The main item of interest with the LE version is being able to use the Manager module to copy/merge Elements (Banks, Patterns, Tracks, Parts, Scenes, Recorders) and Samples between Octatrack Sets and Projects.
Take elements from any Set/Project, and copy/merge them into any other Set/Project, including all relevant samples, with the ability to remap the sample slots on the fly.
The Chainer is for creating sample chains for use with the Octatrack, and has a bunch of functionality: add / move / clone / delete / random etc; backup to archive, restore from archive. In the full version you can also import straight to the Project.
The Analytics is a multi purpose reporting module that is used by the other modules.
For example, with the Manager, you can click on a Sample Slot, and it will report where that sample has been used in the entire project, which slots, which sample lock trigs etc.
The Options module is for, um, options obviously and end user customisation and preferences. Relevant functions not applicable to the LE version are disabled.
The Support module is for, well, support and logging information, which can also be accessed and viewed.
Hope that helps? Let me know if you need/want any more info or clarification.
