I downloaded the content packs I wanted, but when I install it, the soundpools still do not appear - so my question is: What is the install path after it extracts itself into the temp folder?
When you download content packs and install them as per instructions, they are automatically installed to where they belong. You won't find any folder called content pack. What you do find though, is more keyboards, or guitars etc, when you check out the soundpool. Sometimes hard to spot 'cos none of us spend our lives memorising soundpools before downloading more, so the difference is not instantly noticeable.
