More turntable research.


Datasound from Troika offers an alternative and more sensual interpretation of electronic data by exploring their musical potential. Datasound is a fully functional musical instrument that enables you to hear, mix, scratch and perform digital data signals, from a picture, an old program floppy, a computer virus, a love letter, or a drawing.

On the right side of the deck stands a turntable that plays 5.25inch floppy disks.The datasound mixing deck is completed with a sampler that reproduces in real time samples obtained from a variety of objects that contain or generate data: a Winchester hard drive, a neon light, a 3.5inch floppy disk drive, a flatbed scanner, data cartriges, travel cards.

More turntable research.


Audio-Visual-Disk-Jockey vinyl turntable (AVDJ Deck) from 3eyes (former RCA students) is a device that allows you to scratch video and audio media using a normal turntable and unmodified record.

“The AVDJ deck is in fact a steel deck plate that can be fitted to any Technics 1200 or 1210 turntable in less than 10 seconds, – the 1200 and 1210 being the ubiquitous, industry standard deck found in literally all clubs”.

Looking at the videos, they appear to be using an optical sensor (maybe from a hacked mouse). This is an approach that VScratch also used. Putting the sensor on the end of an arm though is a nice touch. It does appear that using an optical mouse has quite a bit of latency between the scratching and response. Does anyone else have any experience of this?

V-Scratch by Valerio Spoletini is a software environment which allows for unique visual interpretations in turntable composition. It transposes aural nuances made by the rotation of the record: the variations of speed, audio spectrum and volume. In addition to the sonic aspects (volume and frequencies), the physical act of spinning the record back and forth is transmitted through an optical mouse. All these variables enable a simultaneous performance of moving image and sound while creating an infinite space for possible results.

spinCycle, colour tracking turntable


A project in a similar concept to RGB Player is spinCycle from Spencer Kiser (an NYU ITP student).

As the turntable rotates, a camera reads the fluorescent tinted plexiglass (red, yellow and blue). The camera acts as the input detection, picking up the colours and positions of the pucks, but also as the visual feedback for the audience (displayed behind the performer). The speed of the turntable can be adjusted, as well as which colours are being detected. Whilst the input remains the same, experiments in using it as a drum machine and granular synthesis have been tried by Spencer.

Visual Scratch

Visual Scratch

Visual Scratch by Jesse Kriss is a realtime visualization of scratch DJ performance. Ms Pinky is used to get the velocity of the turntable into Max/MSP using a control record. Ms Pinky allows you to scratch an MP3, so the sound is routed out to the mixer, and then back into Max where volume & frequencies are analyzed. A second machine is used to output the Processing visuals. Jesse has previously created MaxLink, a method of communication between Max/MSP & Processing, used in the project Visual Scratch.

RGB Player

[update] a video is now online.

RGB Player

RGB Player by Toke Barter, is a cylinder-shaped musical instrument with a built in scanner and a mounted rotating disc. The ‘instrument’ is played by placing coloured objects (childrens toys) onto the surface of the rotating glass disc.

As an object passes over the scanner beneath the disc and its colour values are sampled, sound is generated in response to these colours and the object’s distance from the centre. The closer to the centre an object is situated – the higher the pitch achieved. Once a pattern of objects is created on the disc, a musical pattern emerges – where adding or removing objects will change the nature of the performance. The diagram below shows how the rgb value of an object determins the sound sample instrument.

RGB Player won 2nd prize Helen Hamlyn Future Selves and The Thames & Hudson and RCA Society Art Book Prize. Toke is part of London based Radarstation.
