Dynamic Audio Transition Examples

I made this app shows some dynamic music examples 3 different games I worked or is working on, the tracks transition is of a "vertical" nature, (so the point is to switch between different tracks in the same category, and as you will se, they all share the same timestamp).
For "horizontal" transition example see this example:

All music is composed by me, the code's core is from an Audio toolkit plugin that I modified and build upon.
Modified transition functionality, added managers on a layer on top to make it easier to play, change and stop music tracks and sound effects.
