The EPS (Ensoniq Performance Sampler) was one of the first few affordable samplers on the market. It was manufactured from 1988 to 1991 by Ensoniq in Malvern, Pennsylvania, USA. The EPS was a 13 bit sampler. The EPS used double-sided double-density 3.5" disks, formatted to 800k with ten 512-byte sectors per track. It could also read (but not write) Ensoniq Mirage sample disks. The EPS uses MIDI and can be used as a controller of other instruments, or linked to a PC or Macintosh. The EPS and EPS 16+ were both succeeded by the Ensoniq ASR-10 which was able to read EPS samples and disks.
