After you've found out the melody (or melodies) you should playing around with some effects and automate them. I often use automation clips for a Filter, Delay or Reverb and especially to regulate the Volume of a channel/instrument. I also use from time to time a gross beat plugin to automate the rhythm of a song. In most cases I record the automations live and polish it after that with some fine-tuned Draws. But keep in mind not to overstate. The Events should fit into your Vision that you had at the beginning of your idea/producing. That's really important.
