Performance Sampler: Samposium

Create Music and Live Jamming

$14.99

Real-time touch-gesture sampling, live effects, and a 64-step sequencer - all yours with one purchase, no subscription required. Samposium is a performance sampler built for real-time audio manipulation. Through fluid, multi-touch gestures inspired by modular synthesizers and the spirit of improvisation, you bend, shape, twist, and sculpt samples into rich, textured arrangements — sample putty you mold live, not just trigger. Whether you're playing live, jamming on the go, or exploring new sounds, Samposium turns your iPad or iPhone into an interactive musical instrument, welcoming to complete beginners and seasoned musicians alike. New in this release: Sequences just leveled up into Patterns. Build and edit up to 8 patterns (A–H) live, without ever stopping playback, so a simple loop can grow into a full arrangement without you ever losing the moment. Grab a Bluetooth MIDI controller and take hands-on control — every mapping in your project now lives in one screen, so you always know exactly what's wired to what.
