An MP ControllerByte device is a specialised touch monitor with analogue controls used with DAW applications and plugins.
The UPDD driver can offer additional touch functionality to that offered by default drivers.
The driver is available for Windows and macOS, delivered as .exe or .dmg files respectively.
You simply run the installation files and follow the instructions.
With macOS security considerations, during install you must grant permission to UPDD Commander to allow access to the system and, since macOS 10.13, manually 'Allow' our software to install in Security and Privacy section.
In multi-monitor environments, you may need to make the association between the touch screen and the MP Midi device by running the UPDD Identify procedure.
For specific installation instructions, please refer to the macOS and Windows Quick Installation Guides.
