The Roland S-550 is a powerful 12-bit rackmount sampler that built on the foundation of the S-50, introducing enhanced hardware features, an expanded memory capacity, and real-time control that made it a standout in late-'80s sampling technology. With 16-voice polyphony, multitimbral performance, and the ability to load and manipulate samples via mouse and external CRT monitor, the S-550 remains a cult classic for producers who love hands-on sampling and hardware workflow.   It offers 8 individual outputs, time-variant filters with resonance, and a flexible voice assignment system all wrapped in a system thatÕs still surprisingly intuitive with the right monitor and mouse setup. Additional features include sample mixing, truncating, crossfade looping, and graphical waveform editing. The S-550 also introduced the ability to process and preview real-time memory sampling with a pre-buffer making it easier to capture audio on the fly.   This pre-owned unit is fully tested and in good working order. It's ideal for anyone seeking that gritty, characterful sampling sound of the late '80s and early '90s especially fans of hardware-based editing and sequencing.   Key Features
