ExperimentalScene updates DarkWave Studio to v4.1.3

ExperimentalScene has updated DarkWave Studio to version 4.1.3.

This release fixes a bug in the drop menu controls introduced in v4.1.2 which caused the drop down menus to display an incorrect list of items to select from. Also some drop menu controls (in particular in the ES MIDI Input and ES MIDI Output) were not drawing correctly when first made visible, there was just a black space where the control should have drawn.
