    Silk Road is a tangible interface combined with original musical content, suited to concert performance or interactive installation. The interface uses minimal hardware – a single contact microphone – to turn an everyday surface such as a table top into a responsive and user-discoverable performance device. Two principal gestures, RUB and TAP, are derived by feature recognition on the FFT decomposition of the microphone signal. More complex control gestures arise from combinations of the basic pair (Quick rub followed closely by one tap: maximize sustain of sound. Quick tap followed closely by rub: start loop recording (rub to stop & play). Etc). Silk Road began its life as an acousmatic composition, based on instrumental material with overt melody, rhythm, and harmony. The acousmatic work is imbedded in the software realisation (Max, Ableton Live, and Reaktor), and in the choices of gesture mapping, such that the user/player is able to deconstruct and reinvent the musical material. User gestures act as control for the triggering and parametric control of playback and sound transformation on a library of sound clusters derived from the original composition; but this control passes through a stochastic layer so that the system also creates its own variety and a resulting stimulus to the user. Silk Road has been tested with a number of users and has been found to be rewarding both to extended free-form play and to the creation of performances shaped through time. The system has also be tested successfully with different musical source material. Original sound source: https://soundcloud.com/erlc/silk-road

      Maybe I re-invented the wheel but I have been wanting for quite some time to be able to drive particles to the sound of music. So I read up on Fast Fourier Transform, did a couple of false start and finally got something working using Kiss FFT and some Wave Loader code to build a custom ICE Node to do just that. And here is a test scene. The music is by Fool's Chaos - Slowly Falling out of Innocence. Great tune found on Soundscape: http://soundcloud.com/fools-chaos/slowly-falling-d1111 I'm going to post an xsiaddon and the code pretty soon, along with a tutorial here. So stay tuned!

        I've always been fascinated by the patterns that can be created via musical notes. This video is an attempt to visualise a few of them. Each of the nine sections represents a single part in the musical composition. The video was made entirely using Processing, with Virtual Dub and AviSynth used in compositing. All free software - many thanks to the creators. Music is 'Crucible' by Lamarckia. http://soundcloud.com/lamarckia Thanks to Damien Di Fede on GitHub, without whose article on offline FFT, I'd have struggled to produce this.

          3 groups of instruments divided by pitch: 1st group plays tonic G (across spectrum) - 2nd group Bb - 3rd group D. Instruments: strings (dbass - cello - violas - violins), brass (french horn) & wind (english horn) with some variation in playing techniques (trem/pizz/trills...). Rub surface with palm of hand -> Simultaneous trigger & control volume of 24 instrument samples (8 per pitch group). Samples are randomly picked from a sample pool (130 samples). Also randomly set are: Volume min/max - envelope attack - Panning [+LFO]. Tapping -> will also randomise all above parameter but only 1 pitch group at a time. Finally, a random harmonic progression can also be activated. Every time randomness is activated (via Rub or Tap), one pitch group will either move up or down the scale 1/2 tone (to a maximum of 1 tone), or stay put. For example, the reference chord is Gm (G/Bb/D). If the first group (tonic) was to be randomise, that could become Gb/Bb/D or G#/Bb/D.

                  And I'm back! Still playing with my little custom ICE node. Same great tune (Fool's Chaos - Slowly Falling out of innocence - http://soundcloud.com/fools-chaos/slowly-falling-d1111), different set-up: I wanted to use the frequency spectrum to drive strands, so here is the setup: - strands emitted from a sphere - sphere is deformed using a texture map and driven by the 2 lowest frequency bands which pushes the points outward - strands are driven by strands dynamic - in addition each strand randomely listen to a frequency. The higher the input in the frequency, the more the strand is straighten (that is forces a minimum angle between each segment) I've uploaded the scene here: http://www.claudeonthe.net/si/spectro_strands.zip. If you try it, you need 1st to load the WaveToSpectrum plugin using the plug-in manager, the DLL can be downloaded from here (no addon yet, i've add difficulty actually creating it :(, 64bits, win ): https://github.com/claudevervoort-perso/xsi-audio-spectrum/blob/master/WaveToSpectrum.dll

                    Generative AV composition, 2012 Dedicated to 4th Pure Data Convention The visuals consists of the background and figures. Figures are created by and interact with the background - architectural forms of the new building of the Bauhaus University Library (Weimar, Germany). The Fourier resynthesis allows every moving object to create its own frequency band. The work is made in real-time programming environment Pure Data and can be shown either as a video film or as a real-time performance. Project Keywords: Pure Data, GEM, Bauhaus University, spectral music, generative art, real time, OpenGL, Fast Fourier transform, audio processing, audiovisuals.

                      This is something I did with Ryan Pavey about six months ago for my motion class. I need to add credits after the title appears (and maybe change the title, heh), and then finally walk away from this project. Unfortunately I can't find the after effects project file. D'oh! Anyways, hope you enjoy!
