I bought mine at Nadine's in West Hollywood in 1989.
Writing mostly film scores, I must admit I don't use it anymore. Because of its superb dynamics and 16 audio Outs, it is better suited for Hip Hop, Rn'B & pop productions.
Non smoking home studio use only.
It comes with 2 Reference and Turorial manuals.
Needs a CD ROM player and/or SCSI HD to load external sound banks.
Very good working condition, in maintenance at the moment."
