Version Comparison SE vs Version 7
Some webcasters choose to upgrade to our top of line commercial broadcast software, Version 7.  SE and 7 have much the same look and feel as are  they built on the same source code.  This document lists the advanced functions that are in Version 6 but not SE

Music 1 for Live365
Both Version 7/Professional and SE have a built-in interface for Live365.com webcasters that works hand-in-glove with the Live365 "locker" system.  The setup instructions for importing data from a Live365.com "locker" and then uploading finished playlists to the server are the same for both versions. So get the Quickstart booklet for the version you need to learn how to use M1 itself. But also download this document. It has instructions about linking to the locker.

Traffic & Billing
Version 7/Professional Edition has an optional, built-in commercial scheduling and advertiser billing system. Documentation for the T & B system is included in the full Version 7 User Manual. And you can download a much smaller pdf file containing only the T&B information.
