The DigiTech BP355 MIDI driver enables Windows to recognize and communicate with the MIDI interface of your BP355 bass multi-effects processor. This Harman International device needs the appropriate driver for compatible software to exchange MIDI data with the hardware; choose a package that matches your version of Windows 11, 10, 8, or 7.

Key Features

• MIDI device recognition: Helps Windows identify the BP355’s MIDI interface so compatible applications can access it.
• Software communication: Provides the connection needed for supported MIDI messages to pass between the processor and your computer.
• Application integration: Allows MIDI-capable music software or compatible device utilities to use the BP355 interface once it is selected in the application’s settings.
• Dedicated MIDI support: Addresses MIDI communication specifically. Audio recording and playback may require separate driver components or settings, depending on the package.

How to Install

1. Check your Windows configuration. Confirm whether you are using Windows 11, 10, 8, or 7, and check your system architecture. Review the download’s compatibility information before installing, especially on newer Windows versions.

1. Download and prepare the driver. Choose the DigiTech BP355 MIDI driver package intended for your system. Extract the files if they are supplied in a compressed archive, and read any included installation instructions.

1. Run the installer. Close music applications, launch the setup program, and approve the Windows permission prompt if requested. Follow the package instructions about when to connect or disconnect the BP355.

1. Connect the processor. Power on the BP355 and connect it directly to a USB port on your computer when instructed. Let Windows finish configuring the device, then restart if the installer requests it.

1. Verify MIDI access. Check Device Manager for device warnings, then open your compatible music application and select the BP355 in its MIDI settings. If it does not appear, try another USB port and confirm that the installed package supports your Windows version.

Common Issues and Fixes

• Install fails or rolls back: Run the BP355 driver installer as Administrator, disconnect the pedal until prompted, and reboot before retrying. If using an older unsigned package, temporarily disable Windows driver signature enforcement.
• Device not detected: Use a USB 2.0 port and a known data cable, not a charge-only cable. Avoid unpowered hubs. Check Device Manager for an unknown USB/MIDI device, then reinstall and reconnect the BP355.
• Version conflicts: Uninstall older DigiTech/Harman USB MIDI drivers and remove hidden devices in Device Manager. Reboot, install the current BP355 driver first, then connect the pedal. Rescan MIDI devices in your DAW and select the BP355 entry.
