Just wanted to say that I love the program. That being said, it is not very beginner friendly and has an incredible amount of bugs. Just thought I would note a few down that I have come across.
Sometimes, usually when I am trying to get a song longer than 2 minutes out of it, the render just fails. No error messages, nothing. I suppose technically it succeeds, but there is no file created.
A lot of the time when I extract a song to edit it, I have to save it, close the program, and reopen just to make changes to the song, and have to do the process again when I want to render.
