Tour musicification

Changes made:

• Re-implemented all sounds in Wwise
• Replaced music with basic synth track
  • Track adds note to harmony with each site found
  • Track fades between low- and high- granular synthesis versions based on proximity to activated site
• Replaced train sound with arp synth running parallel to music track (follows harmony)
• Now modulating pitch of tree/site/friend/station activation sounds to follow changing harmony of music
• Each tree has an associated shaker loop, which randomly selects between 24 audio files (4 different shakers/6 rhythmic patterns each) and loops in sync with music and train arp, only audible after activation

Mix is... pretty rough.
