Roland MC-505

The Roland MC-505 is a groovebox conceived in 1998 as a combination of a MIDI controller, a music sequencer and a drum machine, and also has some of the prime features of synthesizers: arpeggiator, oscillators, voltage-controlled filter, control of attack, decay, sustain and release. 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.
