@Richard > As @Erik notes below, the EXPORT mode is free forever - that allows you to manage and export your music for use with CDJs. You get a free 30 day trial of the PERFORMANCE side of the software, and if your trial expires before the DDJ-1000 arrives, you would simply be left with the EXPORT mode. Nothing is lost, and the library and all the cues / playlists / etc. would be there waiting for you when you activate the license included with your DDJ.
