The Dark Synth is an additive synthesizer with some unique characteristics. You can define a waveform of up to 2048 partials (sine waves) for its main oscillator, the ADDITIVE oscillator, using presets waveforms, spectral processing algorithms and freehand drawing. Moreover you can add up to 128 copies of the Additive oscillator, and each copy (generator) can be detuned and phase-shifted with respect to the others.
Percussa created an FM synthesizer for the AudioCubes in max/msp.
This instrument was created as part of our latest interactive dance spectacle “Absorbe-moi” The starting idea was to create an instrument dealing with sound synthesis and reacting directly with the movement of the 2 dancers. Their movement is tracked live and analyzed by another computer, collecting the main characteristics of it (X position, Y position, Height, Width, X gravity, Y gravity, speed and luminosity). This continuous flux of data is smoothed, then transmitted as normalized data into the synth trough 8 channels, used to modulate the main parameter of the sound, like the oscillators frequency, the filters cutoff frequency, their resonance, etc..., or used to control events like the retriggering of envelopes, zeroing the oscillator phase, modifying their wave shape, controlling the rate of the sequencers, or the spatial position of the sound sources in the set (a quadriphonic system is used here).
