"The Drumulator is a sample based drum machine from circa 1983. The original Drumulator stock sound set was gritty, lo-fi, 12-bit samples of basic drum sounds, which become a classic in many songs of the 80s. The company now known as Digidesign, or Avid (Pro Tools), created sound sets for the E-Mu Drumulator and other sample-based drum machines, called Digidrums Sound Chips. This auction includes 9 Digidrums Drumulator EPROM kits (5 EPROMs in each kit) in addition to the Drumulator stock drum kit, and a custom 808 sound kit from drummob.

The EPROM sockets inside the Drumulator have been outfitted with 5 removable high-quality EPROM ZIFs that allow for easily removing and installing of drum kits.
Note: That the DigiDrums EPROM kits included in this auction are not the originals, but replacements made from the original Digidrums chips (see link below to hear the kits).
