PianoDisc Calibrate is a companion app for automatic player pianos equipped with SilentDrive HD systems.  The app allows professional PianoDisc installers to calibrate key features and settings faster and easier than ever before.

PLEASE NOTE:  This app is designed to be used by professional installers who have completed the PianoDisc installation training program.  Improper adjustment is not covered under warranty, and may adversely affect playback.


A hardware MIDI interface is required (such as the Prodigy CPU, Roland UM-ONE Mk II, or Quicco Sound mi.1).  MIDI IN and OUT must both be connected to the SilentDrive HD CPU.

NOTE: The MIDI interface must be connected before you launch the app! Settings are only adjusted when the MIDI indicator is green. If the indicator remains red, try pressing the reset button on the SilentDrive CPU.
