The DKC100R is the controller used with DGPII and several related second-generation (Mark II) Disklaviers. It records and plays Yamaha’s older E-SEQ format from low-density (2DD) floppy disks; some units can also play Standard MIDI Files.

Things to Know
Some DKC100R systems may not support SMF0 playback; behavior may vary by firmware or model.
If replacing the floppy disk drive, use my Nalbantov model guide to find the proprietary slim drive that almost fits it. You’ll also need an insert so that the drive fits properly, which you can purchase directly from me.
Note that if a Nalbantov USB emulator is installed, a properly formatted USB stick must be left inserted in order to use Bluetooth MIDI, PianoStream, or other external MIDI devices.
You can use an external tone generator like the MU50 (or TG100) plus speakers. This allows you to play PianoSoft Plus floppy disks rather than only PianoSoft Solo, and adds some of the capability of the Mark II XG.
TG100- and MU50-targeted PianoSoft Plus titles are not completely interchangeable: the MU50 supports the broader XG title family, while the older TG100 does not provide full XG compatibility.
If this individual unit supports Standard MIDI Files but rejects a Type 1 file or plays only part of it, my free MIDI Type 1-to-Type 0 converter can create the single-track Type 0 copy these older controllers expect. It cannot add Standard MIDI support to an E-SEQ-only unit.
On this model, the documented DKC-850 path is a MIDI-cable add-on rather than a controller replacement, so it keeps the original controller and does not enable the DKC-850 online services. My Disklavier upgrade guide explains this path, and my DKC-800/850 power-adapter guide covers the external supply used by add-on installations.
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.
