New Name, Same Great EffectPhysion (formerly known as Fission) is the first plug-in to use our ground-breaking Structural Effects technology - A new method for processing audio. It allows you to split a sound into its transient and tonal parts, independently manipulate them using Eventide's world-class effects and then fuse them back together. With the ability to add effects and dynamic controls to the transient and tonal sections, you can produce a wide range of effects, from the subtle to the extreme.For more information on the Fission/Physion name change, click hereLearn more about Structural Effects Features Split audio into ‰ÛÏTransient‰Û and ‰ÛÏTonal‰Û componentsRadically re-shape a sound by soloing the Tonal and Transient channels.
