Read your first post from last week (
LINK) and saw that you did not receive an answer. Why did you buy the device if no one ever answered and confirmed that it will work? You name the music store staff "morons" which - to me - means that you have lost any base for a proper argumentation.
Contact
support@mixvibes.com and see if they can help. Unless someone on here uses it for Android I cannot see a solution.
But, on a completely other topic: although mixvibes offers a software for Android that allows you to mix, don't you think if you can buy expensive Pioneer kit a laptop should do it? Just my two pennies
