Developer Carmine Emanuele Cella (Cryptosound) has introduced Nebula (App Store link) – a real-time granular synth for the iPad.

Here’s the full description:

Nebula brings real-time granular synthesis to the iPad, including glissons and grainlets.
Granulation can be performed on several prototypal waveforms (sines, triangles,
squares, noise) and morphing can be applied between them.

It is possible to store presets and interpolate among them using a single finger through
the gesture mode (activable by the provided button or simply by going to landscape
mode). You can also save and load banks of presets and share them to your friends
through iTunes, using the App page.

In the motion mode, it is possible to control some parameter of the synthesis in a
physical manner by simply moving the iPad in your hands. Finally, all the produced
sounds can be recorded and exported to your favourite platform: the recorded sounds
will be found in iTunes under the App page.

Nebula is $4.99 in the App Store. If you’ve used Nebula, let us know what you think of it!
