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.

The internal memory battery has expired. Hopefully you have a memory card or sound disk about. Until you replace the battery, this will be what you experience upon powering up.

After a 10 year break I've dusted off my D20 for a one off gig. I remember all the A and B bank of sounds to be across the whole of the keyboard ie one sound per bank number.
However, now all of the sounds are split at C4 and I can't find some of the sounds I used to have.
Can anyone help here please?

I bought my D20 back in 1990 in Clermont Ferrand (France) because my Juno 106 and MS20 just weren't enough and I could not afford a D50. I was very happy with it for many years and even made my first steps in sequencing on it. But after I bought a D50 a few years ago, the D20 became redundant in my studio. Anyhow, today it still is a good synth in my 'remote' studio in my second house. Yes, it sounds thin now, but it is multitimbral, and a fairly good master keyboard.

Hey there,
I'm fairly new to the D-20 and I'm just now gettng back into playing after a good 20 year break. Something od I'm running ito is when I have the D-20 hooked up to he computer I'm only getting a Monophonic signal. Everything I'm readng sayd the D-20 should default to Midi Mode 3 Polyphonic. I was wondering if anyone else has run into this and if there was an easy fix for it. I apologize if this is something that should be very easy to figure out, like I said I'm just now getting back into it and I'm fairly sure I should be able to play a chord through midi to the computer.
