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.
Chord apps that could filter *incoming* midi
I’ve just watched the new features on Chord Maps 2 and it reminded me of a question I’ve brought up on other threads without getting any traction: Why, oh why, can’t any of the various chord apps (and I think I have most of them) filter incoming midi notes so that they would conform to a chord or chord progression? Especially apps like Suggester or Navichord or Chordbud, etc., that let you build a sequence of chords. Then you could improvise via midi keyboard and your notes would conform to a chord progression. This seems like a feature that people would like so I have to assume that there’s some problem that prevents this kind of thing. Why can’t it be done?
