The Windows Sound System hardware does not meet all of the requirements toqualify for the Multimedia PC Marketing Council, Inc. (MPC) logo. However,if Windows Sound System is installed on a computer that includes thefollowing from other cards, the system is considered MPC compliant:

  • a Musical Instrument Digital Interface (MIDI)
  • a small computer system interface (SCSI)
  • a joystick port
The MPC designation applies to a complete computer system or to afull upgrade kit. The Windows Sound System is an audio card, which is onecomponent of an MPC-compatible system. You need to add the other componentsto have your system qualify as an MPC system.

MIDI, SCSI, and joystick ports were omitted from the Windows SoundSystem because most users do not require these components.

Alternative means of supplying this functionality are described below.


Almost all CD-ROM drives have a SCSI interface card. If you installthis card, you must use an additional slot on your computer that youwould not have had to use if the Windows Sound System card had a SCSIinterface.


Windows Sound System supports MIDI out, but not MIDI in. For example,Windows Sound System can play MIDI files, but cannot record them from akeyboard input source. To record MIDI in, you must have a separate MIDIcard installed, and you must use it in conjunction with other MIDIsoftware. The Windows Sound System card was designed for business users,who are more likely to need to play MIDI files than to create them.


A joystick port is not built into Windows Sound System because Microsoftbelieves that the typical user uses a mouse to play games. For thisfunctionality, you can install a separate card.
