The Roland MC-303 is the first of a series of musical instruments known as a Groovebox. It combines a simple sound module with a sequencer to record and store notation, along with controls aimed at encouraging the musician to improvise the music while it is playing. Despite the number in its name and the hype it received at its launch, the MC-303 has more in common with other MC prefixed synthesizers, which contain built-in sequencers, than it does with the famous Roland TB-303. As the first Groovebox, the MC-303 was the first in a line of inexpensive products specifically targeted towards house DJs and amateur home musicians rather than professional producers.
