Whimsical Raps Atrium

Atrium is a new instrument where playful gestures meet dynamic systems.

Five voices of analogue synthesis, controlled and modulated polytimbrally. we’ve taken ideas from our decade of modular exploration, and rethought how we reach into polyphony.

Each voice is shaped by its harmonic energy while three core timbre modes push into richer territory. from simple suboctave and noise waves, through frequency modulation, and landing in formant synthesis reimagined. all squeezed through a lowpass/gate combination, providing balance and occasionally emphasis.

No digital multi-effects here, just spectres in the machine. a novel configuration of three filters, two delays, and feedback. front and almost centre — this resonant body is meant to be played. sequenceable, modulatable, while feeding back not just sound, but shape for unfolding cybernetics.

And to modulate! everything mappable to everything else, tactile input extended on the fly, mapping as a performance in itself. sources are dynamically phased across voices, and stretched in relative duration. gestures captured into five recorders, extending play rather than overriding it, all twisted in time at your whim.

Atrium is deeply learnable, and for those moments of quick change, instantly recallable. extensible with usb and midi and cv input.
