Since you are on XP, try the registry method to rename your mic without passing by morphvox, you can also lower the delay from morph vox if you fail to get the registry method to work, but there will still be delays, read all the comments above, they will help.

I hav headset C-media USB audio device

And what about joining irregular headset to windows Vista PC, There rename it and than connect to windows XP PC?

I know the ins and outs of exe modification, you can do whatever as long you do not insert or delete a byte, you can only modify.

Anyway whether or not this is legal is a very long discussion. and this is not the place for it.

what we still need to do is to enable band mode.
you see, the mic automatically reserves the keyboard as the input device, leaving the second player without a controller.

Any USB game controller will enable band mode, but you will not be able to select a side as the game will not recognize any input from it.

what needs to be done is to mask a regular USB controller’s input as a GH guitar input.

another theory is to use another set of input keys on the same keyboard ( or other USB keyboards) as inputs for the second player.

if you feel like it, please move this discussion to the forums at http://forum.angrybyte.com

BTW, I don’t think that this method is any different in legal terms than create any way to fool the game in order to play with a ordinary mic. As long as the game publisher receives money from our hands and we don’t make illegal copies of the game, I think it’s OK. No?
