I have. And I THINK I get the differences.  Which is the best to use for a failsafe? In that, No matter how much I tinker and/or adjust settings in the mixer I can pull it up (workspace, snapshot, etc.) and it'll be good to go. As in, if I pull this up I KNOW for certain I'm going to be able to have audio routed the way I need it to.

Hi Matthias,
has anything changed in the manuals? I was firmly convinced that I once read a chapter that listed what exactly is stored in snapshots and what is stored in workspaces.

But I can no longer find it. Not even in the TotalMix FX online help. In addition to the UFX III manual, I also looked at the UFX manual (my 1st RME recording interface). I searched for the keyword "workspace", found about the same chapters like in the UFX III manual, but no chapter which explains the differences.

Did I overlook something, do I have something wrong in my memory, or did the chapter accidentally get lost during a major revision?

If I may make a suggestion. I think it would be very useful to add a chapter about the differences and short description how to save the whole setup.

What I always use in combination (IMHO, results in the best handling):

1. always make a backup using TM FX: File→Save Workspace As. Whenever something changes in the routing or the window position.

2. use Workspace Quick Select because this way it is easy to restore the last saved workspace.
There are 32 of such Workspace Quick select slots. The first 8 slots can be recovered easily by using the key combinations ALT-1 … ALT-8. This gives the possibility to group and access up to 8×8=64 snapshots rapidly, just in case 8 are not sufficient for all of your use cases.

I loaded a workspace that I saved with the knowlege that EVERYTHING would be 'frozen' as far as settings (including snapshots) but the snapshots were different after loading.

Absolutely.
