Borderlands Granular

NEW! Version 2.1 is now available on the as a free update for all existing users! While this is technically a "point" release, it is packed with a ton of new features, bugfixes, and improvements that I have been chipping away at for the past 5 years. Highlights include tempo synced grains via Ableton Link, waterfall-style input and sound on sound recording with an overdub control, semitone pitch tuning, a new ADSR option, proper scaling at all iPad resolutions, and artist presets from Electric Indigo, King Britt, Mikronesia, Tom Hall, and Cristian Vogel. There's a lot more - please have a look at the changelog to see what's new.

Borderlands is a new musical instrument for the iPad.

Explore, touch, and transform sound with this unique interface for granular synthesis, a technique that involves the superposition of small fragments of sound, or grains, to create complex, evolving timbres and textures.

Borderlands emphasizes gestural interaction over knobs and sliders. Create, drag, and throw pulsing collections of grains over a landscape of audio files, or use the built-in accelerometer to sculpt sound with gravity.

Borderlands comes ready to play with default sample content included, but you can load your own sounds too.

“Borderlands has floored us. It is very rare that we find an app that is not only fun to use, but extremely useful. It is truly inspiring. The interface is stunning, the sounds are so evocative: they're a film composer's dream.”
