Here we have a vintage Roland D-550 rack mount linear synthesizer in excellent condition. The Roland D-550 is the official rackmount version of the legendary Roland D-50 synthesizer, packing the exact same groundbreaking Linear Arithmetic (LA) Synthesis engine into a keyboardless space-saving format. Celebrated for defining the late-1980s pop era and countless film scores, it excels at producing lush ethereal pads, shimmering bells, and punchy digital textures.

Core Synthesis & Architecture

• Linear Arithmetic (LA) Synthesis: Combines short, 8-bit PCM sampled attack transients (like a trumpet breath or a bell strike) with traditional, digitally generated subtractive synthesis for the sustaining tail.
• Voice Polyphony: Features 16-voice polyphony in whole mode, which drops to 8-voice polyphony when layering two distinct tones (Upper and Lower partials) in Split or Dual mode.
• Onboard Signal Path: Each non-PCM wave passes through a resonant digital low-pass filter—the Time Variant Filter (TVF)—and a Time Variant Amplifier (TVA) accompanied by flexible envelopes and 3 LFOs per voice.
• Cosmetically: The unit has a few scratches (pictured), but is in excellent condition.
• Ships fast and insured.

Unit weighs 16 lbs.

Visit out website to see the long list of celebrity musicians and groups we have met and serviced in the past 40 years. 

NOTE: Too cool. We just shipped very recently this summer a 1967 MapleGlo Rickenbacker 6-12 Converter 'comb' guitar to Billy Corigan of Smashing Pumpkins! We also then shipped a vintage 50 watt Marshall head to L.A. studio-touring guitarist extraodinaire, Michael Landau, and 2 vintage guitars to Jack White's organization down in Nashville just a few days before his 50th. birthday! mmm? Add 'The Kentucky Head Hunters' to the list, just sold Greg a cool little 50's Valco tube combo amp!

Gordy's Music has become a Detroit institution! Our shop was used as a filming location for a few films like "Miracle in Motor City" a Christmas movie on Lifetime (featuring Smoky Robinson). We've supplied gear for movies including "Bill & Ted Face The Music" with Keanu Reeves. We've got decades of celebrity customers, including recent visits from Beck, Eric Johnson, and we recently sold Billy Joel's bassist a cool Gibson SG he is in love with. One day a while back Andre 3000 and his group stopped in to browse as they were playing Masonic Temple that night and right after that we sold an old oil can Morley Wah Vibrato pedal to Credence Clearwater Revival's thee John Fogerty!

We are having and have had a lot of fun here at Gordy's Music! I was just remembering about 35 years ago a tour bus pulled up to our little shop, and who rolls right in and hangs out for an hour? Lenny Kravitz and his entire group, right about the same time I was selling many guitars to and chauffeuring around Dee Dee Ramone who had an apartment a block down from my house.
