I made the pads in a seperate draft and turned them into loops though this still became too large to work with. Can't add anymore. The bass is made up of 1 one-shot sample re-tuned multiple times and ran through a pulv, it took ages to make though resulted in quite a nice tone.
There is no key signature for A# major, which was the question. A# minor's key signature is the same as B Major (A# is the 6th degree of the B major scale). You can also argue that there are no minor key signatures, but only minor keys, since minor keys are the 6th degree of any given major key signature (with some variations). Similarly you would never see a key signature for A diminished. So :P
