How to use the MIDI drums in Guitar Hero World Tour for PC

I'm sorry, there is no definitive answer for the general case of USB mics.

Here an echantillon of my search:

Since you're on Wii, not too many mics have been made for it (at least here in the u.s.) MOST usb mics will work. I own a GH and a RB mic along with a Disney Logitech mic and they all work with RB and GH.

So it's a case of Trial and error...

For the particular case of the PS2 Sing Star microphone, I would said I'm not certain, but likely not.

I actually bought the wired Singstar mic yesterday and tried on GH5 on Wii and it doesn't work. :(

I have bought a set of the Ion Drums (http://www.drumrocker.com/products/index.php) and I have been very happy with them. I typically play expert and the drums are far more responsive than the Rock Band and/or Guitar Hero drums (I've been through two of the RB ones, and one of the GH drumsets). The pads actually have some rebound in them and are much quieter. The drum pedal is okay (and so far it hasn't broken like the GH/RB ones also eventually did), but noisier in comparison.

Be aware that in Guitar Hero you will be presented with the "compressed" view of the drums (ie: four instead of five lanes), the same as if you were using a Rock Band drum in Guitar Hero.
