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.

What’s New

Version 5.0.1

We're excited to bring auto-calibration to most SilentDrive settings! While we still recommend that technicians review and refine the results, the new auto calibration makes PianoDisc setup easier than ever before. Please note that a quiet environment is required to achieve optimal results.

This version includes the following changes:

- Auto calibration for most SilentDrive settings
- Noise gate support (for 2021 Prodigy CPUs)
- System information feature
- Improved MIDI connectivity

Goodbye Thumbwheel!

The iQ thumbwheel/blinking light interface seemed about as up to date as a punched paper roll or pumping pedals to make the piano play. The PianoDisc Calibrate app brings adjusting the iQ into the 21st century. The app is accessible either via a wired interface or a wireless one. You can jump straight to a note you want to calibrate on a virtual keyboard rather than umpteen flicks of your thumb on that doggone wheel. And on a new or appropriately updated CPU you can easily upgrade the iQ firmware. This is the greatest thing for the PianoDisc player since they got rid of the floppy disks and CD-ROM drives. One day I hope they might come up with a way to allow the iOS device to “listen” to the piano and calibrate each note on it’s own rather than rely on my subjective ear. But in the meantime, this GREATLY simplifies life for the appropriately trained installer you would otherwise be forced to use the iQ thumbwheel for calibration.
