Roland D2
The Roland D2 Groovebox is a performance-oriented Groovebox. It has Roland's D-Field Controller technology. It has all of the Roland MC-505 sounds and a similar sequencer. All of the MFX effects have sub-menus. The D2 has 100+ sub-menus to sub-sub-sub-menus, and this is why it has fewer buttons than other Grooveboxes.
It is a compact, performance-oriented Groovebox --sort of a smaller MC-505—designed entirely around Roland's D-Field Controller technology. It has realtime and step record modes. It has the megamix option, which is a complicated but nice feature.
This Groovebox was designed entirely around Roland's D-Field Controller technology. The touch-sensitive pad in the center allows the user to program and modify patterns, sounds and effects. The D-Field controller offers 3 modes – Sounds, XY and Spin, which makes it an interesting device for real-time based performance. It takes its 600 preset patches and 30 preset drum kits from the MC-505 and also features a similar sequencer with 150 new preset patterns.
