Urphanomen IIb Sasha J.Blondeau

Electroacoustic setup description

All the synthetic sounds of the electroacoustic part of Urphanomen IIB are generated by csound, spatialised with Ircam Spatialisateur (panoramix) around the audience and synchronised with the instrumental part with antescofo.

Transducers inside the instrument are used to project some electronic sounds to the piano table.
