Borderlands Granular is a new musical instrument that enables people of all ages to touch, transform, and explore sound. Simply double tap to begin!

“The best app for exploring sound just got better... This is 'go out and buy an iPad to run it' good stuff.“ -Peter Kirn, Create Digital Music

“When I first saw the demo video for Borderlands Granular in 2012, my jaw hit the floor. My first thought was ‘THIS is what making music on an iPad should be.’”
Sean Garland, iOSMars.com

“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.”
Paul Hepker and Mark Kilian, Film Composers (Tsotsi, Eye in the Sky)

“It’s beautiful, it’s absolutely great. It goes in a completely new direction."
Christian Fennesz, Experimental Musician. Interview from Tiny Mix Tapes, May 2014

Borderlands Granular uses a technique called granular synthesis, which involves the superposition of tiny fragments of sound, or “grains," to create complex, evolving timbres and textures. The app is designed to be easy to use, emphasizing gestural interaction over knobs and sliders. Create, drag, and throw pulsing clouds of grains over a landscape of audio files, or use the built-in accelerometer to sculpt sound with gravity. Simply double tap to begin!

Borderlands comes ready to play with default sample content included, but you can also load and export your own sounds via Audiobus, Audioshare, and real time input from the mic or external audio interfaces. Re-sample recordings made within the app on-the-fly for layers-upon-layers of granulation.

You can also improvise alongside the app - touches and parameters may be recorded, looped, stored, and duplicated. Entire configurations of clouds, sounds, and automation can be saved into presets, or “scenes,” that may be recalled at a later time, allowing Borderlands to seamlessly transition between the studio and the stage.

True touchscreen instrument

A steal at any price, and a touchscreen legend.

Borderlands was the first app - and still the most unique IMO - that really took the touchscreen concept and its capabilities and transformed the iPad into an actual musical instrument. I jumped on board v1.0 in 2012 and never looked back.

A bit of history - in 2012 the very new community of iPad musicians totally fell for this app, and when it became apparent that real life had slowed the apps development after its initial release, the community of Borderlands users not only maintained their enthusiasm but also continued to grow the user base despite the "advanced beta" characteristics of v1.0. It reached legendary status as the oldest app in the App Store that you absolutely could not do without, and every iOS update would be quickly followed by a chorus of "yeah OK but does Borderlands still work on it?"

When the update dropped years later, minds were blown everywhere. As the greatest iOS app ever to be rescued from history by its own developer, even an Alchemy iOS update would not touch this - as great a synth as it is, Borderlands was pioneering AND legendary AND is still the most unique instrument on a touchscreen. Bar none.

Thanks so much for the incredibly kind review and for supporting the app!

Great app but with frustrating file management

Borderlands is a great granular synthesizer.
But given that it's entire purpose is to work with samples, the sample management options are frustratingly limited.
In order to load a sample or save a recording from within Borderlands, one must use AudioShare, an additional $5 app.
Thankfully Borderlands does support AudioBus, but that's quite a roundabout approach, because it requires a sample playback app, routed into borderlands for recording, then yet another app for recording the output from borderlands yet again. This is not ideal when working with long samples, nor is it ideal given notoriously unstable iOS app reliability when working with large samples in small device memory capacities, nor is it ideal when there may be any number of different sample rates or bit-depths between apps, resulting in questionable audio quality.
Supporting an industry standard file management solution like Dropbox or even the freely available (and industry standard to a lesser extent) AudioCopy would cure a major headache.

Developer Response ,

Thanks for your feedback (and apologies for the very, very delayed response). I am still working on the app (it's a side project amidst other work and family commitments, so the timeline is slow). Looking to support Dropbox and the new Files api asap. I went with Audioshare for Version 2 at the advice of the iOS music community since Audioshare is the standard swiss army knife for file management on iOS.

Hope you're still able to get some use out of the app regardless.

Very best,

Sound Design Secret Weapon

I’ve been hesitating to write a review because it will be my not-so-secret weapon now, but I’ve been able to create a lot of very useful material with this app. I’ve been creating sound for video, stage, and environmental applications, and I’m always surprised how I’m able to generate fresh new sounds from any recordings I put into the app. Once you get the hang of the workflow with Audioshare, it’s a snap to get the output up to Dropbox (or elsewhere) and over to my laptop or other devices. I hope they keep updating this app. Adding some nice reverb, delay, and compression effects would be great.
