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 you are 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.

Cheers

I am posting this here not only for fellow D-20 owners, but also for myself. I just found an incredible website ( that has a bunch of stuff for the D-20. I know, [beep] , right? This thankless individual obviously spent some time and effort finding and documenting various utilities and patches for this seldom-loved keyboard. CHECK THIS ( OUT: Steinberg actually made a synth editor for this thing back in 1988 for the Atari ST! You can run it in an emulator! I trust many D-20 owners will be interested.

Is the programmer worth having - i.e. does it make programming substantially easier?
