The S-4 is a sculpting sampler designed to capture and transform sounds. Merging tape-era workflows with cutting-edge technology, the S-4 redefines sound mangling by providing a futuristic platform for crafting unique soundscapes and compositions, using samples and real-time audio processing.

Create global macros to control multiple parameters at once. Map any parameter to eight performance knobs and four punch-in effect buttons for expressive changes with a single gesture.

Save and instantly launch parameter and sample snapshots. Capture full machine states, build variations, and swap samples on the fly — with up to 128 scenes per project, controllable on-device or via MIDI Program Change.

Temp brings performance functionality with temporary control of all parameters. When temp is enabled, S-4 saves the initial state and snaps back instantly when released.

A new playback device that streams audio directly from internal storage. Perfect for long loops, stems, and field recordings, limited only by storage capacity. A new modulation source: an envelope follower that uses track output or input signals to modulate parameters in real time.
