Torso Electronics S-4 White

Torso Electronics S4 White Special Edition – a sculpting sampler that merges the tactile charm of tape-era workflows with modern digital precision. This limited-edition version features a cream-white aluminum enclosure, custom gray knobs, and a matching white display theme (switchable to black). It delivers the same deep creative power as the standard S4, now wrapped in a refined and minimalist design that perfectly complements studio and stage setups.

The S4 is designed to capture, transform, and reimagine sound. Each of its four stereo tracks includes a five-stage signal chain – Material, Granular, Filter, Color, and Space – enabling the creation of complex textures, cinematic soundscapes, and evolving rhythmic structures. Record and overdub directly, use the 8-voice polyphonic sampler via MIDI, or sculpt live audio through granular synthesis, morphing filters, and dual-band distortion. The powerful modulation system provides four modulators per track, allowing any parameter to be animated with LFOs, envelopes, random generators, or sequencers, including cross-modulation possibilities for intricate motion and depth.

Equipped with tactile RGB buttons, a 3.5-inch color LCD, and nine smooth encoders, the S4 offers an intuitive interface for deep sound design and live performance. It can function as a standalone instrument, an advanced effects processor, or a USB audio interface (10 in / 10 out) for DAW integration. Whether used as a live looper, tape machine, or textural synthesizer, the S4 White Special Edition invites exploration and sonic experimentation in a beautifully redesigned package.
