The Intellijel Korgasmatron II represents a significant evolution of a classic topology, delivering dual voltage-controlled filters with substantially more tonal flexibility and aggression than its namesake hardware. As an add-on module for Softube Modular, it functions as two completely independent six-mode filters that can be blended via crossfade, enabling parallel processing workflows within a single interface.
The filter selection spans essential architectures: 1-pole and 2-pole lowpass, 1-pole and 2-pole highpass, 1-pole bandpass, and bandpass reject. This range covers both surgical EQ applications and aggressive resonant sweeps. Critically, the implementation includes overdrive circuitry with input amplification that transitions from clean processing at lower levels to soft clipping around noon, progressing to hard clipping at higher settings. The distinction between soft and hard clipping modes proves particularly valuable when processing complex material like chords, where the nonlinearity becomes sonically pronounced rather than subtle.
Both filters track 1V/oct over 3-4 octaves, positioning the module as a limited oscillator for experimental sound design. The resonance circuitry includes dedicated soft clipping control, allowing independent management of Q-driven feedback saturation. Serial or parallel routing options accommodate different integration approaches within your patch.
The Korgasmatron II's strength lies in its transition from transparent, precise filtering to deliberately destructive tonal manipulation. Rather than presenting a narrow sonic palette, it excels when demands shift between surgical mixing work and aggressive synthesis. This versatility makes it essential for producers seeking character-laden filtering without sacrificing clean utility. It's particularly valuable in modular-based production environments where dual-filter architecture streamlines complex processing chains.
