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.

Chord Detector - Tiny Mac Status Bar App
Hi, I'd like to share this little Mac app I made a couple of years ago, for searching the chords of the songs I'm listening on iTunes or Spotify.
So, it basically searches the ultimate-guitar for the songs you are listening on iTunes or Spotify, and returns you to the most starred chord - if any available. Holds up to 20 chords in its history.
Also, it's completely free and open-source!
