One of the more powerful tools in Trapcode Form is the Audio Reactor - the ability to map various paramters of the particle system to an audio track. This allows for the development of complex, organic animation without the need to create keyframes for those parameters. Both the parameters affected- and the frquency that is triggering those parameters - can be defined within the Form interface. A layering of up to 5 Audio Reactors, responding independently to predetermined audio frequency and mapped to individual parameters, can be applied to each Form instance. To explore this we will start out with a simple but effective application of this technique...
