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").

Video: Drancing suit 2002: amplitude (volume) variation of the notes of a triad chord

Scenes

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.

Scenes

Demonstration of the axes of a triaxial accelerometer using sound synthesis. The relationship to gravity is explored using vector acceleration with 3D Variable Frequency Oscillator (VFO) mode, then amplitude variation "triaxial chord" mode.
