This piece was played on the Haken Continuum using Logic Pro's Mainstage application. Mainstage is optimized for real time playing of Audio Unit and Logic virtual instruments. In After Bohéme, four electric piano plugins were used as the sound source, creating 4 voice polyphony. The Continuum allows for shaping of the amplitude envelopes of the sound in such as way that this piano is transformed, suggesting a bowed instrument. A guitar amp simulator was used to create body and subtle distortion to the timbre.
