Roland D-50 / D-550

Roland D-50 Image

The D-50 is an all-time favorite digital synth that's still just as popular today as when it first came out in '87. Once Roland's hottest digital synth, it competed against the Yamaha DX7, and was much easier to use. By joining 8-bit PCM samples with "LAS" synth-generated sounds, the D-50 is capable of unique and complex sounds. The PCM samples contained the attack transients, while the rest of the sound came from the Linear Arithmatic Synth (LAS) section which sounds very analog, with subtractive-style synthesis and low-pass-resonant filters. Built-in chorus and (for the first time) digital reverb are also included for giving your sounds space and life! It also has a joystick controller for real-time timbre manipulation. The D-50 was great for new and non-acoustic, percussive, ethereal and beautiful pads & sounds.

Roland D-550 Rack Version

Both the D-50 and D-550 benefit from the PG-1000 external controller which gives you very plain and simple slider/fader type control of all adjustable parameters of the synth. The D-50 includes MIDI on all 16 channels but because it is monotimbral you can only use one channel at a time. There is an upgrade which will give the D-50 and its rackmount version a full 16 channels of simultaneous MIDI multitimbral data communication. This popular synth has been widely used in all forms of music. Eric Clapton, Enya, 808 State, Jean Michel Jarre, Vince Clarke, Apollo 440, Eat Static, LTJ Bukem, Fluke, Information Society, Lab-4, Gary Numan, Rick Wakeman, Kitaro, Rush, Vangelis, Richard Barbieri, Boston and Nick Rhodes of Duran Duran are just a few of the many satisfied users.

My first real synth (got it back in the early 90s), lead to my current synth obsession. First all-digital synth from Roland, and was a massive hit back in the day. LA synthesis consist of pretty limited PCM playback (short, poor samples that cannot be filtered), but then there is an awesome proto-analog modelling section that was probably not bettered until the 2nd or 3rd generation of analog modeling synths hit the market. Even then, it has a sound of its own, some aliasing etc that can actually sound pretty cool IMHO. I still have a D-550, and still love some of the signature sounds.

The ROM cards have extra/new Reverb Types (17-32)
which can be copied from the ROM card and saved inside patches…
Just wondering if it's possible to edit those reverbs? Make yer own??
Anybody know about that?

I have owned my D-50 since it's release. The joystick does not spring into the center position. It was not designed to do so. Awesome keyboard even to this day. LOVE IT..

luke......the d50's joystick does not have a spring.....or at least mine doesn't anyway!
the joystick remains in the last used position.
if you do buy a d50....download chris nightingales d50 editior, it's free and works in the same way as pg1000 and acts as a library for d50 sounds.

I'm interested in buying a D-50, but I have a question I'm hoping someone here can answer -- does the joystick have a spring? As in, does the joystick naturally return to the center when it's not in use? I've been looking at eBay listings, and I'm not sure if some of the joysticks I'm seeing are broken, or if the joystick remains in its last used position. Thanks for the help!
