I bought Ayu's ayu-mi-x 7 separately and i bought the Limited box too. So it should be something like this;
House:
0 + 1 = 1
Trance:
0 + 1 = 1
Orchestra:
0 + 1 = 1
Euromix:
0 + 1 = 1
Limited box:
10 + 1 = 11
Is this correct?
EDIT : Oh Yeah! I nearly forgot...all of these 5 versions, I bought them from CDJapan!!
