The Torso Electronics S4 is a powerful, performance-focused stereo sampler built for sonic exploration and real-time sound transformation. Bridging the tactile creativity of tape-era workflows with modern digital processing, the S4 offers a unique platform for crafting evolving soundscapes, intricate compositions, and spontaneous performances. With its hands-on interface, deep modulation system, and newly upgraded OS 2.0, the S4 sets a new standard in hardware sampling. Features: Four Parallel Stereo Tracks: Each track runs an independent signal chain with samplers, granular processors, morphing resonators, and advanced effects. Extensive Modulation System: Up to 20 modulators per track including complex LFOs, envelopes, generative tools, and the new Follow device for envelope following based on audio amplitude. Live Sampling and Processing: Capture sounds via the stereo line input or built-in microphone, then instantly mangle, stretch, and transform them in real time. Disc Device: Stream long-form audio directly from internal storage with virtually unlimited sample length—ideal for full stems, field recordings, or extended loops. Enhanced Tape Workflow: The Tape engine now supports varispeed recording, loop overdubbing, and time warping for deeper performance capabilities. New in OS 2.0 Macro Controls: Map any parameter to one of eight performance knobs or four punch-in buttons for sweeping, expressive changes. Scene Management: Instantly switch between full project states or build live arrangements with up to 128 scenes per project, now MIDI-controllable. Temp Mode: Experiment freely during performance—when released, the system snaps back to its original state. Workflow Enhancements: Improved UI, copy/paste for tracks/devices/scenes, upgraded Tape device, and refined modulation routing. New Devices and Rewritten Engine: OS 2.0 introduces a complete engine overhaul for better performance and expanded creative capabilities.
