im not sure of a rock band style frets on fire but i do know that there is a way to have your drums plug into your computer and use them as a synth. I’m sure within a matter of time someone will develop a program like FoF for drums.
try http://www.unsigned-game.com. compatible with rockband guitar, microphone, and drumset (xbox 360 version only). use Windows XP because they’re still working on a patch for Windows Vista.
1.validate then download
2. install the .exe file
3. it will say that it failed the install but ignore this and plug in your guitar
4. copy your songs folder from original frets on fire install and put in data folder in new frets on fire that u just downloaded
5.go to new FOF folder that u just downloaded then click on fretsonfire.exe then go options and set up your controller configuration
6. rock on to ur songs in style
