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.
Ideas to get Beatmaker 2 and audiobus to work together better
Well I wondering if down the line in a future update, there can be an option that when recording audio into beatmaker 2 or any other app that allows you to do loop recording, that can automatically stop the recording once the set amount of bars pass. This will be a very useful feature because once you record a loop you don't end up stoping the recording too early or too late and thus ending up with a loop that is a little shorter or longer than you intended.
Another feature that I think would be useful is one where once you press the recording button to stop a recording, the play action of the song stops entirely as well and the other app being recorded into is left paused.
Now Im not sure if these features are possible, but I believe they should be able to be turned on and off for people that may not want to use them if they are considered and think they would make recording into BM2 as well as a few other apps a lot more smooth.
