Roland MC-303 was released in 1996, and is the first groovebox in the series. It embraces a combination of synth timbres, drum machine samples and a built-in sequencer. Its synth part is represented with a rompler which stores a wide range of sounds including classic synthesizers and drum machines by Roland (35 leads and pads from the Juno series, 40 acid basses from TB-303, as well as drums from the legendary TR-808 and TR -909).

The upper part of the device includes effects: arpeggiator with tempo control, quantization with choice of groove, shuffle, delay/reverb for surround sound, flanger/chorus, LFO, low-pass filter with cut and resonance knobs, as well as attack, decay and release adjustment.

In the central section there is a display with a global scroll plate and buttons for kick, snare, hi-hat, clap, cymbals, tom/percussion, and crash. And at the bottom there’s a 16-step sequencer. Groovebox MC-303 is ideal for such genres as techno, jungle, hip-hop and acid.
