This is the JV-1000 catalog published in 1993.
This is one of the representative models of the heyday of workstation synths, beginning with the Korg M1.
Basically, it consists of synths, effects, rhythms, and an MC-50MKII-like sequencer.
This configuration allows you to add expansion boards to expand your tones.
