@amchaney a small update to removeOverlaps() seems to fix this for me.

def removeOverlaps ( self ) :

        trackName = 'melody'
        trackName = 'other'
        lastItem = len(self.Tracks[trackName][1].keys())

        for item in range(len(self.Tracks[trackName][1].keys())):
            if item in self.Tracks[trackName][1] :

                s1 = self.Tracks[trackName][1][item]['Clk'][0]
                e1 = self.Tracks[trackName][1][item]['Clk'][1]

                for nextItem in range ( item+1, lastItem, 1 ) :

                    if nextItem in self.Tracks[trackName][1] :

                        s2 = self.Tracks[trackName][1][nextItem]['Clk'][0]
                        e2 = self.Tracks[trackName][1][nextItem]['Clk'][1]

                        if ( s1 < e2 and ( (e1-s2) > 100 ) )  :
                             print ( "Overlap found between: " ,item, nextItem, self.Tracks[trackName][1][item] , self.Tracks[trackName][1][nextItem] )
                             print()
                             del self.Tracks[trackName][1][nextItem]

The loop was putting a list's final item into the range function instead of the length of the list. I'll make a PR now.

There are some other issues in the same file though, which keep it from running correctly

Hello I am still experiencing this issue (attached)

When will this PR get merged?

When I apply this change to BOTH files I receive a new error:

• src/Skeleton/ExtractMidiTrainingData.py (removeOverlaps)
• src/DevServer/ExtractMidiTrainingData.py (removeOverlaps)

Here is my current error:

My goal is simply to use a MIDI file outside of the given examples. It's proving way more difficult than expected with these errors.

Can anyone help me?
