The App Store is home to many fantastic creativity apps, and one of the best of 2011 was Animoog, from the famous maker of synths Moog. It's a full software synthesiser, and one that's been designed from the ground up for iOS devices, while capturing the sound quality that made Moog such a heavyweight name.
Those not familiar with fiddling with waveforms and filters may find it a little intimidating at first, but the great interface makes Animoog just as viable as a fun sonic toy as a compositional tool. It comes with bundles of preset sounds, to let you simply plonk away on the virtual keyboard, or gives you the scope to create your own, starting with a simple waveform.
The controls are so responsive that changing settings on-the-fly is a doddle, boosting Animoog's potential as a virtual instrument massively. It's also a polyphonic synth, letting you play chords rather than just single notes.
There's a recording function too, but it's a tad basic at the moment. It records up to a short 20-odd second sample, before looping it and letting you overdub a new layer. You can carry on adding layer after layer, though, to produce a truly gigantic soundscape. To use as a serious recording tool you'll need to use it as a part of a larger setup, but its great sound quality merits doing so.
Great sound quality and a superb interface make Animoog a must for any mobile music-makers.
