The EPS uses MIDI and can be used as a controller of other instruments, or linked to a PC or Macintosh.
The EPS was eventually superseded by the EPS 16+ which upgraded the sample-size to 16-bits and added a 24-bit effects system. Other improvements included CD-ROM support in the optional SCSI interface and FlashBank storage for the OS and favourite sounds.
The EPS and EPS 16+ were both succeeded by the Ensoniq ASR-10 which was able to read EPS samples and disks.
Ensoniq EPS-16+, released in 1991. The EPS-16+ was very similar to the EPS. Its main addition was integrated DSP effects and stereo audio routing. Due to the upgrade to 16-bit audio, the Output Expander on the 16plus was different, instead providing three pairs of stereo outputs, two from before the new effects chip. |
