What is Drancing ?

Drancing is a gestural synthesis accelerometer music system (an "air instrument") under development by Dr Darren Kelly since 1996. Drancing employs triaxial-accelerometers (3D vector acceleration transducers) to synthesise music, visuals, and computer controls from human gestures, dance, and movement.

The name Drancing is derived from "Drumming-by-Dancing" (or "air drums" mode) which is just one of its many applications. It can also be used as an "air synthesizer", "air guitar", or "air piano", and to make sounds never heard or named before.

Demonstrates combined amplitude (volume) variation, and triggered drum samples ("Drumming by Dancing", "air drums") modes along with DrancelRGB monitor visuals projected onto the "Drancer" performer. Includes stereo echo with constant timescale and some feedback.

For this demonstration two hand-held WiiTM Remotes on a MacBook Pro were used. (The original Drancing accelerometer suit (since 1997) used 5 triaxial accelerometers in a "body star" pattern").

GlobalTrig.pd.2

Global setting of the trigger threshold (and RESET/OFF switches). It can be useful to tune the threshold across all Drancels equally when the accelerometers are all worn/held in a similar location (like all hands), however when they are worn on - for example - both the hands and feet the thresholds need to be separately tuned.
