    What to do if the RockJam Controller doesn't respond in the tablet app?

      If the app on your tablet isn't responding to key presses on the RockJam Controller, try exiting or force-closing the app. Then, restart the app and re-establish the MIDI connection, either through the app's Bluetooth settings or with a wired connection.

      If your RockJam Controller is behaving erratically or its output is intermittent, it might be due to a low internal battery. Please recharge the device for about an hour to restore consistent operation.

    Why can't I connect RockJam Controller via Bluetooth in my device's settings?

      Bluetooth MIDI connection for the RockJam Controller needs to be made from within an app that supports Bluetooth MIDI, such as ‘Garageband’. It cannot be established directly from your device's Bluetooth settings.

    What to do if sustain pedal doesn't work with RockJam Controller?

      If the RockJam Controller isn't responding correctly to the sustain pedal input, it might be because the sustain pedal was plugged in while the MIDI controller was already switched on. To fix this, power off the MIDI controller, disconnect and reconnect the sustain pedal, and then power the MIDI controller back on.

    Why isn't my hardware synthesiser responding to key presses on the RockJam Controller?

      Jasmine HarrisonAug 30, 2025
      If your hardware synthesizer isn't responding to key presses on the RockJam Controller, the cause might be an incorrect MIDI cable. Ensure that the MIDI cable you're using is the correct type for your synthesizer, as there are two connection standards: type A and type B.
