Point taken. The fact is, you could still use running intervals in the octave above the temperament section (call it the "5th octave") while you're tuning it. Then when you complete that octave, you might have discontinuity at the beginning of the 6th octave, which was already tuned. But if your octaves were good enough, maybe all you'd need to do is touch up the notes, using running intervals as tests. Of course, this would require more work. So there's not really any reason to do it this way, other than to think about whether it could be done. I just had so much fun doing it with my ETD, so I'm still wired from it. Charles
