The Autopan Modulator is an effects processor designed to work around the stereo field of any given audio source. It can be programmed to make your tracks bounce from side to side of the audio field with several modulation options at your choice. If anyway you want to keep it simple, it will allow you to do so manually.
The Autopan Modulator is fully automatable and has the ability to store 32 presets. It ships with a few already pre programmed ones that will show what its all about and may be the starting point to your individual creations.
Installation procedure: Unzip the file, then copy the DLLs into your VstPlugins folder.
