Good news! As regards the Supperware Head Tracker, Bridgehead 1.11 (released today) has a HeadPose profile that works with Nuendo.
To use the new profile, you’ll have to go to the Bridge Panel in Bridgehead, ‘Show file’, delete Profiles.txt, and click ‘Refresh’. Assuming you never created any custom profiles that you want to copy over. Otherwise, the profile that works looks like this:
Nuendo (HeadPose, 25Hz)
/head_pose
0,0,0,0,-pitch,-yaw,-roll
local 7000
Note that you’ll still need to upgrade Bridgehead, as those padding values aren’t recognised by earlier versions.
I had no help from Steinberg with this but I have poked around gently inside the .dll and it looks like it is supposed to support a number of formats (HeadPose, hedrot, OpenTrack …) and to customise the format and port via a configuration file somewhere. But I suspect that Steinberg isn’t supporting this properly because it doesn’t yet work properly. So far, HeadPose on port 7000 is the only profile I could get to work.
You’ll have to turn the tracking rate down to 25Hz in the Bridge panel, and occasionally disconnect and reconnect so that Nuendo can catch up with output data if it starts to get laggy …
Feel free to request such stuff directly via the Supperware support email address in future! (PS Thanks to Subin, who brought this issue to my attention that way.)
