The simplest way to transfer audio to the plugin is to drag content from the DAW to the Idea view in the plug-in.  Most DAWs that support external drag and drop will allow you to directly drag and drop audio clips to/from the plug-in. Momentum Free, Basic and Pro all support the drag and drop of ideas from the plug-in to your DAW. Drag and drop audio from your DAW into Momentum is supported only in Momentum Pro.
