What is an LS3 file?
Musical style file used by Band-in-a-Box (BiaB), a program used for creating musical accompaniments; saved in a plain text format and contains a musical style generated by the user or by a third-party seller; used for creating music for a certain genre, such as Rock, Country, Jazz, or Hip-Hop.
BiaB styles also use the .STY file extension, but this style format is used for the styles installed with the BiaB software or those purchased from the PG Music BiaB online store.
