The Roland MC-50 Micro Composer is a hardware MIDI sequencer released in 1990.

 It lets musicians record, edit, and play back digital MIDI data across 16 channels without generating audio itself.

 It acts as the brain for external synthesizers, drum machines, and sound modules.

working fine. Seems totally unused condition.

power adaptor is 100V though.
