n-Track has been updated with a very complete implementation of Audiobus, including actual multi-track recording!
While not as impressive looking as Cubasis, or Auria, it does have nice features like automation and is at a much lower price! This update also adds support for AudioCopy/Paste, making this a well-rounded little DAW for both iPads and iPhones.
What's new in n-Track v2.1:
- Support for Audiobus!
You can now send audio from other apps to n-Track, play your favorite instrument app and record the output inside n-Track alongside the device mic/line input.
- Each Audiobus app can be recorded to a separate track.
- Option to record/process audio when the app is in the background.
- Support for AudioCopy and AudioPaste: transfer audio files between compatible apps
