Once you have scaled the algorithm output values and received derived pitch values, you can perform modification in order to adjust specific pitch values. This is not necessary, but you might find the option useful in certain instances. To do this, enter a value r to be replaced and a value s to substitute in its place in the text boxes of "Convert each __ to a __." Both values must lie in the range of 0 to 88. Then click the Convert values button. All instances of r in the list of derived pitch values will be replaced by the value s. You can apply modification multiple times if you desire. You can also click the Start over button and rescale the output values if make a mistake or are not satisfied with the modified values.
