A recent pitch raise with my RCT started -150c to -250c, so I selected the >100c option on the PR screen. In the low bass I was having trouble getting it to hear correctly, so I went up to C2, tuned that, then started down. Well, the RCT expects you to go left-to-right, at least with that big a PR. I tuned C2, then started playing B1, but the RCT jumped UP to C#2. It apparently detected the note change and just assumed that C#2 was THAT flat.  I finally figured out that I had to set the RCT down one note before playing it, and then it would act like I wanted it to. On a less-than-60c PR it does not behave this way. BTW, a classmate of mine suggests tuning the A's, A1-A5, prior to "calibrating" the RCT for a PR, then take the measurements, then flatten the A's back to where they were. The RCT uses a moving 5-note average to calculate overpull, so if the A's are still in tune during the PR, that throws the subsequent A#, B, C, C# decreasingly flat. Also, the A's are SIGNIFICANTLY flat during the second pass. <div>On 2/16/07, Farrell <<a href="mailto:mfarrel2@tampabay.rr.com">mfarrel2@tampabay.rr.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> My understanding is that the procedure that will yield the best calculated tuning in one pass is to measure all the A's, measure the two adjacent notes at the tenor/bass break, then start tuning a A3 and go up to the top. Then return to A3 and work your way down. Sometimes what I do is measure the A's and then measure all the notes from A0 to A4. Recalculate tuning and start tuning at the low tenor to C88 and then high bass to A0. Gives you an optimal calculated tuning and only takes about five extra minutes at most.
