I don't have the original post anymore. I thought it was a general question 
as to whether you need a freq counter.

And especially if you are doing runs to characterize temperature drift.

Sure.  When I set up a patch for recording I just zero-beat the VCOs in 
against my xtal-derived A440.  And since I have carefully taken out all the 
drift in my VCOs I never have to touch the tuning again (although I can't 
help checking once in a while, anyway).
