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

These merchants probably sell this module. Huh?
