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.

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.

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.
