Roland D-550 Synthesizer Module
Introduced in the late 1980s, the D-550 is a classic digital synthesizer module built around Roland’s proprietary Linear Arithmetic synthesis engine, offering 16-voice polyphony for complex, evolving sounds. Its extensive sound range spans rich pads, classic synth leads, and unique sound effects, shaped in real time by onboard filters, envelopes, and LFOs. Built-in digital effects — reverb, delay, and chorus — add depth to every patch, and a built-in arpeggiator makes it easy to create complex patterns and sequences. A large LCD display with knobs and sliders gives hands-on control, while full MIDI support allows seamless integration with other MIDI-compatible instruments and devices.
