DSP Stereo digital oscillator/drone machine + Dual Expander Bundle

Sibilla is a DSP digital stereo oscillator that aims to traslate into music the beauty and harshness of a semi-barren mountain. Its sound is sculpted by various saw and sine waves running through intricate delay networks, altered by LFOs, white noises and creating constructive and destructive interferences.

Both stereo channels are the output stages of two feedback audio loops.

Each loop is made up by a main sub sinusoidal wave oscillator and two saw and sine waves with frequencies affected by the generation of harmonics (right channel) and subharmonics (left channel). All waves have different phases whose offset is constantly affected by minor variations created by two pairs of grains randomly fluctuating within the waves amplitude spectrum and being sampled at a certain speed.

Waves then meet to each other to a common point, together with two white noise sources, creating constructive and destructive interferences constantly affected by two LFOs movements.

Interferences are then run into a resonant low pass filter and then distributed to four different delay lines from which they are fed back into the audio loops at different time intervals depending on the grains movements.

EXP-FX, Il Sole e la Luna (eg. The Sun and the Moon) is an expansion module for Sibilla, aiming to let you admire the same panorama under two different glows.

Depending on the Sibilla uploaded firmware, EXP-FX can either act as an actual Sibilla expander, giving you direct control on more Sibilla’s parameters, or can turn your module into and effect, allowing you to process your favourite oscillator or line instrument the same way Sibilla processes its internal waveforms.

EXP (il Sole)

Expands your Sibilla by giving you more control on the internal AR envelope and filter resonant frequency.

FX (la Luna)

With configurable eurorack/line stereo inputs, turns your Sibilla into an intricate stereo pitch shifting delay effect. Split your incoming sound in two separate pitch shifted tracks whose stereophony is affected by LFOs movements, white noise, delay lines and sampled bits of audio.
