Olivella Modular – IMÁGENES – Full DIY Kit

IMÁGENES is a stereo state-variable filter with built-in stereo imaging, panning, distortion, modulation capabilities and plenty of character. Features highpass, bandpass and lowpass modes that are switchable independently per filter, with L & R OUTs straight from the filters themselves for individual/dual mono operation.

The STEREO IMAGE circuit pans the filter’s audio from hard L / R at the knob’s CW position, mono at 12 o’clock, inverted R \ L at its CCW position and everywhere in between, allowing everything from subtle stereo effects and crossfading, to aggressive AM and weird stereo stuff. This circuit comprises of 4 internal VCA’s and is completely independent from the filters.

IMÁGENES has a LINK switch to slave the right side filter cutoff frequency to the left side, which allows for both filters to be controlled simultaneously, either manually or via CV and V/OCT control. Both filter frequencies and image are fully CV controllable up to audio rates, with dedicated attenuverters for all these inputs. IMÁGENES can also self-oscillate cleanly across the audio spectrum and has dedicated V/OCT inputs with good tracking over 5 octaves. This means you can use the module as a dual/stereo sine VCO and it also pings very nicely!

Soft-clipping is applied to the input when going past 12 o’clock on the INPUT LEVEL knob, giving a fatter sound for the filters to chew on. When the DRIVE  switch is engaged the audio input amplitude triples after the soft-clipping stage and right before the filters; this can be used to bring weak signals up to modular level or to overdrive and distort the filters.
