Twkyr: a Multitouch Waveform Looper

Yerkes, Karl and Wright, Matthew

Proceedings of the International Conference on New Interfaces for Musical Expression

Twkyr is a new interface for musical expression that emphasizes realtime manipulation, audification, and visualization of waveforms with a multitouch surface, offering different interactivity at different time scales, within the same waveform. The interactive audiovisual design of Tweakyr is motivated by the need for increased parsimony and transparency in electronic musical instruments and draws from the work of Curtis Roads on time scales as qualitative musical parameters, and Edward Tufte’s “data-ink” principles for the improvement of data graphics.
