How to Upgrade an Older Disklavier

DKC-850 RemoteIn most cases, it is possible to upgrade an older Disklavier with modern features, including internal memory, USB for MIDI, USB flash drive support, internal tone generator, CD drive, remote access with an iPhone, iPod touch or iPad, and even DisklavierRadio™ and DisklavierTV™ in most cases.

The upgrade is a new control unit called the DKC-850. In most cases, it replaces an existing control unit. In other cases, it functions as a piggyback control unit that connects to the old unit with MIDI cables.

The DKC-850 package comes with all the cables that you need and detailed instructions, including pictures for how to connect everything. Anyone can install the upgrade. A technician is not required.

There are a few important things to note about the upgrade:

• It is generally a good idea to have your Disklavier technician update your instrument to the latest firmware prior to installing the DKC-850. To obtain firmware updates and for information pertaining to previous generation Disklaviers, please contact Yamaha Piano Service:

This is also something you can do yourself.

• The DKC-850 upgrade does not change the characteristics of the built-in record and playback system. But it does give you modern features for interacting with your existing recording/playback system.

• Disklavier Radio and DisklavierTV are only available when the DKC- 850 is used as a replacement control unit. See the charts below.

• When used with a Disklavier PRO, the DKC-850 does not record or playback high resolution XP data that is normally recorded by a PRO. But it does play the normal MIDI data contained in an XP file, and it plays this data with exceptional refinement.
