Music people, I need your help - URGENT

[farlaff]

Hi all. I recently purchased a Humble Software Bundle for music making:

I have not even opened it yet, but I've just had to take a very fast trip to the US that ends Friday and I could REALLY use your help. In my country, midi controllers are really expensive and if you could point me in the direction of nice hardware to buy and make the most of the software in the bundle it would be much appreciated. 

Here is an example of things that caught my attention:

Bear in mind that I have no experience with this kind of hardware OR software, so if I sound as someone who doesn't know what he's saying, it's because that is true. :)

Cheers and many thanks.
