buttons

when a 'press' or 'release' is fired, the e will look something like this

{
  button: '',
  deltaTime: 1, // seconds since last press or release
  message: []   // raw midi values
}

the button values tell you which button was pressed. i used the labels on the launchpad, so they should be straight forward, but i'll break it down anyway

the round buttons across the top row are as follows

the round buttons down the far right column are as follows

all the other buttons are called 'block's which will also come with x and y values corresponding to the column and row of that block
