The music practice app, Anytune, has been updated today to version 3. It looks like a solid way to run your music on any iOS Device for practicing along to it. The update includes a face-lift and some tweaks to zoom in on waveforms, for selecting loops to practice on. They've also added "LiveMix", a new live input mixing feature. This allows you to run your own instrument in through Apogee JAM, iRig, or a Mic.
Although the app is free (Ad supported), they have a complicated tier structure on features. You can't just In-App Upgrade from the free version either. You need to buy the $10 "Pro" version of the app, which includes "Pro Audio Quality"... implying you get "Shit Audio Quality" in the free version, I guess. Also in Pro is the ability to import music from iTunes, Dropbox, and email. Along with "Groove Skins" and AirPlay support.
To get to the HQ tier is an additional $5, as an In-App Purchase from the "Pro" version or by buying the third app, "Pro HQ". This includes "FineTouch™ EQ", and the LiveMix functionality.
Here is an overview video. I have 3 promo-codes for the "Pro HQ" version to give away. Hit that Facebook Like button at the bottom of this article and I'll select the winners at random tomorrow morning!
