Just a quick post with the actual app store description:
With Audiobus, the revolutionary new inter-app audio routing system, you can connect your Audiobus-compatible music apps together, just like virtual cables.
With a simple and clean interface, easily connect the output of one Audiobus-compatible app into the input of another. Use Audiobus to play a synthesizer live into a looper or multi-track recorder, or use one app to manipulate the live output of another.
You’ve never before been able to use your apps together like this.
The ever-growing supported apps list includes:
- Rebirth for iPad
- JamUp Pro
- NLog Synth Pro
- NLog MIDI Synth
- Loopy HD
- SoundPrism Pro
- MultiTrack DAW
- sir Sampleton
Note: We recommend using Audiobus with iPad 2, iPhone 4S or newer devices.
Audiobus is priced at $9.99
