Wow - Fantastic Update
I has used the previous versions faithfully for several years until it stopped working somewhere around iOS 7 or 8. I had reluctantly deleted it since they did seem to come out with any updates. Im glad I checked again and discovered a recent update at the end of 2015. Not only does it work better than before they let you and let you save mixes of custom sounds it added electronic "brainwave" mixins. My only wish is that they would add more more music loops. The 9 they include are great but overused. I would certainly pay a couple dollars for some more. Another feature I would love to see us the ability to import you own sounds to create your own custom loops. How about software developers?
