NOISE is great, though it'd be even better if we could more easily integrate it with other apps via Audiobus.
Looking at other comments, it might be that Roli can't expose the Swam instruments to anything outside Noise which means the Audiobus version would need to be different to both the iOS AU and app versions. This is a shame, the Swam instruments were one of the biggest draws for me. I've started working on my ipad a lot, having used Cubase etc on desktop since the early 90's. The capabilities are astonishing, Roli being one of the best examples, so I'm disappointed that business reasons are possibly limiting me, rather than technical or development-creative.
