"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 (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.

Patch Descriptions:

Shapeshifter Chords
Tetrapad - Out 1 (Pitch) to Shapeshifter, Out 8 (Gate) to Quadra 1&2
Quadra - Env1 to QuadVCA, Env2 to Morgasmatron Filter A FM2
Shapeshifter - Chord Mode On (Maj7), OUT to Morgasmatron IN A
Morgasmatron - LP2 Mode On, MIX Out to QuadVCA (In SERIES, but XFADE is fully CCW so only A is heard)
QuadVCA - Out to Springray2 (Large Tank), then to Rainmaker

Dixie II+ Pulse Wave Riff
Metropolis - PITCH to Dixie II+, GATE to Quadra 1&2
Dixie II+ - PULSE Out to Morgasmatron IN A
Dixie II - SINE to Dixie II+ PWM IN (not always active)
Quadra - Env1 to QuadVCA, Env2 to Morgasmatron Filter A FM2
Morgasmatron - Filter A Set to LP2, MIX Out to Quad VCA (In PARALLEL, XFade to A)

Formant Filtering
Dixie II+ - SAW Out to Morgasmatron IN A
Tetrapad - Out 1 (Pitch) to Dixie II+
Quadra - Env1 to QuadVCA, Env2 to Morgasmatron Filter A FM2 (This is normalled to Filter B's FM2, so different modulation amounts can be set with each filter's attenuverter)
Morgasmatron - Filter A&B Set to BP in PARALLEL, MIX Out to QuadVCA

Drum Synthesis

Bass Drum
Quadra - Env1 to Morgasmatron Filter A FM1, Env2 to QuadVCA CV1
Morgasmatron - Out A to QuadVCA In 1, Out B to QuadVCA In 2
(see manual)

Snare Drum
Quadra - Env 3 to Quad VCA CV2
Noise Tools - White Noise to Morgasmatron Filter B FM 1
Morgasmatron - Set to BP, Later a Dixie II Sine Wave is added to Filter B's FM2

Snare Drum 2
Noise Tools - White Noise to Morgasmatron IN B
Quadra - Env1 to Morgasmatron Filter B Q and FM2, Env2 to QuadVCA CV4

Dual Oscillators
Metropolis - PITCH Out to Morgasmatron Filter A 1V/OCT IN, GATE to Quadra Env1
Quadra - Env1 to QuadVCA CV1
Morgasmatron - Filters set to PARALLEL with Maximum Q, MIX Out to Quad VCA
(see manual)

Wet/Dry Tone Blending
Metropolis - PITCH to Dixie II+, GATE to Quadra Env1
Quadra - ENV1 to QuadVCA CV1
Dixie II+ - SINE Out to Morgasmatron IN A
Morgasmatron - Filter A Set to BP, Filter B Set DRY, Filters in PARALLEL, MIX Out to QuadVCA
(see manual)

Tone Shaping In Series
Metropolis - PITCH to Dixie II+, GATE to Quadra Env1
Quadra - ENV1 to QuadVCA CV1
Dixie II+ - SINE Out to Morgasmatron IN A
Morgasmatron - Filter A Set to BP, Filter B Set to LP2, Filters in SERIES, MIX Out to QuadVCA
(see manual)

Ring Modulation
Dixie II - SAW Out to Morgasmatron IN A (This is later switched to SINE)
Dixie II+ - SINE Out to Morgasmatron XFADE In
Metropolis - PITCH to Dixie II 1V/OCT In
Morgasmatron - Filter B PHASE INVERT Engaged, Both Filters Set DRY, MIX Out to main output
(see manual)

Drones
Dixie II+ - PULSE Out to Morgasmatron IN A
Dixie II - TRIANGLE LFO Out to Morgasmatron XFADE In
Dixie II+ - SINE LFO Out to Morgasmatron Filter A FM1
Dixie II+ - SINE LFO Out to Morgasmatron Filter B FM1
Morgasmatron - Filters both set to BP in PARALLEL, MIX Out to QuadVCA
QuadVCA - Out to Springray2 then Rainmaker"
