(Am I making any sense?) You're making sense; it's just that CyberTuner is a good bit more sophisticated in its ability to do pitch raises than you are giving it credit for. For the smallest of pitch corrections I think you would probably be right to just offset the VTD and tune slightly beyond the target pitch. But for bigger pitch corrections... RCT knows and factors in _both_ where the strings were _and_ where the strings have to go. It factors in where an individual string was and also where the several strings below it in the scale were, because it knows that in order to put the strings where they need to go, it does not want to be fooled by one note that is off more than all the others. It factors in the place in the scale of each individual string, because it knows for example that the strings in octave 6 will drop more than those in octave 1, and calculates an appropriate, different overpull for each. It can factor in the overall sturdiness of the piano, allowing for the fact that Mason & Hamlins for example need less overpull than Conover-Cables. And it can pitch correct to any pitch level desired, not just A=440. Automagic noteswitching works just fine for pitch corrections too; even when the pitch correction is so big that you have to pull a string above where the next string is, you can still get RCT to switch to the next note by playing piano notes and without having to touch the computer.
