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").

Global.pd

Global.pd

The globals are grouped for application across all Drancels, along with RESET (defaults on) and OFF (silent) globals (via message sends), and DSP controls.

WiiOSC.pd

WiiOSC.pd

The accelerometer signals (as well as the button signals, orientation, and position signals) from each WiiTM Remote, are obtained via on OSC dump on a network port (decoupled here as an inlet).

The accelerometer-centric Drancing system currently only uses the (X,Y,Z) acceleration signals, however I am working on exploiting the WiiTM Remote buttons to control various synthesis parameters and modes (they are all already recognised OK as flashing "bangs").

GlobalAM.pd

GlobalAM.pd

The gain and smoothing timescale of the amplitude modulation can be globally controlled across all Drancels.

AMacc3D.pd

AMacc3D.pd

The amplitudes of 3 simple oscillators with "fixed" (yet user-adjustable) frequencies are modulated by the conditioned XYZ Drancel channels. Thus each Drancel can play, for example, a chord triad, or a triad of octaves.

This mode is a bit boring with only 2 s, however the original Drancing sensor suit system with 5 accelerometers gives 5 x 3 = 15 possible fixed notes, which is rich enough for some musical expression. It is a good mode for beginners to get the feel of making music by just waving the hands (or feet).

GlobalScale.pd

GlobalScale.pd

Global setting of the scaling factor for all of the offset acceleration signals.

It should usually be set so that a very strong movement like an air punch does not result in an input to the synthesis elements outside the range -1 .. 1, although for very gentle playing it may be reduced to increase the sensitivity. This can be assessed using the horizontal slider displays and clip warning bangs in Condition.pd, or by using the coloured strip displays of the Drancel GEM monitors.
