A whole new way to scratch with MOPHO DJ

Scratching was never pleasant until it became a public display of how well you scratch. Don’t quote me in an explicit way. What I mean by scratching is purely in terms of DJing i.e. able to create one’s own distinctive rhythm.

It all started with vinyl records, and they are almost on their way to oblivion with the rise of digital track commonly knows as MP3/4 records. Then we moved to the digital frontier with new DJ consoles, where the turn tables were able to use the MP3 records i.e. CD. What I learnt is that scratching is limited to circular motion and by using sensors we can easily retrieve the centripetal force and the velocity of the scratch which can be then manipulated to playback the audio. But things just didn’t stop there.

Nicholas Bryan, a graduate who researches music, computing and design at Stanford University, has developed an application that uses an iPod Touch or iPhone’s accelerometer and gyroscope to detect a DJ’s scratching. With this DJs have found a whole new way to scratch, just by placing the device on top of the record to transform the analogue turntables into the digital variety with MOPHO DJ. Using specific software applications and a laptop you can pair the iPhone with the DJ console. Once this setting it done, you are ready to entertain.

As per Bryan,

This new system offers several advantages. Like, it can let the DJ use his old console with little or no modification. A plexiglass disc specially developed by him for this equipment can hold the iphone in place and also an old record thus allowing the turntable to be used for both analog and digital scratching. The system can also use the iPhone screen to display real-time wave form of the audio and apply effects to it.

MOPHO DJ will be reveled at the New Interfaces for Musical Expression conference in Norway at the end of May. This new system will give a whole new dimension to DJing as DJs can forgo their turntables and use the phone for spot “air scratching”.

Bryan is also working on iPhone apps and DJ software which may be released in future.
