Pure Data example: The Ethical eMarket logo animation

The Ethical eMarket logo was animated by Webel using the GEM visual synthesis extensions for the PureData synthesis environment:

Global.pd

Global.pd

The globals are grouped for application across all Drancels, along with RESET (defaults on) and OFF (silent) globals (via message sends), and DSP controls.

WiiOSC.pd

WiiOSC.pd

The accelerometer signals (as well as the button signals, orientation, and position signals) from each WiiTM Remote, are obtained via on OSC dump on a network port (decoupled here as an inlet).

The accelerometer-centric Drancing system currently only uses the (X,Y,Z) acceleration signals, however I am working on exploiting the WiiTM Remote buttons to control various synthesis parameters and modes (they are all already recognised OK as flashing "bangs").

AMacc3D.pd

The amplitudes of 3 simple oscillators with "fixed" (yet user-adjustable) frequencies are modulated by the conditioned XYZ Drancel channels. Thus each Drancel can play, for example, a chord triad, or a triad of octaves.

This mode is a bit boring with only 2 s, however the original Drancing sensor suit system with 5 accelerometers gives 5 x 3 = 15 possible fixed notes, which is rich enough for some musical expression. It is a good mode for beginners to get the feel of making music by just waving the hands (or feet).

GlobalAM.pd

The gain and smoothing timescale of the amplitude modulation can be globally controlled across all Drancels.

Drancel RGB PureData/GEM accelerometer monitors

Drancel RGB PureData/GEM accelerometer monitors

The Drancel accelerometer "light atom" principle can be applied to any light source or video generator; here PureData/GEM computer visuals are used to create Drancel accelerometer monitors, based almost exactly on the Java visuals from previous versions of DranceWare.

The corresponding (very pragmatically developed) prototype PureData/GEM patches look a bit rough, however the resulting monitor lights are beautiful when projected behind a performer, and they provide excellent visual feedback to accompany the audio synthesis.
