Ensoniq MR/ZR Archive
In December 1997 Emu/Creative acquired Ensoniq Corp., an innovator in the design and development of electronic musical instruments. Ensoniq discontinued manufacturing the MR and ZR series synthesizers, and over the years it has become increasingly difficult to locate information and resources for the hardware.
This Unofficial Ensoniq MR/ZR Archive page is dedicated to preserving information about the Ensoniq MR and ZR series synthesizers:
Ensoniq MR-61 and MR-76 64 voice expandable performance/composition keyboard | ![]() |
Ensoniq MR-Rack 64 voice expandable synthesizer | ![]() |
Ensoniq ZR-76 64 voice expandable stage and studio keyboard | ![]() |
Some of the following items are locally archived on this site. Many of the items are links to external sites. Where the external sites or pages no longer exist, I tried to link to the Internet Archive or wayback machine.
