MC 303

TheRoland MC-303is the first of a series of musical instruments known as agroovebox. It combines a simple sound module with asequencerto 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 attention it received at its launch, the MC-303 has more in common with other MC prefixed synthesizers (such as theRoland MC-202), which contain built-in sequencers, than it does with the famousRoland TB-303. As the first Groovebox, the MC-303 was the first in a line of inexpensive products specifically targeted towardshouse DJsand amateur home musicians rather than professional producers. It was superseded by theRoland MC-505. It is the predecessor to theRoland JX-305,Roland D2,Roland MC-307, Roland EG-101,Roland MC-09,Roland MC-909,Roland MC-808, and most recently the Roland MC-707 in 2019, along with its more portable sibling, the Roland MC-101.
