Originally designed to enhance affordable electronic drum kits, this app bridges the gap by adding customizable samples and a powerful level mixer. Build your own kits using your own .WAV files and tailor the MIDI mapping to perfectly match your drum pads or triggers. You can even use it as a general sample player to trigger sound effects through a mixer. The app includes a starter library of classic kits—ROCK, POP, 606, 808, and 909—and makes it easy to create your own. Simply add folders of named samples via the iOS Files app or directly from your Mac or Windows computer. A customizable MIDIMAPPING.TXT file lets you assign specific MIDI note numbers to your samples, giving you total control over your setup. Both kits and mapping files are accessible through the iOS Files app or from a connected desktop. And with its ultra‑low latency, you’ll experience true real‑time responsiveness—perfect for live performance.
