otes. In general, the effect of \TransformNotes{input}{output} is that notes commands in the source will expect their arguments to match the input pattern, but the notes will be typeset according to the output pattern. An example is extracting single-instrument parts from a multi-instrument score.
fixmsxpart corrects note spacing in a single-part MusiXTEX source (possibly derived from a multi-instrument score and as a result having irregular note spacing).
msxlint detects incorrectly formatted notes lines in a MusiXTEX source file. This should be used before using \TransformNotes.
