Currently loading the tool iterates the pattern row and adds the correct states to the checkboxes.
What I want to do is be able to click a checkbox then have the tool re-apply the states of the all the checkboxes ( via an iteration again) i.e. get feedback to the piano interface while the GUI is open.
Also probably more importantly making changes to notes in the pattern editor to notify the same (setting to correct checkbox states while the window is open)
I may be missing something obvious here with notifiers but can not see what yet?
