Customers routinely ask me whether their Disklaviers can play MIDI, or only ESEQ, so I’m sharing this magnificent chart of Disklavier compatibility. This is sourced, originally, from Carol RPT’s Disk File chart, and I recommend visiting that website and seeing what they have to offer. They have a trove of information on older Disklaviers.

This table lists various Disklavier controllers and their corresponding floppy disk formats, recording capabilities, and playback options. Please contact me if you have anything to add to this Disklavier compatibility table, or if you see any inaccuracies. I do my best to confirm this against real world repair data.

For ease of use, equivalent piano models and controllers are grouped together.

And Now, The Table!

** Please see my page on determining whether your HQ100 or MX100II can play MIDI files. Earlier firmware cannot, although later firmware can.

Note that all later Disklaviers can play MIDI files, but after the Mark IV, support for ESEQ formats disappears. Accordingly, you’ll have to convert your ESEQ files to MIDI for modern systems such as the Enspire.

Note also that you cannot mix file formats on any Disklavier. If your disk or virtual disk contains ESEQ files, then it must contain only ESEQ files. Likewise, if it contains MIDI files, then it must contain only MIDI files, and no PIANODIR.FIL.
