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

Available 3/2020
