In effort on bug 253:

Browse Source 
Get rid of Pitch Up/Down radio buttons. 

Change Semitones validator back to allow negative entries. 

Make "From:" and "To:" for Pitch be consistent with formatting for Frequency. 

Make the pitch wxChoice narrower. It's at most only 5 characters. 

Remove empty comments. Cruft.
