Thinking about it today (before reading Israel's comment) it occurred to me that the overpull for the large pitch raise function of cybertuner is much smaller than the small or medium modes. Thus, to do a 300 cent pitch raise in just one pass wasn't even leaving the piano at pitch. I would be very nervous doing any overpull on a string that flat. My method even at half a step, is to go through it quickly and bring the string up to pitch, then again with overpull then a fine tuning. The first pitch raise I usually take things rather slowly, so it may take 20 minutes to pull things up to pitch. The second one might take rough ten to fifteen minutes and the final tuning usually around an hour. Gary On 2/4/2011 7:49 AM, Avery Todd wrote: > Thanks, Israel. That hadn't occurred to me.
