#Novation Launchpad for Keyboard shortcuts

###4 Score and 7 years ago, we used keyboard shortcuts, or something...

Something I've always struggled with is remembering keyboard shortcuts. I'm not sure why. Software I grew up using, they have become engrained in memory. I'll never forget the Photoshop 6 shortcuts that became etched in my young impressionable mind. I also dislike using the mouse. It feels so inefficient to move from keyboard to mouse, especially being in flow.

##My brain is too small, helppp!

With the bombardment of great new tools, I've been forced to abandon shortcuts in most applications. This was until my brother showed me a peice of hardware he is using to produce music.

#Fundtimentals of programming

###What is programming?

A computer program is a set of instructions.
A sequence of a set of instructions.

The art of programming is to take a larger idea and break it apart into smaller ideas.

Computers will do exactly as you tell them, so you need to make sure your instructions are right.
