Below are a couple of things to make sure that you have tried.
- Verify that Bluetooth is enabled on your H9. A blue LED in the upper right-hand corner of the H9’s display will be lit up if Bluetooth is turned on. Turn Bluetooth off and on again on the H9 to reset the state of the Bluetooth chip by pressing the X, Y, and Z buttons on the H9 simultaneously.
- Make sure you are using the Eventide power supply.
- Make sure have tried one of the two factory resets below:
Restoring Factory System Settings
To restore System settings, power up the H9 while simultaneously pressing the Right Footswitch and the HOTKNOB button until [CLEAR] is displayed.
Restoring Factory Presets and System Settings
CAUTION: This function will overwrite any Presets that you have saved. To restore Factory Presets and all System settings, power up the H9 while simultaneously pressing the Right Footswitch and the big Knob until [INITIA] is displayed.
Make sure you have completely powered off your device (iOS or computer) and then powered it back on again.
If using a mobile device, reset the network settings.
