I bought the Modern Pop Acid Loop from Producerplanet to use in Music Maker. It was not available through the IN-APP store. I downloaded and extracted the folder as explained and when I use Add New Soundpools, I browse to the folder and select it. It looks like it will add it, but nothing shows up in my Soundpools list. in looking at the folder, It doesn't have the breakdown of folders like instruments nor the XML file. I'm assuming that Acid Loop packs don't work in Music Maker?
