Is there an actual instruction manual for Music Maker 16, like a pdf file or something that I can access? The video tutorials are just not very practical when looking for one particular function, and I haven't found a manual in my disc files.

You need the Plus or Premium version for the Pitch/time stretch and many other effects which you may be missing - assuming you are using the free version. If not please create a new topic giving more information as detailed in this topic.
