The Half-Physler is a hybrid acoustic-virtual single reed instrument, where a virtual tube is coupled to a real mouthpiece with a vibrating clarinet reed. We presented this instrument at the NIME 2019 conference in Porto Alegre, Brazil [1].

An opcode implementation of a finite difference viscothermal time-domain model of a tube resonator for wind instrument simulations

Furthermore we presented the resontube opcode for Csound [3], which is running at the core of the Half-Physler and can also be used in any other Csound instruments at the International Csound Conference 2019 in Cagli, Italy.

Live-Performances and Music

Based on the technology of the Half-Physler, two musical pieces were presented at the International Csound Conference 2019 in Cagli, Italy.

Alex Hofmann - 65.4 (2019) - 3’30”

Live electronics including digital processing, embedded systems

Alex Hofmann, halfphysler
Sebastian Schmutzhard, Cello and COSMO live electronics

Shadi Kassaee & Marijana Janevska

Duo for Half-Physler and Alma (2019) - 3’59”
Live electronics

During her Graduate Concert, Marijana Janevska performed an improvisational piece together with Petros Leivadas using her modified version of the Half-Physler [1] and ALMA by Joachim Heintz [2].
