A Mark IV Disklavier divides its controls among a DMC-100 Media Center, DIO-100 I/O Center, and PRC-100 Pocket Controller. It plays music from internal storage, USB drives, CDs, or floppy disks and records MIDI performances plus, with firmware 3.0 or later, digital audio. Eligible systems can be upgraded with a DKC-900.

Additional Details
This generation uses a separate DMC-100 Media Center, DIO-100 I/O Center, and PRC-100 Pocket Controller.
The DMC-100 provides the CD/floppy drives and controls; the 80 GB hard drive is inside the DIO-100 I/O Center and is an important part to check on an older Mark IV.
Things to Know
WAV audio recording and playback require Mark IV firmware 3.0 or later. E-SEQ supports playback and overwrite recording rather than ordinary creation of a new E-SEQ song.
Requires updated firmware for Disklavier Radio and other online services.
The 80 GB hard disk is a common point of failure and can be replaced, but an SSD conversion is not a generic drop-in swap. Successful replacements normally use a whole-disk/sector clone and compatible PATA/IDE hardware or adapter; some adapters and partition-only clones will not boot.
Mark IV can record piano MIDI plus 44.1-kHz/16-bit stereo WAV audio simultaneously. PRO pianos also embed high-resolution XP performance data in the MIDI file; stripping XP is irreversible.
This system is eligible to be upgraded to the DKC-900. See my generation-by-generation Disklavier upgrade guide for the supported path.
Can be controlled with the Yamaha Disklavier Controller app (Apple only), or from a computer using the Virtual PRC.
dkvBrowser is a third-party Java project for controlling and managing Mark IV Disklaviers from a computer, and may be a practical alternative when the PRC-100 Pocket Controller is missing or difficult to use.
USB flash drives may use FAT16 or FAT32; USB hard disks must use FAT32. See my guide on properly formatting USB media for Disklaviers.
The system remembers identifiers for only seven otherwise identical USB memories. If an additional identical device is not recognized, shut the Mark IV down before exchanging it.
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.
