David I., In RCT the notes used for sampling are As. If the piano is so flat, that the As don't register, I simply use the A#s which register as As because the piano is so flat. That works well enough to use the calculations for the pitch raise. Then, when that's done, I resample the As which are now registering as As, albeit still flat (just not so flat!). Then I fine tune, probably somewhere around A435-37. Then I come back again, at some point in the near future, and do another pitch raise and a fine tuning aiming for A440. Clair
