Audiobus is a handy app for iPhone and iPad which connects audio apps after one another. For example you can directly record the synthesizer Sunrizer into Loopy HD for a nice jam. Currently, Audiobus supports a limited number of apps, but the creators of Audiobus promise that more apps will follow soon. It looks at least like a must have if you often make music on the iPhone or iPad.
Audiobus is available now in the App Store and costs 8,99 euro (9,99 dollar). In the following videos you can learn more about the possibilities of this app.
