Set definition from tempo & bounce selection

Hi guys, I search the manual and the posts and I can’t seem to find answer to my questions (all tempo definition related).
I have done some experimenting on Cubase 8.5 and will keep on testing / reporting.
I believe any answer to these questions will help our community.

  • Why a track has to be in linear time base for the “set definition from tempo” to work properly ?
  • Why SDFT isn’t denied when track is in musical time base ?
  • What does SDFT applies to: single track, selected tracks, audio clip, events, or all tracks, events in project ?
  • Does subsequent SDFT elsewhere in the project (different events if applicable) cancel or affect in any way the previous results ?
  • Does “bounce selection” sets / writes, or alters the definition in any ways ?
