Abstract
The Uhane Wave Slide is a new digital musical instrument inspired by the lap steel guitar, which is typically played horizontally with a slide. It extends this playing approach by using magnetic feedback to keep the strings vibrating continuously without being plucked. The string vibrations are captured by a piezo bridge pickup and analyzed in real time by a Bela microcontroller (a small embedded computer), which continuously tracks frequency (pitch) and the amplitude envelope (loudness over time). The player has two sound generators that can be mixed with the output signal and shifted up or down in octave steps using faders (sliders). For expressive, playful control, the instrument includes potentiometer-controlled filters and effects, as well as an infrared distance sensor that lets you shape the master output volume without touch—similar to a theremin.
Uhane Wave Slide er et nyt digitalt musikinstrument inspireret af lap steel-guitaren, som typisk spilles vandret med en slide. Instrumentet udvider denne spillemåde ved at bruge magnetisk feedback, så strengene kan holdes i vedvarende svingning uden at blive anslået. Strengenes svingninger opfanges med en piezo-bro-pickup og analyseres i realtid i en Bela-mikrocontroller (en lille indbygget computer), som løbende bestemmer frekvensen (tonehøjden) og amplitudeforløbet (styrken over tid). Brugeren har to lydgeneratorer til rådighed, der kan blandes individuelt med udgangssignalet og forskydes op eller ned i oktavtrin ved hjælp af faders (skydeknapper). Til legende og udtryksfuld kontrol har instrumentet potentiometerstyrede filtre og effekter samt en infrarød afstandssensor, der gør det muligt at styre master-udgangsvolumen uden berøring – i stil med en theremin.
