Developer Wooji Juice has released an update to Grain Science, its hybrid granular synthesizer for iOS.

Grain Science 1.3 offers four main improvements:

• The first and biggest news is that Grain Science is now a Universal app. This means that it runs on both iPhone and iPod touch, as well as iPad. If you’ve already purchased Grain Science for iPad, and you have an iPhone/iPod touch, you can just install the updated version on your pocket device and start making music — and if you don’t have an iPad and have been missing out, welcome aboard!
• Arpeggiator 2.0 – The Chord mode is a little cleaner and tidier, but the major upgrade is to the Step mode. The sequencer now supports 32 steps, a much wider range of notes, and allows you to sequence more options.
• Ribbons and Velocity –  In the Settings, you can now switch the keyboard for a “ribbon controller”. This replaces the traditional piano keys with metal strips; the position of your finger along each strip controls the velocity for that note. It’s directly tied to the MIDI velocity, so if you have the ribbon controller enabled and happen to be using a MIDI device, you’ll see the ribbons reflecting the force with which you strike the keys on your MIDI keyboard (or equivalent).
• The G-1000 Shapeinator – The G-1000 is a new FX unit that applies customized wave-shaping to your audio. You can wave-shape either using one of the presets, or by creating your own wave-shaping curve.

Here’s an demo of Grain Science 1.3 running on an iPhone:

Grain Science is $9.99 in the App Store.
