Yup.... kallan kinda hit a interesting note there.
The only reason I started playing drums....is Rock Band. The oem game kit is kinda lame, but it works. The diferent lanes in the game are easy to follow if you know music (i've been playing instruments since I was 7)
Made my move up to a drum rocker by ION (essentially the DM5 non-pro) with a proprietary module. All the same Mideli parts you find on most kits out there. I've expanded significantly and have been wtching ALOT of YouTube vids and have a local drumming bud teaching me some stuff.
Rock Band has a wide variety of bands and styles, with difficulty levels teaching you basics and difficult licks. I know it sounds silly, but if you have a console, pick the game up. When a new song is realsed, i typically "sight read" it on Expert, especially if I know the song. You get a feel for the music and know how it should play. you can then take that principle and apply it right to your kit.
Also, If you have the DM5 already, you can get a GHWT midi adapter and use your kit with rhythm games, or pickup a standalone ION Drum module and just unplug your kit from the DM5 module.
