Conjured Circuits has produced the Cloak & Dagger, a completely analog filter / distortion module based on the ARP 4072 "post-lawsuit" filter. With resonance compensation, switchable drive pre and post filter, and attenuverters for both CV inputs, the Cloak & Dagger is an incredible way to add several flavors of 2600-style sound to any Euro rig.
Cloak & Dagger Features
4-pole lowpass filter based on the ARP 2600 4092 submodule, the "post-lawsuit" filter
Switchable drive for input and output with dedicated level control and CV input with attenuator
Two CV inputs for cutoff frequency with dedicated attenuverters
Self-oscillates at ~80% resonance
Built-in "resonance compensation" ensures low frequency levels remain consistent as resonance is increased
Dedicated 1V/oct input for musical filter tracking
Pittsburgh Primary Oscillator With Cloak & Dagger Filter
For this video we made a synth voice with the Pittsburgh Modular Primary Oscillator and the Conjured Circuits Cloak & Dagger as VCF and VCA. We used the "timbre" output of the Primary Oscillator which is either a sine or triangle wave run through a wavefolder. The Cloak & Dagger is an ARP 2600 style VCF with overdrive before and after the filter. Everything is sequenced by the Eloquencer, the LDB2 and expander create the drums, Rampage is an envelope and LFO, and everything is mixed with an Intellijel Quad VCA.
