Yamaha Disklavier DSR1 Upgrade Compatibility Guide

All Disklavier Models

DSR1 is an upgrade unit for Mark I and Mark II Disklaviers that adds Mark II XG-style media and format support, including 1 MB internal flash memory.

Things to Know

The DSR1 is an upgrade unit that adds Mark II XG capabilities to the Marks I and II. It includes a 1 MB internal flash memory disk.

If replacing the floppy disk drive, purchase the Nalbantov, as they make a proprietary slim drive that fits it.

Recording and playing back E-SEQ is confirmed on Page 64 of the DSR1 owner’s manual.

This is not to be confused with the MU50 (or TG100). These tone generators could be added to the Mark I and Mark II era pianos and would add support for PianoSoft Plus floppies, but did not add new drives or support for SMF0.
