If you're trying to connect your HP508 to an iOS device to use the free Roland apps, and the app isn't recognizing the piano, it may be due to the wrong USB driver setting. This can occur with both a wireless connection (using the WNA-1100RL), and a wired connection (using the apple camera connection kit and a USB A/B cable).
Please follow this procedure to set the USB Driver setting to the appropriate setting:
- While holding down the [Song balance] button, press the [AB repeat] button.
- Press the slow/fast arrows until you see "USB Driver" on the screen.
- Use the "+" and "-" buttons so that the setting "Generic" is selected (and not "original").
- Press the [Song Balance] button to exit function mode.
