Zellen-Linien uses my research on prepared piano and live-electronics I undertook over the past years. I wanted to create an "electronically prepared" piano and there are no physical preparations in the instrument. Since 1999 I experimented with real-time analysis of sounds and with possibilities to control the live-electronics through the gesture of the player. A first result was the composition "Das Bleierne Klavier". Many performances of that piece enriched my experience and led finally to this new work.

technical requirements:

2 microphones (Neumann 184)
8-channel loudspeaker system, sourrounding the public
1 stage monitor
laptop MacBook Pro
soundcard RME Hammerfall + HDSPe Express card
MIDI-sustain pedal
converter sustain-to-MIDI


The signal of both microphones will be used to amplify the piano through speakers 1 and 2. Both microphones are send through Aux 1 and 2 to my sound-card Hammerfall Multiface (symmetrical TRS-connectors).
The 8-channel output of the sound-card (8 symmetrical TRS) will be fed to the console for redistribution over the 8 loudspeakers.
