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.
Permafrost - (and further thoughts about Nanostudio 2)
Now that I'm getting to know NS2 a little better (not that it takes that long to get to grips with it) I'm really enjoying working with it. It gets out of your way and really lets you just have fun and be creative.
It has the immediacy of working in Gadget, but with a much better timeline (with Gadget you are forced to work in loops/scenes, whereas in NS2 you can work in loops when you want, and more linearly when it's more suitable). The synth in NS2 is just about versatile enough to replace a lot of the synths and romplers in Gadget but it also has AU so the potential palette of sounds is really wide. Obsidian can provide quite a lot of sounds by itself.
Then there is the sampler (and sample synthesis), I'm just scratching the surface but it's really quite good. The only glaring omission is the lack of timestretching - I would really like to see that added just to expand the options of what's possible. But otherwise with the spectral sampling and the modulation options this things is going to be able to produce some really out-there sounds IMO.
