Hey Dave,
Avidion Synchronize has all the capabilites that Trapcode soundkeys has but also has the following:
– More accuracy (More frequency bins and also the sound is filtered)
– Fall-off/Fall-on controls
– A built in smoother for the output
– The ability to drive the velocity and use the current keyframe value
– The ability to place layers on the beat
All of this can be seen in the training video at http://www.AvidionMedia.com
If you have additional questions let me know!
