This is the third generation of Intellijel's much loved Korgasmatron filter designed in collaboration with David G. Dixon. The Morgasmatron features two completely independent six-mode filters (labelled "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 cut-off, 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.
