Yamaha Disklavier DKC-850 Upgrade Compatibility Guide

Things to Know

Recordings are created in SMF0. E-SEQ support is playback-only. Can use the Yamaha UD-FD01 external floppy disk drive.

Requires updated firmware for Disklavier Radio and other online services.

Can be controlled with the Yamaha Disklavier Controller app (Apple only).

This system cannot necessarily be upgraded to the DKC-900. Only pianos that were originally E3 or Mark IV/Mark IV PRO systems are eligible.

Note that if the DKC-850 is attached to the Disklavier using MIDI cables (a so-called piggyback installation), it cannot be used for Internet Direct Connection, Disklavier Radio, or DisklavierTV. MIDI-cable add-on support covers supported Mark II DKC100R/built-in systems and Mark II playback DKC100XG; online services only work when the DKC-850 is installed as a replacement.

All USB sticks must be formatted FAT16 or FAT32. In my experience the DKC-850 also requires they not have partition tables; they should be formatted as superfloppies. See my guide on properly formatting your USB stick for use with Disklaviers.

Although Smart PianoSoft is supported, CD playback will instead be synced with files on a USB stick instead of floppy disks. PianoSoft Audio can be played either off of CD or USB stick. PianoSoft Solo and Plus files are still supported, these are downloaded and placed on a USB instead of using the original floppies.
