Present one single mobile app icon as a real App Store or Google Play icon, centered on a plain very light neutral background. Use a square 1:1 canvas, with the rounded-square iOS squircle taking up about 70 percent of the canvas width and casting a soft, subtle shadow beneath it. Build the icon around the App Type, using the Icon Concept as one bold, simple symbol centered with comfortable padding. Apply the Icon Style with restrained raised forms, gentle shading and believable soft material. Use the Color Palette with strong contrast between the icon background and symbol. Keep the silhouette crisp, instantly readable at small sizes and original in its use of negative space. Show no device, hands, mockup, text outside the icon, extra objects, detailed scene, thin lines, tiny details, glow, sparkles, lens flares, photographic textures, random lettering, watermarks or resemblance to an existing app icon, logo or mascot.
Use these details:
App Type: "Drum machine app"
Icon Concept: "A 2x2 grid of drum pads with one pad lit"
Icon Style: "Soft neumorphic"
Color Palette: "Charcoal and orange"
