Scenes

Demonstrates combined oscillator frequency variation, amplitude variation, and triggered Drum sample ("Drumming by Dancing") modes along with Drancel RGB 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

Demonstrates two hemispherical Drancel RGB virtual accelerometer synthesis atoms, with orthogonal "light cones" (which correspond to LEDs with reflectors). The sound here is synthesised from Wiimote signals driving 3 Variable Frequency Oscillators (VFOs) per Drancel RGB in Pure Data; the visuals are in GEM.

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.

Scenes

A minimal example of Drancel RGB 2D visuals. The colour of the central circle is an average over the RGB colours corresponding to the XYZ axes of a triaxial accelerometer. Driven by a WiiTM Remote as wireless accelerometer signal source.

Scenes

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.)

Download and install the DranceWare PureData/GEM prototype for Wiimote on Mac OS-X

Download the attached DranceWare PureData/GEM prototype for Wiimote and unpack.

Note that it is marked as a PROTOTYPE - not even "alpha" software - with the support that implies, i.e. none at all.
You are however welcome to report problems and/or successes via the feedback form.

The bundle includes a subdirectory of free drum samples from Audio Pervert. (I hope this is ok concerning copyright, future versions of PureData will probably only used synthetic drums anyway.) There are also some test files which you can safely ignore, and next to no help, because it is a prototype.

If you select Drancing.pd in the Finder it should either launch PD-extended or give you the option of selecting PD-extended as the default app for this kind of file, and then launch. The 0th level Drancing.pd wrapper for the DranceWare.pd GUI skin should be visible:

Make sure the DSP is ON (use either the button/bang in the globals panel at the top of DranceWare.pd or use the PD Media>audio on menu item). You should also perform the PD Audio Test.

WARNING: set your speakers/headphones to a safe, relatively soft level at first;
if you make a mistake the sounds can be quite penetrating and loud, especially with VFO on !

Obtain 2 Wii Remotes

Keywords:

You can buy Nintendo WiiTM Remote units (a.k.a. "wiimotes") at nearly any electronics, gaming, or department store. (I found EB Games here in Sydney at Westfield, Bondi Junction, very helpful. They also advised me well to get a 2-Wiimote charging unit with rechargeable battery pairs in a small cartridge cleverly designed to fit into the Wiimote.)

You don't need the Wii console, and you don't need the "nunchuk" controller extension.
You don't need the Wii position sensor bar; we'll only be working with the triaxial accelerometer signals from each Wiimote.
DO read the safety instructions from Nintendo and DO always wear the strap for your Wiimote.
