What is an SPRG file?
An SPRG file contains a compiled and executable program created by SynclavierX, a digital synthesizer application for Mac. It can be opened in SynclavierX to play a musical composition.
You most likely will only encounter an SPRG file if you use SynclavierX software. However, SynclavierX has been discontinued, making SPRG files uncommon.
NOTE: SynclavierX is a program that emulates the capabilities of a Synclavier digital synthesizer, which was a physical music workstation manufactured from the 1970s to the 1990s.
