Conjured Circuits JP6 Multimode VCF

"A sweep through the octaves and modes. Analog spring reverb used from Synthesizers.com"



"Sorry for line noise."

Note 2U refers to the width. This appears to be a 5U or MU module.

"Jupiter-6 Inspired Multimode Filter

The Roland Jupiter-6 is a 1980s analog polysynth with a great sounding multimode filter that is quite distinct from other Roland filters of the same era. Here it is recreated in a 2U Moog Unit module with an added 2-pole 12dB low pass mode, reminiscent of the Jupiter-8. As with most vintage Roland filters, it is based around a cascaded Operational Transconductance Amplifier (OTA), in this case using the LM13700 OTA in place of the obsolete Roland IR3109 quad OTA.

4 modes: 24 dB low pass, 12 dB low pass, band pass and high pass
2 audio inputs, logarithmic attenuated
2 frequency CV inputs, one unipolar input and one attenuverted input
1 resonance CV input, attenuated

Pittsburgh Primary Oscillator With Cloak & Dagger Filter

Published on Jul 9, 2018 Perfect Circuit Audio

"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.

"CONJURED CIRCUITS CLOAK & DAGGER

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
Mode LED indicates selected drive settings"
