The D50 Librarian is a library and real-time editor for the Roland D-50 and D-550 synthesizer that runs on the Microsoft Windows OS*.
*It can now also be run under emulation on Linux - See guide on "Requirements" page.
It features a library which can be used to store all your patches in one convenient place.
Patches can be transferred easily between the D50 Librarian and the D-50 / D-550 via MIDI.
Patches can be editted in real-time via one or two real-time editors including a virtual version of the PG-1000.
