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").

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.

Meters.pd.2

Meters.pd.2

Some vertical sliders and some array graphs as meters. These are deliberately not dB VUs, since I am working closely with the linearly scaled acceleration signals.

DSP.pd

DSP.pd

Switches the DSP engine on or off. If it is off you can't hear the audio synthesis. Doh !

Monitor.pd

Monitor.pd

Combines circle and strip/bar monitor visuals for two accelerometer Drancel RGBs.
