DISKLAVIER (or “DKV”)
A typical Disklavier consists of the following three units.
• Control Unit: Includes control panel, FDD (floppy-disk drive), flash memory, CD drive, etc.
• Sensor Unit: Detects performance actions.
• Drive Unit: Drives keyboard and pedals during playback.
These units communicate with one another through the PK-CTL sheet (Pedal/Keyboard Control sheet).
