I thought that some of the forum folks took it upon themselves to build some little but powerful utilities, and one of those I think created some sort of an inventory of what was used in a project.
Here is the link to the thread that contains descriptions for all of these user-built utilities and such, as well as the links to allow you to go and download them.
http://forum.cakewalk.com/FindPost/3238243 There is at least one of those that might give you assistance with figuring out old presets or synths and such, to the best of my awareness.
I have always created such lists of what is contained within each project using Notepad/Word/Excel/Screen-shot and placing that information within a sub-folder for each project named Project Notes, and that approach has worked for me for well over 20 years. (I was in technical support for eons, and we such folks try to leave trails of breadcrumbs via notes - albeit sometimes on napkins - to help us keep things running when things aren't running).
I hope one of those utilities helps you - while you are in there, I would encourage you to look at some of the other ones - you may find several powerful and helpful creations there. Those folks certainly have put in some quality time and created quality tools they then freely have chosen to give us - you can't really beat that. Another reason I love these forums and the folk within :)
