The DKW10 is the external controller used with early first-generation (Mark I) Wagon and DGP Disklaviers. It records and plays Yamaha’s older E-SEQ song format from low-density (2DD) floppy disks and can be adapted for Bluetooth MIDI, CD playback, or external instrumental accompaniment.

Things to Know
I’ve found these require a floppy disk to be inserted in order to use Bluetooth MIDI, PianoStream, or other devices plugged into the MIDI ports. This can be bypassed by powering on the system while holding down the MIDI and REC buttons. See Why isn’t PianoStream Working? for more.
Noah Jolly at Ground Grown Circuits can make replacement cables for Wagon systems.
The Wagon Grand recorded 16 pedal positions; MX100A/B systems from the same broad era recorded pedal movement only as on/off data.
This controller cannot play an ordinary .mid file from its floppy drive. My APS MIDI Prep Tool floppy guide shows how to convert a MIDI file to E-SEQ and create the PIANODIR.FIL directory the Disklavier expects.
If a computer reports an original Yamaha Disklavier floppy as unformatted, do not format it. My Disklavier floppy-recovery guide explains why this happens, and my tested USB floppy-drive guide identifies hardware that can read 720 KB/2DD disks.
Nalbantov replacements are model-specific. My Nalbantov floppy-upgrade guide identifies the standard, slim, and dedicated versions; do not assume that a generic Gotek—or any Nalbantov—will fit.
