direct visualization of sound generated by “air to air” setup:

during setup the idea arose to visualize the sound output of the “air to air” modular synthesizer setup, as there was still the video tool sitting in the modular rack.

the sound is influenced by air realted data translated into control-voltages interfering as modifiers of modulation streams.

during tests I realized, that adding some very high frequencies constantly standing, to the realtime controlled sound mix, results in very nice visuals dispersing the waves into point clouds.

so what you see is not exactly what you hear, but not more. only portions of audible signal present in mix are tempered to keep signal in range of screen with / projection width.

finally during performance first only the tv-screen will be operated later on, after adding haze to the room and driving the dust sensor nuts, visualization will add beam projection, which works beautiful with flikering light points and partials of the lines dancing the sound.


air to air wird im Rahmen des g7 OFF am 28.3. 2015 eine Rolle als umgebungs- und interaktions-sensitives sound environment spielen.

Gemeinsam mit anderen Musiker_innen, Performer_innen und allen Anwesenden wird die Raumsituation bezüglich Temperatur, Luftfeuchtigkeit, Staubgehalt und Luftqualität ständig beeinflusst. Alle und Alles im Raum wirkt sich auf die, mit Sensoren überwachten und in die Klangsteuerung des analogen Modular-Synthesizers eingebrachten, jeweils momentanen Zustandswerte aus.

Somit ist ein (steuerbarer) Teil der Klanggestaltung mit “air to air”  abhängig von sich überlagernden einzelnen kumulierten und interagierenden Veränderungen im Luftkörper der Räume des g7, die unvermittelt auftauchen und als Messwerte mit Voltmetern ablesbar sind und gleichzeitig, ja nach Gewichtung der Stärke eines Parameters auch mehr oder weniger deutlich hörbar.

Die akustische Ebene ist allen gleichzeitig aber örtlich unterschiedlich deutlich vernehmbar, die optische Kontroll Monitor Ebene wird nicht oder nur vermittelt, “einweihend” transportiert bzw. zugänglich gemacht.

Erste setup Shots:

Experimental Setup “air to air” environmental / social feedback to sound … shot with GoPro from ceilling – unfortunately bad quality as it was well fitting dark.

pictures, sound and videos taken during the Ars BioArctica Residency with Markus Decker in Kilptisjärvi Biological Research station.

air to air is the working title of the current proejct-derivate from data_opera and even more from its sprout dbd, dusted bass n’ drum

still using analog modular synthesizer controled by control voltages, which are electric displays of sensor values.

what changed is the use of different sensors monitoring air quality, temp and humidity and the approach to go for better focused interactive control.

air-quality sensor turned out to react on smell and does so, if the carrier substance is gone, very delicate and in a very close reach, what offers new approach to use it as interface played with spattels as carrier.

the temperature  and humidity sensors should work good to, if e.g. dancers pass by and stop for a while close to a sensor, while dust sensor and air-quality sensors with damped sensitivity should carry out subtle changes in some general parameters of the sound-environment influenced by the overall cumulated activity while the performance evening.

first two are from preparations for performance at  AMRO 2014 festival nightline in STWST

last is about first steps to engage air-quality sensor as part of an olfactory playable interface to control analog synthesizer parameters. in this case mainly filter parameters.
