Twkyr: a Multitouch Waveform Looper
Karl Yerkes, Matthew Wright · 2014
Twkyr is a new interface for musical expression that empha-sizes realtime manipulation, audification, and visualization of waveforms with a multitouch display, offering different interactivity at different time scales, within the same wave-form. The interactive audiovisual design of Twkyr is moti-vated by the need for increased parsimony and transparency in electronic musical instruments and draws from the 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.
