Review: Ninja Jamm

Become a mixmaster with this must-have app from Ninja Tune, Coldcut and Seeper


We’ve finally managed to tear ourselves away from Ninja Jamm to write this. It’s so hard to put down! Far from being a complete virtual music studio like Stagelight, this innovative remix app still has you mashing up beats, loops and samples. Not only is tapping and swiping involved, you even get to tilt and shake the device!
Ninja Jamm is a collaboration between the Ninja Tune record label, technology collective Seeper and veteran DJ duo Coldcut, who also provide some of the content for remixing. You get to choose from around 35 tunes (by Ninja Tune artists) and sample packs, some of them free, including genres such as dubstep, house and trap. The ‘Jamm’ then starts playing and you can skip to different song sections and loop them indefinitely. The default screen sees you switching between eight loops for each of the four channels. Flicking a channel to drill mode lets you hold down one or more individual waveform clips to play them repeatedly and create custom loops. A stab matrix with slider is used to add scratch samples, while the effects screen offers crush, filter, delay and reverb for each channel. Even better, an XY pad enables you to apply multi-effects by moving two grid markers or tilting the screen. Finally, the Coldcutter automatically cuts up clips in various ways, with extra buttons for manual fills and glitches – or just shake the device.
While there’s sadly no option yet to import your own samples – which would hugely expand the creative options here – mixing is addictively fun, and you can even record your Jamm and upload it to SoundCloud. If you own a tablet, it’s also well worth paying £0.99/$1.49 for the Share+ IAP which also gives you access to all of the tools on a single screen, an Android exclusive, to make mixing even easier.
