Hello, when my pr will be merged?

Hi, I won't have time to test it before 10 days unfortunately.
Multiple points:

• Are you the creator of the music? If yes, do you confirm the license is GPLv3+?
• If not, where did you find it and did you check the license is coherent with ours?
• Would it make sense to have an option in the menu to choose between the old and new audio? This way the users can choose which one they prefer.

Yes, I'm author, if you want I'm can send on email source LMMS file project
