Description

IMÁGENES is a stereo state variable filter with lots of character and built-in stereo imaging, panning, distortion and modulation capabilities.

Internally, Imágenes is a dual two-pole filter based on an OTA design with switchable lowpass, bandpass, and highpass modes for each filter. Each side features its own Cutoff Frequency control, but the Link switch allows you to control both sides together if desired.

Input Level with Drive and Resonance are shared controls for both channels, ensuring there’s no undesirable level mismatches. The filters offer their own direct outputs, but Imágenes also features special Stereo Outputs governed by the Stereo Image control, which allows for dynamically panning the left and right channels from full stereo to mono and through to inverted stereo imaging.

IMÁGENES can also self-oscillate cleanly across the audio spectrum featuring dedicated V/OCT inputs and good tracking over 5 octaves, allowing it to be used as a dual/stereo sine VCO or to modulate whatever you want. It also pings very nicely!

Going past 12 o’clock on the INPUT LEVEL knob soft-clipping is applied to the input, giving a fatter sound for the filters to chew on. When DRIVE is engaged the audio input amplitude triples after the soft-clipping stage and right before the filters, bringing weak signals up to modular level or to overdrive and distort the filters.
