We are well aware that songs can be created on the computer with literally nothing else but a mouse and a keyboard.  Although Ableton gives you the option of using live production techniques inside of their software, it can also be used much like a composer creates a symphony using nothing but manuscript and a pencil.  Both approaches have their benefits, and with Ableton a mix of both is usually the best approach to creating music that is both digital, yet humanistic.  Hardware for this purpose usually consists of some sort of MIDI controller to help aid the producer in inputting information. But that is not the only means of inputting information into your DAW.  In the case of the MIDI controller, your computer itself acts as the hub to which all hardware can be attached – but what if you had another type of hub to handle this task?  A digital audio interface with multitudes of connections is quickly becoming an alternative for those who are looking to beef up their systems.  It has the benefit of not being attached to your computer, and therefore only taking up its own power and system resources.  The benefits here might outweigh the costs.  http://createdigitalmusic.com/2013/04/3-approaches-to-accessorizing-the-studio-spl-softube-ua-at-musikmesse/
