Yamaha Disklavier MX100II Compatibility Guide

All Disklavier Models

MX100II is a Mark II built-in system that records E-SEQ, plays E-SEQ and sometimes SMF0, and can be expanded with PianoStream, DCD-1, MU50/TG100, or DKC-850 paths.

Things to Know

I’ve encountered MX100II that do not support SMF0 playback. There does appear to be some disagreement, and I have an article based on a Japanese-language website on determining if your MX100II / MPX100II / HQ100 supports MIDI playback.

If replacing the floppy disk drive, purchase the Nalbantov, as they make a proprietary slim drive that almost fits it. You’ll also need an insert so that the drive fits properly. I include a 3D model in that article, which is freely available.

Note that if a Nalbantov USB emulator is installed, a properly formatted USB stick must be left inserted in order to use 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. If using both the MU50 and a Bluetooth-MIDI device, see my article on using the U4MIDI to add multiple MIDI devices to your Disklavier.

Not to be confused with the similarly named MX100B.
