Groovebox
The term originally presented by Roland corporation on their MC-303[?] now more generically refers to a standalone instrument that includes a combination of any of a drum machine, a synthesizer or a sampler along with a music sequencer and a combination of knobs (potentiometer or rotary encoder[?]), sliders and buttons that allow a musician to control and construct a pattern-based sequence or a song consisting of the more than one such sequence chained together in a live or immediate way.
A groovebox is similar to a Music Workstation[?] except that it doesn't have a keyboard and generally includes more user controls.
