DKC-900 / ENSPIRE is the current USB-based Disklavier system, supporting SMF0, SMF1, WAV, and MP3 playback, with recording limited to ENSPIRE ST/PRO and DKC-900 upgrades.
Things to Know
ENSPIRE CL = playback-only (no recording). ENSPIRE ST/PRO and DKC-900 upgrades support recording. The DKC-900 upgrade is limited to eligible E3 and Mark IV/Mark IV PRO systems; it is not a Mark III-or-older upgrade path.
Can be controlled with the ENSPIRE Controller app, available for both Apple and Android devices.
All USB sticks must be formatted FAT16 or FAT32. See my guide on properly formatting your USB stick for use with Disklaviers.
Although this is not documented anywhere, the ENSPIRE / DKC-900 currently seems to have an overall song limit. A technician at Yamaha informed me that they recommend having no more than 1000 songs on a USB stick, and never using a 128GB or larger USB stick. There are reports of USB sticks with several thousand songs causing system hangs, UI glitches, and other problems.
Without a CD player, Smart PianoSoft is no longer available. PianoSoft Solo, Plus, and Audio files are still supported, but are played off of USB.
