Most of the Tracks in my main Template are configured to use Direct Routing which is setup as a matrix of possible destinations. This makes it real easy to not only change the routing but also easier to see the routing. However doing this is basically incompatible with Track Presets.
In the pic below there are two Channels on the right named “BkVoc” The one that is selected (Track 17) is what’s in my Template. I saved that as a Track Preset and used that Preset to create Track 18 on the far right which has lost all the Direct Routing settings and is routed to Stereo Out.
An alternative that preserves Direct Routing settings is to use Import From Project instead of Track Presets. Basically create a Project where every Track in it is in effect a ‘Preset’
