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.
Clock control app or plugin?
I need a Link enabled app that specializes in all things tempo. It can record and edit a tempo track in a variety of ways to drive other Link supporting sequencers. Ideally it would be auv3 that could control Audiobus or AUM from inside of it. Maybe even a feature built into AB or AUM?
With this imaginary app you could:
-Tap in tempo to directly control the transport like some Mac software used to do. Thinking of Performer. I.e. sequencer playback stops after you stop tapping and waits for the next tap. Then the app uses its own internal clock to create a tempo track to drive the sequencer.
-Tap in tempo while the transport is running and the app responds afterwards like AUM does now for real time tempo control.
-Record these actions in an editable timeline format
-Tweak tempo change rates between recorded changes.
Use case: let’s say you have a heavily quantized midi track that you want to add expression to by speeding up and slowing down in places. You could play it back and tap the tempo beat by beat and the app will record the taps and interpolate the times between taps as tempo changes.
NS2 has a fantastic Linked tempo track that does this but you have to manually enter tempos. This is tedious for a really rubato piece.
Another use case: you have an audio recording of an expressive performance and you want to add midi tracks to it. Tap along with the performance and create a tempo track to drive a sequencer that syncs with the original audio.
With something like this any existing Link enabled sequencer or DAW would immediately have advanced tempo track abilities.
Is this feasible and would anybody else have use for it?
