My previous statement explains how I have used Garage Band so far. Now, what I don’t understand, is how to “”Place it on a track” . . I tried to drag Octavox from my finder, )where it was listed below my Mac), to a track in a Garage Band song, that didn’t work, and it disappeared from my finder. As I have stated, I can find nothing in Garage Band related to Octavox plugin. I also have Logic Pro X, same problems as with Garage Band. This Octavox would be so neat if you had designed it as a application working on its own time. I have reviewed Octavox on YouTube, and am very anxious to try it out; I am very much interested in the vocal harmony portion. But I’m about ready to give up on ever getting the hamg of it.
