This is the third generation of Intellijel’s much loved Korgasmatron filter designed in collaboration with David G. Dixon. For obvious reasons, we considered naming it the Korgasmatron III. But once we experienced the purity and range of its finely re-tuned filters; the warmth of its soft-clipping; the beefiness of its Q-DRIVE; the aggressive howl of its all new overdrive circuit; the additional XFADE options; and its clangorous new ring modulation capabilities, we knew it was something much more than a Korgasmatron III. It was a MORgasmatron!

The Morgasmatron features two completely independent six-mode filters (labeled “A” and “B”) — each with its own mode-select knob, input, output, cutoff, resonance, Q-drive and gain control. Each filter has a pair of CV inputs (one with a built-in attenuator and the other with a built-in attenuverter) for modulating cutoff, and another CV input for modulating resonance. Both filters self-oscillate at maximum Q, and produce pitched sine waves that track the two separate 1V/OCT inputs.

You can use the two filters independently of one another, or you can use them together (in either a series or parallel connection) and smoothly crossfade between them using either the XFADE knob or the XFADE CV input and built-in attenuverter. You can flip the DRY switches to instantly bypass either or both filters; invert the phase of Filter B; or overdrive Filter A by switching on the new Overdrive circuit. A MIX output provides (as you might suspect) a mixed output of the two filters.
