Video: YouTube: Drancing accelerometer music with Wiimotes: 3D variable frequency oscillators + amplitude variation + triggered "air drum" samples

Scenes

Demonstrates combined oscillator frequency variation, amplitude variation, and triggered Drum sample ("Drumming by Dancing") modes along with DrancelRGB monitor visuals projected onto the "Drancer" performer.

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").

Scenes

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes and the frequencies of 5 x 3 = 15 pure sinusoidal oscillators.

One can hear "beat" frequencies generated by similar frequencies corresponding to different accelerometer channels, such as when the arms are raised to similar levels, which effect can be exploited for musical nuance and for movement therapy to measure symmetry of posture.

I present here, as adapted Unified Modeling Language (UML)TM structure diagrams, a simplified model of the hardware, data acquisition, and JSyn audio synthesis circuits of an earlier version of DranceWare for Drancing.

PureData/GEM

in

$dr$ of Webel is a Pure Data (PD) enthusiast. A PureData-based audio synthesis version of the DranceWare software for The Drancing accelerometer music "air instrument" uses GEM to synthesis rich visuals in real-time from accelerometer signals (such as WiiTM Remote signals), synchronised with the accelerometer music. The PLAY music project "sound circles" animated logo is synthesised using PureData/GEM, as described in this mini-tutorial

In 1998 I was kindly invited to DIEM in Arhus in Denmark by then director Wayne Siegel to discuss the Drancing accelerometer music air instrument and to learn about DIEM's bending sensor air instrument.

A Webel zone dedicated to synthesis technologies. A good place to start is this fun tutorial with step-by-step PureData patches and videos of synthesised sound and visuals:

DranceWare: software for Drancing

The DranceWare synthesis and control software has gone through an evolution since 1996 through MIDI triggering and modulation driven by low-level C code, to C++ in 1999, then to Java in 2001, then to full real-time synthesis in 2002 using JSyn audio synthesis and Java3D/Swing visuals, and since 2008 there is a PureData/GEM patch-based version (similar to MAX/MSP). All Drancing software and systems development is strongly model-driven using UMLTM and SysML.
