As shown in the video below routing is not honoured on my system

You are right. I think I misspoke on that aspect of mix-recall.
As designed today Mix recall doesn't actually change the routing aspect of your mix. IOW it will not touch the current routing or add or remove sends to tracks or buses. This can get pretty complex easily because you might be restoring a mix scene where the routing is completely different on top of the current project.
Swapping in the entire routing from a scene to the project might be possible but it would mean potentially creating new buses and deleting unused sends and buses etc. Otherwise you would quickly end up with a mess of merged stuff from the incoming scenes.
 
What we do today is restore the states for the routing. i.e if you have sends it will respect the send enables etc in the mix scene. If a send is not used in the incoming scene the destination send will be disabled but won't be deleted.
 
It might be possible to just handle restoring outputs as you show in your example however, since that is not a destructive operation. Let me think about it some more and talk to some folks here...

Great thanks very much for your input Noel.
 
If there is a way you could add that functionality it would make an already great feature into an absolutely killer one! It would mean you could just set up tons of buses in the master template and then have absolute control over your compression and gain staging during the mix.
 
Maybe a way round it would be to have a fixed amount of buses? I can't see anyone ever needing more than say 20 buses and that way the ones you don't use could just sit dormant as it were
 
The fact you guys pay attention and listen to your customers is what makes the Cakewalk experience a fantastic user experience and is truly appreciated

Just had a major crash by trying to chnge mix recalls during playback and it has totally corrupted the session so it won't load anymore. 
 
I have a previous version pf the session that has the same bus structure. Is there a way I can load my mix scenes I saved in the original session ito the older (now current) session?  I can see the mix recalls in the mix scenes folder in explorer (although they are no longer named what I called them in the orignal session but I can see from the time created they are correct).
 
There is no "file open" type functionality I can see in the mix recall module therefore I cant see a way of trying to open the mix scenes into the new session.
 
Any ideas? otherwise I have just lost a days work

Based in this piece of info http://forum.cakewalk.com/FindPost/3145961
 
Open the browser to the mix scenes folder and drag the scene(s) into the project one at a time and save them again under a new name.
 
To save clutter if the none scenes are used by any other project file in the folder, move the screens out of the mix scenes folder first to another location then drop them into the project and save them again.

Thanks for your clarification Noel. 
I'll look forward to giving it  a spin. 
Most of the songs are all the same and track templates are what makes the job easier. 
There might be overdubs and retakes, but one could make sure they are put in the correct place when done.
