Windows/MAC Desktop App Developer

Here is a source code link. [login to view URL] The project is actually confidential and I cannot share the entire solution. So here is what I need from you... In the file [login to view URL], the script is creating the logic for the Drag and Drop functionality based on the JUCE framework. Right now, I have it working on windows but the StringArray files (Line 82) seems not to be updated with a new sequence once the sequence has been changed. The drag and drop function does not work on Mac at all. So I am trying to figure out if I need to store the data in something other than a String Array for it to work on mac. I essentially need your help with the logic in the [login to view URL] file alone. I have narrowed it down but I need help getting the logic right. I need you to look at the code and the logic of the code to see if there is another way to write it so that #1, it works on a mac and #2, it updates the midi sequence. You can send me your suggestions or re-works of the code and I will try them on my end.
