It gives you control over how audio is sliced, mapped, and played, so you can turn raw material into something musical.

The Sampler also helps you easily create advanced rhythms - use note repeat to create rolls, patterns, and rhythmic variations in real time. Layer multiple samples to build depth and texture. Effects are built in. Shape your sound with tools like EQ, compression, delay, reverb, distortion, and more. Apply them directly and hear the result instantly. This lets you move from raw audio to a polished sound without leaving the app. Recording is part of the workflow. Capture your performance, layer ideas, and build something more complete over time.
