The SW1000XG is a top-of-the-line XG-enabled PCI soundcard released in 1998. In addition to its on-board XG synthesizer, it can also be expanded with a PLG100-series plugin board.
The latest Windows operating system that this card works in is Windows XP. While the audio portion of the card will work under Windows Vista and 7, the MIDI system does not. However, it may be possible to get the MIDI system to work on 32-bit versions of Windows 7.
