[OddsAre]

I ALWAYS record a physical click track as the first thing I do in a session. Pick the tempo, create a click track aux, place the click on the aux, bus to a mono audio track and record about 16 measures of click. Trim it perfect and copy and paste as many as you need. Once it is recorded in as audio it will NEVER fluctuate. Don't rely on the DAW and assume it will keep the click perfect. You have many things that need to access system resources and any number of them can make your click track stutter unless it is recorded in as audio.
