I made a small correction in the script, which presented error in long notes.
I also moved the download to GitHub for easy versioning.

Wow, this will be very useful!!

Nice, thanks for the update!

Thanks!

Thinking back, I thought there was a button for this. But, it turns out that the Trim Durations button just 'visually' shortens the notes so they don't overlap. Helps clean up notation, but the notes still play as recorded or entered.
Thanks!

Many, many thanks, this is going to be extremely useful to me!
 
Will it find and correct instances where a note exactly overlaps another? I sometimes get exact duplicates in a section, possibly because I've been copying and pasting MIDI clips.  I then have to spend ages testing deleting suspect notes.

In this case, you can use UNDUPE 2.CAL (my corrected version of UNDUPE.CAL).
 

This script becomes deprecated from the improved "CleanTrack.cal" script developed by sping.
