The Prommer is a rare device made between 1983 and 1985 that burns EPROM sample chips for use in the Oberheim DMX Drum Machines. It also burns chips for use in Linn, Simmons, Sequential drum machines, and others, allowing you use you own samples in these devices .The Prommer is monophonic, 8-bit and has edit-ability and sampling. Editing of samples include simple attack, decay, reverse, ring-mod, stretch/squash and other digital bit manipulation. It can send all samples as a MIDI dump to a software editor, so it is possible to edit and then send the samples back to the prommer to burn your custom EPROMs.
