The Roland MC-505 is a groovebox conceived in 1998 as a combination of a MIDI controller, a music sequencer, a drum machine, and a desktop synthesizer with many synthesis features: arpeggiator, oscillators, and voltage-controlled filter, control of attack, decay, sustain and release, different envelopes and 2 Lfo.

It was released as the successor to the Roland MC-303 and is a compact version of the Roland JX-305 Groovesynth without the full set of 61 keys.

The key features of the MC-505 are: In 2000 the Grand Royal record label released a compilation album At Home with the Groovebox, where all the artists contributed a track primarily using the Roland MC-505.

Artists included Beck, Money Mark, Air, Jean-Jacques Perrey and Pavement.

This was considered to be an interesting and well received album.
