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).

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

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.
