The Roland MC-303 Groovebox collates some of the company's most iconic synth sounds and beat machines into one compact, easy to use model. Ranging in genres from jungle to house to acid, the MC-303 brings together 40 synth basses from the TB-303, 12 kit sounds from the 808 and 909, and 35 synth lead sounds for an all-in-one song production center. Able to operate off batteries and made to be on the move, the Groovebox is a fun creative experience with plenty of muscle behind it.
