Puremagnetik Clap Box iOS App

Tablet based music production might be yet to come of age, but Clap Box is a fun way to add value to your iPhone, iPod Touch, or iPad in the context of making music at home…


The Simmons Clap Trap is a classic analogue clap synth that can simulate a single clap (or at least a couple right on top of each other), an auditorium full of them, or anything in between – and it can do it with somewhat convincing realism or to spacey effect. Puremagnetik have created a like for like recreation of the old box on iOS, with the buttons and dials all replicated  in the same design as the original analogue version (the digital remake is more common, certainly on YouTube). And it sounds really good!

The decay length and pitch of the original clap sound can be tweaked, and the pitch and number of claps – as well as the uniformity of their timing – can be played with too. Balance between the initial sound and the delay to taste, and voila: a clap to sample, trigger, or even to keep time for you from 1-300BPM. There’s even a tone slider instead of the original’s volume, and if anything’s not clear you can press a button and tooltip style descriptions jump onscreen.

As mentioned, Clap Box can be triggered manually by an on screen button, via MIDI (with selectable channel), or by listening for a sound input at varying sensitivities. The only output is direct, and whilst Clap Box being free (at review) totally mitigates that it’s exactly the kind of app that I’d have no qualms about paying 69p for to utilise the iOS Audio Copy/Paste functionality. It seems that iOS music apps are either quite expensive and full featured or feel like cynical cash ins based on ‘novelty value’ – so we’ll wrap up with a round of applause (groan) for Puremagnetik for making Clap Box free, and a request from OD to app developers to increase the fun potential of iOS music making with simple, cheap apps that create cool sounds that can be easily sampled into the ‘big boys’.

We’re not 100% sure whether it’s fair to give an OD score to free and very low cost apps, even if we do want to review it so you guys hear about it. We’ve left it off here, because at the princely sum of zero pence it doesn’t really seem like we can be objective; so much of our score comes down to cost/value that it doesn’t make much sense and also makes our ‘pro’ scores seem less relevant. Any thoughts let us know!
