APOGEE – Analog Multimode Filter

Unleash a universe of sonic possibilities with the APOGEE, the ultimate Multimode Voltage-Controlled Filter. Designed around the powerful SSI2164 chip, the APOGEE goes beyond conventional filtering, offering a rich palette of sound-shaping tools for your Eurorack setup. From crystalline highs to seismic lows, APOGEE empowers you to sculpt, shape, and transcend the ordinary.

This modular design provides 3 output modes: high-pass, band-pass and low-pass. Additionally, the slope (2-pole or 4-pole) of the band-pass and low-pass outputs are individually switchable making it easy to sculpt your audio signal with precision.

Self-oscillation is available for all output modes transforming your APOGEE into a VCO with the use of the V/OCT input. Unlike many classic 4-pole VCF, the output volume doesn’t drop when resonance is increased. The volume compensation circuit brings a slight tone coloration reminiscent of Japanese classics from the 80s, such as the Roland SH, with a very round and liquid resonance.

Elevate your sound with the Cross-Modulation feature. Let the Band Pass filter dance with the cutoff frequency, unlocking a universe of evolving, organic, and otherworldly tones.
