    The Studio Electronics ModStar 4075 is a 12hp EuroRack module offering the tone of the ARP 4072 filter with some modern improvements.

    Main Features

    • All analogue Eurorack filter module
    • Offers the classic tone of the ARP 4072 filter
    • 24 dB/octave lowpass ladder filter
    • Go from smooth to seriously aggressive tones
    • 7 patch points


    The 4075 filter is a discrete, voltage controlled, 24/db/oct cascaded transconductance low-pass filter, employing six pairs of hand-matched transistors. In its lowest FREQUENCY setting it shaves off higher frequency harmonics: its RESONANCE or 'Q' circuit pushes those harmonics past the self-oscillation boiling point, projecting a thumpy, thrashing squeal, with explosive low to mid-range power and depth. The design is actually pulled from the four-pole ARP 4072 (better: more parts and trims), without the 12kHz design flaw which hamstrung the original's high end.

    Studio Electronic's 4075 filter is the most requested of the Boomstar filter models, perhaps owing to its uniqueness. Has there ever been a better match for a square wave? It weaves dreams with 'glidey', 70s basslines, is a natural in the lead department, and feels as if a temper tantrum simmers a mere micron beneath its veneer of faux respectability. Aggressive and articulate, this fresh ARP can snap punishing kick drum sounds out as well as colour with bright, edgy, stringy tones for essential arpeggiations.
    Potentiometer Potential
    Three attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, FREQ CV 2, INPUT and OUTPUT, delivering smooth, detailed and complex expression.
    Switch it Up
    Classic Minimoog FULL and HALF strength filter frequency keyboard/voltage tracking for rounder low end with brilliant highs.
    Patch it Up
    Seven patch points: 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT and 2x OUTPUT direct the deepest manipulation.
