Sunnandaeg

Sunnandæg is a single-voice instrument. One sine oscillator runs through three folding stages, and the end of that chain is wired back into the oscillator's pitch, sync and FM. There is no keyboard and no sequencer. You play it with four XY pads, the camera, and the tilt of the device. Raise the feedback and the folding starts folding itself, and the same gesture stops giving the same answer. SIGNAL Three folding stages: a squaring drive, a triangle wave folder, a full-wave rectifier. Their order can be swapped. A feedback network of three lines, each taking a stage output, the filter, the resonant EQ, or white or pink noise, and sending it back into a folding stage. FILTER Twin Peak — two resonant peaks with their own positions, range and band mode. Push Q far enough and the filter sings on its own. Rez EQ — eight resonators on fixed frequencies from 60 Hz to 9.8 kHz, each driven by…
