( AMicroscope Performance )

 

 

 

LU.KI.DUS. is a live cinema and sound performance focusing on scale, pattern, and awareness. We developed a technique to automate a microscope’s stage position through computer controlled motors. Our goals revolve around exposing the unseen yet omnipresent events which unfold at the microscopic scale. We will be crafting a distinctive kind of microscopic world that leans more towards the experimental rather than scientific.

Using different combinations of crystals, contaminated water and alcohol, we set ourselves on a journey to find the unknown. The audience is invited to witness this journey. Few rehearsals took place. We were presenting to the public live matter / life, and nobody can rehearse for life.

THE MICROSCOPE PLATFORM

 

 
 

To achieve a cinematic effect and reduce vibration caused by hand movement, a 3D printed platform was designed. Both axis (X and Y) of the microscope are controlled by stepper motors. Kurt Kaminski's previous Houdini experience – back at Dreamworks – come into play to model the platform. Akshay Cadambi calculated the exact rotation needed for the gears.

 

 
 

 

 

IMAGES FOR DISTORTION

 

 

 

 

A Processing code captured the live feed from the microscope. Before displaying it on the big screen, it applied basic mirroring effects and slight code distortions. These distortion were applied at discretion during the concert.

 

 
 
THE MUSIC
 

 

A 15 minute electronic music soundtrack was written for the live visual content. The soundtrack is composed of five different movements (as seen on the sketch above):

1. Opening
2. Caffeine
3. Acrylic
4. Crystals
5. Spring hommage

It featured -mainly-: droning sounds, atmospheres, and medium to high pitched sequences. Both the wave equation and acoustic vibration principles seen in class, were implemented to generate the inputs of these sequences.

A. Graphic Output of wave equation images were taken as the source to generate some of the sequences.
This values were saves as a TXT file.

 


B This numbers were thenused as sequence INPUTS in SuperCollider (Important note: this data was to be plugged into different \synths. This increased our possibilities of composing a sound piece, since the exact same numbers could generate different tonalities and timbres when connected to different instruments \synths. This would also mean we would get different results other than white noise).

An example of a synth is screen-captured below.

C. SuperCollider reads the file, and then controls timing and sequence repetitions (loops) of the piece (in order for them not to play at the same time).

An example of the above in the following image. The first sequence of code, reads the TXT file and stores it as an Array. All of the frequencies are stored in the first position of a nested array.

In the highlited section of the code, a sample Routine that shows how the data is actually inserted into one /synth. In the example a Gendy Unit Generator (with samples below).

 

 
 

D. Finally, all the data was sent to Logic X which equalized, compressed and fine tuned the sounds for live performance (reverberations and slight distortionswere also applied at this stage). Total sound channels used: 18 and 4 buses. For live performance, the file was re-configured from Stereo to Surround (DST 7)*

* Notice the sound spatialization on each track.

DETAILED SOUND EXAMPLES

 

FOREST SOUNDS

Modified in Logic X with a Flanger, Reverberation and Compression/EQ. These sounds are used to create an atmosphere before the Electronic part.

To avoid a complete randomized result a % (modulo) is used.



TUBULAR BELLS (GBMAN.ar)

A linear-interpolating sound generator based on the equations above. Used for the creation of a semi-random melody. This melody can be heard during the climax of the piece.

 

OPENING GENDYS

A dynamic stochastic synthesis generator
conceived by Iannis Xenakis. Three frequencies are given to each Gendy trigger. In this case, the data from the



ESPUMA (FOAM)

The bitmap data is used to generate noise. The values are inserted into the trigger of an impulse. These sounds are wave/ocean like. They are used as a transition after the opening and as a passage separation in them iddle of the electronic part (Crystals).

FINAL RESULTS

 

 

Here is a diagram of the specific places within the composition where this sounds are placed. To notice: the opening, the dust, tubular bells and white noise waves.
