“funny” side note: using my ancient FaderPort Classic for navigation instead of my Avid S1 is much faster and effective, because Nuendos mixer and project window both follow the nudging and banking commands from the FaderPort.
So I find myself using the FaderPort and the S1 parallel 
FaderPort for navigation and transport, S1 for mixing, pan, EQ, dynamics…
thank god I didn’t throw away this old controller years ago…
