The Roland TD-20X Percussion Sound Module brings together over 900 expressive, dynamic drum and percussion sounds plus 262 backing instruments, all powered by the TD-20X's advanced Variable Drum Modeling sound engine. The TD-20X is essentially identical to Roland's TD-20 with the TDW-20 Expansion Board added. The module has been further bolstered with more ambience settings, expanded V-EDIT capability, and an improved user interface. A broader dynamic interprets the strength of your strokes with more sensitivity than ever, and faithfully reflects such subtle nuances of your performance as stick position and hi-hat control. New V-EDIT features include snare buzz, kit resonances, improved virtual mic positioning, and subtle adjustments to layered sounds.
