It's on the free Well Tempered app. along with 7 variations, in case you can't get the RCT file and are in a bind.
This is a great question Dave. I've been using Cyber more & more these past couple of years-however, I've never used it for harpsichords. I always used the Accu 3 (with no stretch..just turn it on & go) or Tune Lab. Tune Lab is FABULOUS for harpsichords while we are on the topic! Lots of non-equal temps already in it…right at your fingertips. For equal temperament and no stretch on Tune Lab you just use it with out taking any readings…it's just a flat line accross when you look at the "tuning curve".
If you do not have either of these machines, and unless someone chimes in that Cyber has all this too…I highly recommend getting Tune Lab. The University will PROBABLY pay for it in your situation. Keep us posted my friend!!
