With the ’Uhane Wave Slide, a new digital musical instrument has been created that is based on the playing principle of a lap steel guitar, but ex- pands and modifies it. The instrument has an electric circuit and through the feedback of magnetic fields its strings can be made to vibrate permanently without striking them. The string vi- bration recorded with a piezo bridge pickup is analysed in a Bela microcon- troller in real-time and the frequency and the course of the amplitude are continuously determined. Two sound generators are available to the user, which can be individually mixed with the output signal and transposed oc- tave by octave with the help of various faders. For playful interaction, the in- strument has potentiometer-controlled filters and effects as well as an infrared distance sensor with which the master output volume can be played without contact, similar to a theremin.
