Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
DAW/Sequencer Apps with Tempo/BPM Automation?
I tried using Google to search not only here but also abroad, and yet I'm having a hard time finding the answer. Besides MTS Studio and Auria, are there other DAW and Sequencer apps with Tempo Automation? I normally stick to sequencing in Gadget itself, but Gadget doesn't have tempo automation as far as I know, only time signature changes between scenes, and so I'd like to find something less clunky than MTS Studio/Auria to send MIDI to Gadget with, lol.
