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.

Who said it's gone and can't be like it used to be? (iOS album teaser)
Teaser for new album from Neuhold Mauseth and Powell - featuring a variety of international artists! 
Martin Neuhold (Germany), Guy Beeri Mauseth (Norway) and Colin Powell (UK - me!)
This should be available soon and (apart from some of the additional artist vocals/guitar) was recorded on iOS devices. It was also a great exercise in international collaboration of musicians.
It was designed to hark back to the days of vinyl LPs when you would put an album on the record player, make yourself comfortable and settle down reading the sleeve notes as each track played. You will be able to download a booklet which will include the sleeve notes as seen in the video
In most cases the singers wrote their own lyrics to our music.
