Hexinverter Red Dragon
COLOUR…TONE…CHARACTER…
12 HP Eurorack module
A four-pole resonant low-pass filter with a Soviet-era core and continuously variable 6 dB to 24 dB slope.
Features
- Voltage-controlled resonance.
- Resonance can self-oscillate, with clipping available to tame extreme feedback.
- Built-in post-filter VCA that can be disabled.
- Continuously morphs between 6 dB and 24 dB filter slopes.
- Input-stage core overdrive reaches full saturation.
Controls & Jacks (19)
- Output VCA— On fully opens the built-in VCA for standalone-filter use; off enables VCA control from the VCA CV input.
- Resonance Clip— When on, clips resonance feedback at extreme settings for a tamer resonance tone.
- Morph CV— Control-voltage input for the filter-slope morph parameter.
- Drive CV Amount— Bipolar attenuverter for the Drive CV input.
- Input Drive— Sets input-stage core overdrive, from normal level to full saturation.
- Cutoff— Sets the filter cutoff frequency.
- Audio Out— Filtered audio output.
- Drive CV— Control-voltage input for input-drive saturation.
- Morph CV Amount— Bipolar attenuverter for the Morph CV input.
- Morph— Morphs continuously between 6 dB and 24 dB filter slopes.
- Resonance CV Amount— Bipolar attenuverter for the Resonance CV input.
- Resonance— Sets the filter resonance, which is capable of self-oscillation.
- Cutoff CV A Amount— Bipolar attenuverter for the Cutoff CV A input.
- Cutoff CV B— Additional cutoff CV input.
- Input— Audio input to the filter and core-drive stage.
- Cutoff CV A— Cutoff CV input with its own dedicated attenuverter.
- Resonance CV— Resonance control-voltage input.
- VCA CV— VCA control-voltage input; use it with the OUT VCA switch off.
- Morph and VCA— Dual-colour indicator showing filter morph position and VCA level.
How-To Guides
- Cross-modulate cutoff
- Use the built-in VCA
- Use as a standalone filter
