The Titan Twins - Dynamic Leitmotiv Sub-Pack 9 holds a total of 45 dynamic video game music loops - 12 starting points, 33 variations - with 1min 4sec each, which amounts to almost 2 hours of interactive music without counting sub-loops.

The pack aims to serve as a primer to dynamic music and lets you explore its capabilities by providing 45 dynamic music loops for your game’s Road-trip, End Credits or Rock needs. It includes variations on Rock music, great for road-trips, ending credits and can also be used in mini games or tutorials. All the loops can be used to transition seamlessly from one to the next, no matter which one you chose. They are kept in the same tempo and key with the same musical material and pretty much escalate in intensity from lowest number to highest number.

This pack is a smaller part of an effort to combine every sort of dynamic music and leitmotivs I could think of to help out especially the indie game dev scene with a musical toolbox that covers a whole range of applications with almost endless variation possibility. In total, the full pack amounts to over 70 hours of music with suggested starting points to get you started and move faster. 
Important note: This pack is a cheaper, sized down version that includes dynamic music tracks for Roadtrips, Credits, Ending Themes and Rock Bands. You can find the full pack under my assets labeled as Titan Twins - Complete Dynamic Leitmotiv Pack at a reduced rate.
