Adding a music scale question fails. Only returns to add question form again

[cstones]

Hello, I've been reviewing the code for inclusion into Moodle 2.7 and Moodle 2.8 and
it seems that after creating a quiz activity and then trying to Add a new question the music scale
question type returns to the same /question/question.php page the "Save Changes" button is on.

In other words, the "Save Changes" button reloads the page and the question does not get added.
This happens in Moodle 2.7 and 2.8 I feel it might be a validation error.

javascript console in Chrome reports:
'Range.detach' is now a no-op, as per DOM (http://dom.spec.whatwg.org/#dom-range-detach).
as well.

If you want to fix this and make a pull request, I am more than happy to update the plugin. But, I no longer work in higher ed and, thus, would love to turn these projects over to someone who could maintain them. Also, you should look at qtype_musictheory which is the combination of the 3 music plugins back to the original author, Dr. Eric Brissom, and 2.7 compliant! https://moodle.org/plugins/view/qtype_musictheory

His new project is the other reason I do not support these plugins anymore. But, I keep them around for people who are using legacy Moodle versions.
