PushPull


PushPull is the first instrument prototype created as part of the 3DMIN project. Central control element is a bellow combining inertial sensor data with mechano-analog sound input and digital synthesis. Referring in it’s exterior appearance to traditional instruments like the accordion as well as to a blacksmith’s bellow we aimed to establish an interface triggering imagination and engagement of both, the musician and the audience, a tangible object enabling a physical relation to the created sound. We think that in the characteristic air movement, the affordances offered by the object itself, the combination of complex algorithmic structures and physical constraints lays a compelling quality of expression. Within a performance with PushPull, it is possible to combine chaotic elements as well as rhythmical patterns, while shifting between audio feedback and harmonic structures. The ensemble performed within Europe and internationally: Atlanta, Georgia (3rd place at Guthman Competition, March 2015), Amsterdam (Modality Meeting, OT301, April 2014), Berlin (Roter Salon, Juli 2014), Athens (ICMC, September 2014) and Lissabon (ICLI, November 2014).


Balgerei is a performance with three similar instruments called PushPull. Central control element is a bellow combining inertial sensor data with mechano-analog sound input and digital synthesis. During the performance the trio touches chaotic elements as well as rhythmical patterns, while shifting between audio feedback and harmonic structures.

Moving the hand piece activates the bellow. Hand movements restricted by the limitations of the bellow turn into gestures and create air flow over a microphone. Inertial sensors in the hand piece together with a thumb stick allow for continuous sound shaping, while four buttons complete the setup to trigger changes or change between synthesis engines.

Referring in its exteriour appearance to traditional instruments like the accordion as well as to a blacksmith’s bellow we aimed to establish an interface triggering imagination and engagement of both, the musician and the audience, a tangible object enabling a physical relation to the

created sound and necessitating a set of movement patterns1. We think that in the characteristic air movement and the affordances offered by the object itself lies a compelling quality of expression, which was also observed by the makers of more recent electronical instruments like the accordiatron (M. Gurevich & S. Von Muehlen) or the squeezevox [sic] (P. Cook & C. Leder, both 2000).
