Passthrough Devices

Certain instrument controllers require direct access to the emulator, which call for additional setup.
If you were sent here, chances are you will need to follow these steps for your instrument to work.

Please note that you will need to repeat this process three times for each mode [D,K,G] on the MIDI PRO Adapter!
After making sure you have the correct dongle or MIDI PRO Adapter, close out RPCS3 and plug in the instrument’s dongle or MIDI PRO Adapter to your computer.

  1. First, [go to Zadig’s website] and download the latest version, then open it up.

  2. Click on Options then List All Devices.

    Zadig showing 'List All Devices' under 'Options' highlighted.
  3. You should now see devices listed. Switch it to your Rock Band 3 Pro Instrument.
    In this example, we’re using the Mustang Pro Guitar, which shows up as Harmonix RB3 Mustang Guitar for PlayStation® 3.

    Click Replace Driver.

  5. A warning will appear.
    Again, make sure you have selected your RB3 Pro instrument’s receiver or adapter.
    After you have made sure, click Yes.

  6. It will then install the driver. As the program says, it may take a few minutes.

  8. Close Zadig.

  9. Open up Rock Band 3 in RPCS3 and connect your controller.
    You should see it automatically assign a player number.

Applying a Zadig driver on a device will make it only work on applications with passthrough. This may cause issues with Clone Hero or YARG.
Thankfully, reverting this is very easy!

  1. Open the Start menu and search for Device Manager. Open it.

    Windows' Start menu, with a result of 'Device Manager'.
  2. Scroll down until you find the Universal Serial Bus devices category.
    Expand it and right click the instrument you applied the Zadig driver on and then select Uninstall device.
    In this example, it’s the Pro Guitar (Harmonix RB3 Mustang Guitar for PlayStation® 3).
