CataRT as an Instrument
Since about 5 years, CataRT is used extensively as a performance instrument by myself and other musicians, and has stabilised and been tried and tested in many performances. This is why the Inventor Composer Coaction call for new instruments was a welcome occasion to present this instrument to a wider audience, and to advance towards a systematic assessment of how to play and compose with CataRT.
To this end, the CataRT as an Instrument page collects the links to sound and video examples demonstrating CataRT as an expressive performance instrument.
Since CataRT must be seen as a whole family of possible instruments, around the core concept of the timbral sound space that is played by navigation, the actual instrument is determined by the controller that steers the navigation.

Outprovisation — Improvisation with Live-Recorded Environmental Sound at ICMC, Huddersfield
ICMC 2011 Late Night Concert 2, Students’ Union, Huddersfield, UK
Outprovisation breaks the tyranny of the instant and fragments the unity of time and place, by improvising with unpredictable live streams from the vicinity of the concert venue: the bar, a park, the street, a shopping mall…
It enlarges at the same time the temporal horizon, the loci of presence, and the sonic space, doubling it by the abstract space of transformed sounds. Read the rest of this entry »
Solo and duo live Performance with Victoria Johnson at Sound of Mu, Oslo, Norway

Alarm–Signal played at Sound and Music Computing Conference, Barcelona
Concert around freesound
Diemo Schwarz performs the piece Alarm–Signal, for CataRT, controllers, and freesound sounds
Alarm sounds and signals are usually lying in wait all around us to alert our attention, warn us of danger, wake us up. This piece finally gives them a chance to express themselves freely, just what the freesound project was intended for.
“Alarm” and “signal” are the search terms used in freesound to find the sounds out of which this piece is exclusively constructed. Despite the startling nature of most of these sounds, the use of corpus-based concatenative synthesis techniques in the CataRT system makes it possible to compose smooth evolutions and soothing combinations of timbres, thereby reflecting on the inner qualities of these sounds that are richer than their everyday use.

Xe-Rocks Installation for Photocopiers and Sound System
Xerocks is an installation by video and sound artist Cécile Babiole designed to turn two copying machines into musical instruments.
Development and adaptation of the real-time sound synthesis system CataRT by Diemo Schwarz for audio analysis and granular (re)composition of the 4 audio channels from the photocopiers by navigation through descriptor space.
