Fidelity Media has released MegaSeg 5.5 (http://www.megaseg.com), an update of the Mac-based DJ and radio automation software. According to Fidelity Media Founder Jason Cox, the new version — a free update for registered users of version 5.x — contains over 100 improvements.

For example, it debuts a new Wave Viewer with trackpad beat syncing and scrubbing for visual beat mixing and cueing. The feature is compatible with MacBook trackpads as well as Apple’s new wireless Magic Mouse and Magic Trackpad. In addition, MegaSeg 5.5 integrates album art displays within redesigned decks and track info popups.

The category browser has new audio and video filter options to help find specific media types fast. What’s more, MegaSeg update 5.5 adds 3x gain controls for softer tracks, minimum title and album separation rules, and video icons in list view.

MegaSeg is a self-contained DJ music mixing and radio automation system that enables DJs and radio stations to put their music libraries on their Mac and segue or beat mix between songs or music videos, trigger sound effects via hot keys, note requests via color-coded request lists, cue tracks via a second sound output, create dynamic scheduled playlists, and program timed playlist events. MegaSeg has full integration with the iTunes library and playlists, including compatibly with songs bought from the iTunes Music Store.

MegaSeg 5.5 costs US$249 for new users; users of version 1.x through 4.x can upgrade for $79. It’s a Universal Binary app, so runs natively on both PowerPC and Intel Macs. It requires Mac OS X 10.3 or later. A demo is available for download.
