Hi,
if you happen to own a Steinberg VSTi (such as Halion 5 or The Grand 3), the standalone versions of those provide a metronome that itself is implemented as a VST3 plugin. It can usually be found in folder:
C:\Program Files\Steinberg\HALion 5\VST3 (for Halion 5) and is called metronome.vst3. I copied the file into the common VST3 folder: C:\Program Files\Common Files\VST3\Steinberg.
After a restart of Cubase or Nuendo it is available as a Generator plugin, which can be inserted into a new audio track. And there you have your dedicated click track. The metronome is not configurable, but for getting a simple dedicated click track it works.
Cheers,
Mike
