APS NoteCast is designed to allow you to stream directly to your Yamaha Disklavier, PianoDisc, QRS System, or other instrument. It lets you send MIDI files from an Android phone or tablet to devices such as a Yamaha Disklavier, player piano, digital piano, or keyboard, using Bluetooth MIDI adapters or USB MIDI connections.

Which adapter do I need?
Choose based on the connections on your piano or player system.
Round 5-pin MIDI IN and MIDI OUT
Common on Yamaha Disklaviers, PianoDisc and QRS systems, and many older digital pianos and keyboards.
Use: CME WIDI Master
If WIDI Master does not power on, use a CME WIDI Jack instead; it can be powered separately by USB-C.
Square USB-B port labeled USB TO HOST
Common on newer Yamaha Clavinova, CVP, Arius and P-series instruments and many other modern digital pianos.
Use: CME WIDI Uhost
You may also need the USB-B cable pack.
USB TO DEVICE? That’s the flash-drive port, not the USB MIDI connection described here.
How to connect APS NoteCast
First-time setup
- Connect the adapter and turn on the piano.
- Turn on Bluetooth on the Android device.
- Open APS NoteCast and allow Bluetooth or Nearby Devices access.
- Open MIDI connection, tap Scan, then tap Connect.
- If Android asks to pair, accept the pairing request.
- Confirm the adapter shows as Connected.
Test before real use
- Select a demo song or import a MIDI file.
- Start with the volume low.
- Tap Play and confirm the piano responds correctly.
- Tap Stop and make sure notes and pedals release.
- If anything hangs, tap Panic.
Safety note: A player piano moves real keys and pedals. Before using a long playlist or unattended playback, confirm that Play, Stop, and Panic all behave correctly while you are standing beside the instrument.
Need MIDI files?
APS NoteCast works with standard MIDI files. If you have Yamaha E-SEQ files
such as .FIL or .MDA, convert them first.
APS NoteCast is now available for public download on the Google Play Store!
Alternatives to Google Play?
The app is currently available as a separate APK, which can be side-loaded. You can download the APK from GitHub directly here. However, your testing in the Google Play ecosystem is very helpful to me, so please do consider downloading the app as part of an official test program!
