Up for sale is a legendary piece of synth history: a Roland D-550 Linear Synthesizer 2U rackmount module.
Built in Japan, this is the exact rackmount counterpart to the iconic 1987 Roland D-50 keyboard. It features the identical, coveted Linear Arithmetic (LA) Synthesis engine that defined the sound of late-80s pop, cinematic soundscapes, and early 90s dance music. From glass voices and digital chimes to fat, lush ambient pads, this unit has incredible character that software emulations still struggle to fully replicate.
