Interesting subject.
I use my own templates exclusively that I have tweaked over the years-running 14-16 mics in a small room requires that.
With the same mics and d.i.s. in the same room it would seem pointless to set up per project templates as basically only volumes change.
As for presets,everyone wants instant playback,especially recording live and applying VC64 (master mix) or whatever the X3 equivalent is (Prochannel?) to the main bus can instantly transform a mix as playing back a dry take can sound pretty thin without presets.
Pretty sure there have been some pretty flash templates created and discussed in Techniques before?
cheers
