About this app

-----------------------------------------------------------------------
During testing of Song Bank Plus on devices running Android 13,
a bug has been found where some functions do not work correctly under Bluetooth MIDI connection (*).

This bug only occurs on Android 13.

* On Google Pixel series (excluding Pixel 4/4 XL), this issue has been confirmed to be resolved with the March 2023 monthly update.

* For other smart devices, the update status varies depending on the manufacturer and device. Please contact the manufacturer or carrier for compatibility information.

We sincerely apologize, but please refrain from using Song Bank Plus on Android 13 until the issue is resolved.

This issue does not occur when connected via USB cable or when connected to devices running Android OS up to Android 12.

(*) Using a wireless MIDI & AUDIO adapter (our WU-BT10).

-----------------------------------------------------------------------

*For users of the Wireless MIDI & AUDIO Adapter (WU-BT10) and MIDI player, your smart device must be running Android OS 8.0 or later and support Bluetooth® Low Energy.

*Smart devices that display a MIDI-incompatible alert during app installation cannot connect to the instrument.


*1 If the app does not start correctly, please try either A or B below.
A. Delete the app data and cache by going to Device Settings > Apps > Song Bank Plus > Storage > Clear Data, then launch the app.
B. Uninstall Song Bank Plus, then in Device Settings > Google > Backup > Back to Google Drive (turn OFF), reinstall the app.

*2 When installing this app for the first time, please check if the message "Your device does not support MIDI" appears. If this message appears, your device is not USB-MIDI compatible.

*3 Please note that the built-in songs for the LK-550, LK-540, LK-530, LK-520, LK-515, LK-512, and LK-511 within the app cannot be transferred to the LK-550, LK-540, LK-530, LK-520, LK-515, LK-512, LK-511, LK-516, LK-526, or LK-536 units.

*4 We have confirmed that some SHARP devices may not function correctly with MIDI connection-related features. This issue may be resolved by updating the device's firmware to the latest version; please check your firmware version. For further details, please contact SHARP or your mobile carrier.

◆ Expand your song library by connecting to a smart device
You can transfer song data downloaded and purchased from "Song Bank Plus" to the LK-550/LK-540/LK-530/LK-520/LK-515/LK-512/LK-511/LK-516/LK-526/LK-536 keyboard. You can add your favorite songs in addition to the built-in songs.

● What you need for connection and how to connect
For detailed connection information, please see the connection diagram.
https://web.casio.com/app/ja/songbankplus/support/connect.html

*To transfer song data from your smart device to the keyboard, please use the included audio cable or a commercially available USB cable (A-B type or C-B type). A USB cable allows for faster transfer, but an A-B type USB cable requires a USB-OTG cable (USB conversion adapter). (Audio cable included only with LK-550/LK-540/LK-530/LK-520/LK-515/LK-512/LK-511)
*Please set your connected smart device to airplane mode or disable mobile data communication.
*Do not connect the USB cable and audio cable to your smart device simultaneously.

"Song Bank Plus" offers a diverse lineup of songs, including hit songs from both Western and Japanese music, and piano pieces. There are two display modes.

◆Enjoy a game-like experience with Melody Master
By using a commercially available USB cable, the LK-550/LK-540/LK-530/LK-520/LK-515/LK-512/LK-511/LK-516/LK-526/LK-536 unit and the app screen will synchronize, allowing you to enjoy Melody Master, a game-like experience.

Using the optional Wireless MIDI & AUDIO Adapter (WU-BT10), you can enjoy Melody Master, a game-like experience where the keyboard (LK-550/LK-540/LK-530/LK-520/LK-526/LK-536) and the app screen are wirelessly linked.

*Note*
With Bluetooth® connection, depending on the communication environment and the performance of your smart device, you may notice noticeable sound delay or distortion in the app's lesson function. In such cases, please try the following:
- Check the app's instruction manual for how to use the lessons and MIDI playback quality.
- Connect using a cable.

● Play along with the piano roll falling from above. Challenge yourself to get a PERFECT!

● Scoring function to track your progress

● Recording function to listen to your own performance

*Melody Master, scoring function, and recording function can also be enjoyed using only your smart device.

★Operating Requirements (Information as of November 2022)

Android 6.0 or later
Recommended RAM size: 2GB or more
*When using a USB cable (A-B type or C-B type) connected to a compatible keyboard, an OTG/MIDI compatible device is required. (Some devices may not be compatible.) If using an A-B type USB cable, a USB-OTG cable (USB conversion adapter) is required.

Please use an OTG/MIDI compatible device when using the following functions:

* Song transfer via USB cable

* Melody Master linked to the keyboard (including Step-Up Lesson/Scoring/Recording function)

We recommend using the following devices, and we do not guarantee operation on devices not listed.

We will continue to add devices that have been confirmed to work to the list of compatible devices as they become available.

Even with compatible devices, correct display and operation may occur due to device software updates, Android OS version updates, etc.

Devices using x86-based CPUs are not supported.
