The Focusrite USB MIDI Windows Driver is a software package that enables communication between a Focusrite audio interface (or other Focusrite USB devices) and a Windows computer, specifically for handling MIDI (Musical Instrument Digital Interface) data. When you connect a Focusrite device to your computer, the driver allows MIDI data to be transmitted from the device to music software (DAW) and vice versa. Without this driver, your system may not properly recognize the device for MIDI input/output, or it may not function correctly with your DAW.
Focusrite devices typically use their USB drivers to facilitate both audio and MIDI functionality. For MIDI-specific operations, these drivers are crucial to ensuring that your Focusrite device communicates properly with MIDI instruments, controllers, or software on your Windows system.
