Roland D-20

Roland D-20 Image

The D-20 makes a great budget or alternative D-50. It's more closely related to the D-10 and D-110 synthesizers but adds an 8-voice sequencer with a rhythm track. The D-20 is a digital synth that employs linear arithmetic synthesis (LAS). It's a confusing synthesis / editing method composed of tones, partials and timbres. Basically it all boils down to tricky programming which, if you know what your doing, can have interesting and unique results. Reverb effects and internal / external memory storage are also available on the D-20. Definitely worth a listen.

Johannes - I have a Roland D-20 and would consider selling it. It's barely been used - locked up in storage over the years. What's our next step???

peace to all ~

If there is someone you know who sell Roland D-20 please let me know. Mine was stolen in 2004 and I have been hunting for one around and I can't seem to be lucky. I am here in South Africa and I prefer if international people can use eBay, Paypal and let me know.

One Great Synth. A workstation for its day. I was deeply into my D-20. You were only limited by its polyphony. You made your own rhythm patterns and sounds. You set each volume of every drum and cymbal in your pattern. You set the pan on each one. You could raise or lower the pitch of you drums and cymbals. You could extend the time your cymbals rang. You produced with this synth. You could fatten sounds by adding partials or de-tuning a partial. You could mix sounds together for new sounds. You could edit sections of a track. Then quantize and save it. This is a testimony to what I know this synthesizer is capable of doing. Some of the posts about this synth make me laugh. The Roland D-20. One hell of a synthesizer.

Basic LA synth, i had one for a few years. Its a low cost D50 but it does sound ok. The synthesis is typical LA. it will not make fat sounds and the analog emulation is very old fashioned. The sequencer is very basic (no copy/editing/paste of sections of track). It records and deletes and thats about it!.
Any soft synth out shines this now sonically. but you have a synth and a bit of history.
At the time it was a poor man's Korg M1.
