Thank you for your feedback! I wanted the user to have the ability to have one global effect whilst having the per tab effect override the global effect. I also thought it would be nice if I could have just a single settings section as you said, it feels redundant, but then the user wouldn't be able to change the global settings without closing the per tab setting. I thought I could add a tab system, but I didn't like the feel of it. The speed control is a great idea, I will most likely add it on the next update.

You are absolutely right. I am sorry, I use it to make vaporwave songs on the spot for myself. I will add that functionality and update the plugin for you.

I just added the function you wanted. Enjoy!
