Just made my first track with Captain Melody for Windows. Did have some functionality issues with not being able to choose Rhythm when double clicking inside Captain Chord and trying to select, but could change Chord rhythm with arrow, and at the very end it did crash when trying to access that area again. However I was able to get this track out working with the melody functionality) : https://app.box.com/s/bqvppiu2wknev9je6e0h76lmdk7gl5oi
