Elevate your music practice with customizable backing tracks generated with audio from real instruments (guitar, mandolin, and standup bass). Strum Machine can play any chord progression, in any key, at any speed. It's the only backing-track app built specifically for players of bluegrass, old-time, fiddle tunes, and other such genres. (Although it works pretty good for some jazz/swing now, too!) Why musicians of all levels love Strum Machine: • Realistic Sound: Backing tracks are assembled in real time from studio-quality instrument recordings. • Quick Adjustments: Instantly adjust the speed/tempo, change the key, loop part of a song, etc. • Auto-Speedup: Gradually increase the BPM at the end of every repetition for training purposes. • Chord Reference: Clean, beautiful chord charts, which can be displayed in letters or numbers (i.e. "1-4-5"). • Extensive Library: Over 1,300 songs (mostly from bluegrass and old-time) ready to go, with thousands more posted on the community forum. • Simple Song Editor: Add your own songs (or edit existing ones) in minutes. Almost every chord you can play on a guitar is available for use. • Customize the Band: Choose from a variety of built-in band styles, then optionally customize each instrument individually – adjust the strumming pattern, add automatic bass runs, and more. • Organize & Share: Create song lists for practicing or even performing, and share them with your friends or on the community forum. • Cross-Platform: Sync your custom songs, lists, and preferences with any device you use Strum Machine on: phone, tablet, or computer. (It works offline, too!) • Responsive Support: If you run into any problems or have questions, write us an email or post a message on the forum and someone will get back to you within a few days! Strum Machine is under active development and we're always working on ways to make the app even more useful to our users... while keeping it uncluttered and intuitive first and foremost.

Turn your Divoom Pixoo 64 into a living now-playing display. PixelFlow streams album art, animated clocks, and local weather straight to the 64×64 LED panel over Wi-Fi — no account, no clutter, just your music on the wall. Set it on your desk or shelf and let it show whatever you're listening to, in real time. NOW PLAYING • See the cover of whatever's playing in Apple Music, scaled beautifully to the panel. • Not on your phone? Let Shazam listen and identify music in the room — Spotify, a record player, the TV, a café — and pull up the artwork automatically. • Optional lo-fi pixel-art styles: Game Boy, PICO-8, NES, CRT ramps and more, with retro ordered dithering — or keep the cover crisp. • Analog or digital clocks that crossfade with the art, a scrolling artist & title, and a song-progress bar. • Or hand off to the Pixoo's own built-in audio visualizer. CLOCKS • A collection of animated 64×64 clock faces — LCD, split-flap flip, matrix and more. • They tint themselves to match your album's colors. WEATHER • Local conditions powered by Apple Weather — current, hourly, daily and details, with smooth mosaic transitions. EFFORTLESS SETUP • Finds your Pixoo 64 automatically on the same Wi-Fi — or just enter its IP. • Preview everything live on your phone before you even connect a device. • "Dim screen" keeps it running while your phone sleeps, to save battery.

Verdict
