The TD-30 is a new V-Drum module that replaces the TD-20 and TD-20X. The main new features are newer better Supernatural sounds, USB and USB/MIDI, more control over ambience, and a new Hi Hat functionality. The new VH-13 hi hat cymbal boast better open and closed control and better playability over previous models. The TD-30 has the most inputs and outputs of any other V-Drum module so this is the one to get if you want to have a large kit or have direct output capabilities. The TD-30 also builds on the previous generations modeling technology to give the most realistic playing experience while also being the most customizable module to date. With several 3rd parties making kits for the Roland modules you should also be able to easily expand on the internal factory kits without much effort unless you want to program your own kits. Even programming your own kits is a ton of fun once you get the hang of it. The TD-30 modules are shipping by themselves in June 2012.
