CoSiMa participated at the Music Tech Fest in Berlin with a workshop « Hack the Audience » featuring the Soundworks framework. In two days, mai 26 and 27, we developed two performances in which the audience participates with their smartphones : MTF Orgy and GrainField. In both performances, the audience connects their smartphones to the CoSiMa Wi-Fi network and visits a given webpage to participate.
In MTF Orgy, each participant controls the intensity and detuning of two harmonics of a distributed additive synthesizer – the Orgy organ – by tilting their smartphone. The lower harmonics are generated on the PA and the higher ones on the participant’s mobile devices. A musician on stage plays chords on a MIDI keyboard that determine the fundamental frequencies. Other musicians can join the performance. At the MTF performance, we were accompanied by Steve Lawson on the bass.
In GrainField the smartphones enable the participants to play with the granular synthesis of 2 secs of sound recorded from a percussionist sitting in the middle of the audience (see images below). The system records every second 2 secs of sound that are send to the smartphones of the audience so that the sound a participant plays with changes every 8 seconds. The sound generated by the participant’s smartphones can be perceived as a distributed granular echo of the percussionist’s performance without any other amplification.
