Drancing: overview of all videos involving the Drancing accelerometer music system and the Drancel RGB sound and light synthesis atom

Demonstrates combined amplitude (volume) variation, and triggered drum samples ("Drumming by Dancing", "air drums") modes along with Drancel RGB 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").

Demonstrates 2 "Drancer" acceleration avatars, each with 5 Drancel RGB triaxial accelerometer synthesis atoms, with orthogonal "light cones" (which correspond to LEDs with reflectors). The sound here is synthesised from 2 sets of WiiTM Remote accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM. (For this demonstration every Drancel RGB of each Drancer receives the same signals.)

Demonstrates one Drancel RGB accelerometer synthesis atom design, with orthogonal "light cones" (which can correspond to LEDs with reflectors). The sound here is synthesised from WiiTM Remote accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM.

Demonstrates one "Drancer" (an acceleration avatar for the Drancing accelerometer music system) with 5 Drancel RGB accelerometer synthesis atoms (corresponding to hands/wrists, feet/ankles, and waist). The sound here is synthesised from simulated sinusoidal accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM.

Demonstrates two hemispherical Drancel RGB accelerometer synthesis atoms, with orthogonal "light cones" (which can correspond to LEDs with reflectors). The sound here is synthesised from simulated sinusoidal accelerometer signals driving Variable Frequency Oscillators (VFOs) in Pure Data; the visuals are in GEM.

The original "Drumming-by-Dancing" (a.k.a. non-tactile "air drums") mode after which Drancing was named. Drum samples are triggered by conditioned triaxial accelerometer signals driven by free body movement.

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes of notes of fixed (C,E,G) chords at different octaves. When the amplitude varies by small amounts about a larger mean value (such as when waving the arms about a common raised level) the mode can be said to represent Amplitude Modulation (AM).

This is a subtle mode, and care must be taken to sufficiently distinguish the notes of each chord triad. Amplitude variation can also be well combined with other modes such as variation of the frequency of oscillators.
