This is the Roland TR-77 - a drum machine - Roland's first ever product! This was originally meant to accompany an organ player and sit on top of the organ. Please subscribe and like and get notified about upcoming videos on my channel.

In an upcoming video I will look into adding a MIDI input to this beautiful machine from 1972.
