O que faz a função groove.left.get(i)*50?

Posso usá-la fora do draw()?

  for(int i = 0; i < groove.bufferSize() - 1; i++)
  {     
          groove.play();
          line(i, 50  + groove.left.get(i)*50,  i+1, 50  + groove.left.get(i+1)*50);
          line(i,150 + groove.right.get(i)*50, i+1,150 + groove.right.get(i+1)*50);
  }

We dunno! You should check that out at Minim's documentation pages:

As I've already explained to you in your other forum thread, line() and other canvas-related API shouldn't be called outside draw().

Use PGraphics instead. Then "stamp" those inside draw() via image(), set() or background().
