I’m a touring VJ and need an iPad app that lets me mix music videos live with two decks and a crossfader. The clip library should feel instant—even with hundreds of high‑resolution videos—and show animated previews in a grid that stays buttery smooth when I scroll. During a show, I want real‑time effects like glitch and kaleidoscope that I can control with multi‑touch gestures. My clips, effect presets, and project files should sync across devices via the cloud. Please keep the app’s design clean by separating deck/effects/library state from the UI (MVC is fine).
