I created a Factory Set of all patches for the Roland D-20. I’m no longer a D-20 owner, but I had one for quite a long time, and have learned a lot about keeping one working and functioning as you can see in the archived posts related to it.
The downloadable SysEx file is the original factory sounds and settings for the D-20 from Roland. A lot of users lose these when they reinstall batteries or have a freeze or any problem. Sometimes people also tweak the sounds so much they lost the originals and are unable to get them back to where they used to be. Please note that you will need some sort of SysEx or MIDI library program to get the patches from your computer to the synthesizer.
Proteus 2500 Command Station
I also have a PDF copy of the E-Mu Proteus 2500 Command Station manual available. This is the synthesizer that I use, in addition to the soft synths in Logic Pro. The manual isn’t impossible to find, but it’s not out in plain sight on the web, either. I decided to put a link to it here to make it a little easier to find.
