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").

AccWavetable2x3.pd

AccWavetable2x3.pd

Experimental wavetable mode, where the wavetable is defined by 2 triaxial accelerometers. Tends to crackle, not recommended, although the basic idea shows potential, and the generated sound is interesting. Might work better with 5 triaxial accelerometers and some smoothing.

GlobalTrig.pd.2

GlobalTrig.pd.2

Global setting of the trigger threshold (and RESET/OFF switches). It can be useful to tune the threshold across all Drancels equally when the accelerometers are all worn/held in a similar location (like all hands), however when they are worn on - for example - both the hands and feet the thresholds need to be separately tuned.

Circles.pd

Circles.pd

Generates the 4 circles in the Drancel RGB PureData/GEM accelerometer monitors. The central circle is the simple additive colour derived from the (R,G,B) values corresponding to the (X,Y,Z) accelerometer signals.

GlobalVFO.pd

GlobalVFO.pd

The variable frequency oscillators can be globally controlled across all Drancels.

Condition.pd

Condition.pd

Before sensible synthesis can occur each accelerometer Drancel must by calibrated, or "homed". This calibration value is then applied as an offset to condition the Drancel.

The homing process is a crucial principle in Drancing, as it defines a point of "silence and darkness" for the "drancing" performer, and promotes body awareness. The "homing" can take place at any accelerometer orientation (as long as the accelerometers are held still for the brief period of calibration, typically 1 second).

The signals are also scaled linearly, and then clipped to within -1..1 range.
