Bill B. has described the importance of tuning octaves a certain way to get the proper effect for the EBVT (you can't do a proper EBVT on an ETD!). Have you delved into programming octave relationships on the Verituner that might give the desired octave relationships so that the Verituner calculates a proper Bill B. EBVT? </BLOCKQUOTE> Yes, you can use the SAT to tune the octaves the way I do (I don't know about RCT or Tunelab), I use it every day.  It can find the right pitch for each note with the same accuracy as can be done aurally and can be put in a program.  You can also use the FAC program and refine it by using the same technique I do but the right correction figures for the temperament octave have to be determined first.  When I finally am satisfied that I have them, I'll explain how to use them with the FAC program. Anyone out there who thinks they have a set of figures, post them and I will try them and let you know if they are working consistently from piano to piano or not. The difficulty of determining a simple temperament octave like this is what makes me not trust this approach to tuning HT's.  There is too much possibility for error.  If you, as the tuner, don't really understand the temperament aurally, how would you know one way or the other if it what is intended?
