, trim resets, and More settings… (which also opens the side menu). The side menu lists Help, Recording, Tracks & Grid (including keyboard shortcut presets), Screen, Permissions, the maintenance area, and profiles at the bottom. WORKING THE GRID Each colored block is a quick control: tap it, or — with a keyboard connected — press the matching shortcut key. Want sliders and finer options? Hold the block — or, with an external keyboard connected, press your shortcut key together with Ctrl. Set each track’s shortcut in its details. Each grid row also has start/stop for that row and a “⋮” menu with bulk actions for every track in that row (playback mode, level, balance, speed, trim resets, delete that row’s recordings). In the side menu, pick a preset shortcut map for your keyboard: standard (PC-style, flexible grid) or the 24-key 6×4 layout. INSIDE A TRACK Trim the start and end, choose loop or single pass, set level and left/right balance, change playback speed, name the track, and assign a shortcut. Move the track on the grid, replace the audio with another file, share a recording, or clear the slot. ICONS ON THE BLOCK Icons show shortcuts, audio source, level, balance, trim, and loop mode. Open Help from the side menu for a full legend. RECORDING QUALITY Settings include file format, time resolution, bit rate (bitrate), mono or st
