Encountering this NullPointerException whenever I open and close the right settings pane more than once:

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.toLowerCase()" because "deviceName" is null
	at de.dhbw.music.MidiOutputDevice.setMidiDevice(MidiOutputDevice.java:32)
	at de.dhbw.Main.runController(Main.java:82)
	at de.dhbw.Main.main(Main.java:26)

Working theory is that closing the pane somehow triggers the midi setting's onAction with an empty content. Have to investigate further.

think if shortcuts make sense and if yes to what extend (and implement those)

When stopping playback and then restarting it, it is currently not clear where the playback will start. I think the most intuitive way to do this is to just always start at the beginning.

If we actually implement connection to external midi clocks at some point, they will obviously have to take priority.

On timeSignature branch:
When pressing play with no playfield present I consistently encounter the following exception:

Exception in thread "main" java.lang.NullPointerException: Cannot load from object array because "soundMatrix" is null
	at de.dhbw.music.MidiAdapter.tickMidi(MidiAdapter.java:36)
	at de.dhbw.Main.runController(Main.java:132)
	at de.dhbw.Main.main(Main.java:26)

@Rex2002 any idea how recent changes might have lead to this? I'm not sure when I last tested without a playfield.

The current (barebones) UI is massively overwhelmed when it has to handle 30fps video input. It seems like there should be a way to get smooth video and responsive UI at the same time.

For now, sampling video at 10fps seems a good compromise as it makes the UI respond smoothly again while not seeming too laggy.

test different values for image processing, especially GaussianBlur -> Deviation = 0, optimal cut-off for Black&White as well as performance improvement from tree/list with contour-detection

currently the buttons that open the settings pane are very hard to click.
Probably easily fixable by changing the background of the icons to non-transparent, but I fear my gimp-skills are not powerful enough for this
