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").

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.

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.
