The Lamda module is an 8-pole (48dB/octave) state variable filter with 2-pole low-pass and 4-pole high-pass modes. One particularly cool aspect of the Lamda is that you can tune resonant peaks above or below the first with the Post Cut control. Put your fine-tuning skills to work in uncovering some of the most heart-stopping synth leads you’ve ever heard.
