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.

The electronic part is realized as an independent application and doesn’t require a Max/MSP installation.

download electronics for Mac intel – version 1.35 (Max 6 application) – march 2015

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.
