A demo entitled "More Guitar" written by Pelle Piano on the Ensoniq ZR-76 released in 1998. This is an amazing workstation and synthesizer built upon the MR series keyboards previously released in 1996. The ZR series keyboards rock the EXP 4 Perfect Piano Expanison Card by William Coakley and still today, produce a rich, unique warm sound one could expect from Ensoniq. This demo was written entirely on the ZR-76 using only stock sounds.
