History

was instrumental in working with Roland Corporation in introducing high-end sound modules and sound cards in the mainstream computer game market in the late 1980s through early 1990s.

Further confusion may have also occurred as Roland's own marketing materials such as magazine ads referred to the card as the Roland LAPC-1.
