The Crystal WDM MPU-401 Compatible driver refers to a Windows driver for sound cards or audio interfaces that are based on the Crystal Semiconductor WDM (Windows Driver Model) MPU-401 interface. The MPU-401 is a hardware standard originally designed for MIDI (Musical Instrument Digital Interface) communication. Many sound cards or audio interfaces use the MPU-401 interface for MIDI device communication.
WDM (Windows Driver Model) is a driver architecture for Windows operating systems, ensuring that hardware devices (like the MPU-401-compatible sound cards) work with the operating system and software applications. The Crystal Semiconductor brand was one of the prominent developers of audio solutions, and their sound chips, especially those in the Crystal Sound series, were often used in budget and mainstream PCs in the late 1990s and early 2000s.
