Roland D-20 Productivity Activities and Utilities

There a series of processes / productivity activities that will help you use the Roland D-20 in your studio or live environment.  

Given the age of this instruments (being released in 1988 and in production until 1992) I would not recomend you gig these in the current day.

Restoring the Roland D-20 using System Exclusive (SYSEX)

This video walks through the complete process of restoring factory sounds to a Roland D-20 using the SYSEX method, offering a practical alternative for owners who don't have access to a RAM card loaded with original presets. It covers where to find the correct patch file on Roland's official website, why the generic MID file often causes problems in MIDI-OX on Windows 10, and where to source a reliable SYSEX alternative instead. The tutorial is aimed at anyone looking to bring a Roland D-20 back to its factory sound set using nothing more than a basic MIDI interface and a laptop.

The video then details the hardware and software setup required before any file transfer can happen. A simple MIDIsport interface connects via USB to a Windows machine, with a standard five-pin MIDI cable running from the interface into the synthesiser's input socket. Configuring MIDI-OX correctly is shown to be just as important as the physical connections, with specific buffer settings, delay adjustments, and colour-coded SYSEX display options recommended for smooth results. Saving these settings as a profile makes future sessions with the Roland D-20 much quicker to set up.

Finally, the tutorial demonstrates preparing the synthesiser itself to receive the SYSEX dump, including the correct key combination for initialising the unit, setting the MIDI exclusive channel, and enabling one-way bulk loading while disabling memory protection. Once the file is loaded and sent from MIDI-OX, the transfer takes roughly thirty seconds to complete. The video closes with confirmation that the factory patches have been successfully restored, giving viewers a clear, tested workflow for reviving the original sounds on a Roland D-20.

Backing up the Roland D-20 using System Exclusive (SYSEX)

This video demonstrates how to back up the sound creations on a Roland D-20 synthesiser using the SYSEX method. While the instrument offers a few different backup options, including a RAM card for instant recall, floppy discs have become increasingly difficult to source nowadays, making SYSEX transfer the most practical and reliable approach for preserving custom patches created on the Roland D-20.

The video walks through the software and hardware set-up required before any data transfer can begin. MIDI-OX, a free tool for Windows, is favoured over Mac-based alternatives, paired with a MIDIsport interface for stable communication with the synthesiser. Specific configuration settings are covered in detail, including input and output values and the display of hexadecimal markers, which help visually identify where each data block begins and ends. These settings are especially important given that older instruments like the Roland D-20 transmit and receive data more slowly than modern equipment, so getting the configuration right helps avoid transfer errors.

Once the set-up is complete, the video demonstrates the full transfer process from start to finish. The computer is placed into listen mode, the synthesiser is set to send a full data dump, and the transfer itself completes in roughly fifteen seconds, moving around 43,000 bytes of data. Viewers can watch the process unfold in real time, including how to confirm the transfer has finished and how to save the resulting SYSEX file onto a computer or into a dedicated librarian for safekeeping. By the end of the video, viewers are left with a clear, repeatable method for archiving everything programmed into their Roland D-20, ensuring that custom sounds and settings remain safe even as original storage media becomes harder to maintain.
