Doubletime_v2_0
doubletime_v2_0_2.qml There are a lot of forum topics about getting certain plugins ported from MS 1.x to 2.0. I have doubletime.qml working. I hope it helps some of you get going on your other plugins.
Doubletime simply doubles the length of all the notes and rests in your selection and creates a new score with the result, so you can copy/paste back into your score wherever you like.
