one of the most unique sounding synthesizers ever made. this is a revision 4 unit with full midi implementation. this unit is completely functional & sounds great. there were roughly 2000 voyetra-8s built & not many of them are rev 4, even fewer have survived to this day! you’ve heard it on eurythmics’ "sweet dreams", on a lot of new order, & on the catchy & irritating "video killed the radio star". you must change the fuse for 220v. unit comes with manual, cheat-sheet booklet (useful for programming), special midi cables (din/xlr), & system exclusive data! i can send you some patches in sounddiver format. if you have any questions, please contact me.
