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:

Filters.pd

Filters.pd

Some of the very electronic noises generated can be a bit abrasive, especially from wide-sweeping VFOs, so it is useful to cut some very low rumble and some very high frequencies. This patch feeds stereo to some basic mono filters in FilterCh.pd.

VFOacc3D.pd

VFOacc3D.pd

Variable Frequency Oscillators (VFOs) are grouped in a triad corresponding to the (X,Y,Z) accelerometer channels of a Drancel.

This is the most immediately powerful Drancing mode as far as aural biofeedback is concerned, and it promotes proprioception. It sounds quite sci-fi like and eerie, and reminds one of the Theremin, except there are (in the mode shown here) 3 independent frequencies, which can be made "rub" together to create beat frequencies.

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

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).
