Houses...
 

Can you put midi files in submitted houses?

no!

I wish.......

You can, but you'll only hear them locally.

Actually, they route now. Trouble is that if the midi's copyrighted, your house is instantly rejected and you can be blocked from submitting for a while....

so i cant use theme song from movies/animes?

Copywrite

DAMMIT

I think that the only way you could do that is if you got written consent by the owner of the midi to use it in your house on graal.
