G-Storm Electro - JU60-VCF

The G-Storm Electro JU60-VCF emulates the fine filter sound of the Roland legend Juno 60.

And once again G-Storm Electro indulge in their favorite hobbyhorse, the Roland filters. This time it's the turn of the filter from the legendary Juno 60 synthesizer, which has become an ultra sought-after vintage behemoth and finds itself in the center of attention more often than e.g. its sibling synth Juno 106 because of its fat sound. The filter is based on a four-pole OTA design, which Roland started to use in the "Dino" System 700 in the seventies and used in modified form until the eighties. For the Juno 60 filter, the circuitry was implemented using an IR3109 (four BA662 in one IC package). The filter circuits of the Roland classics Jupiter 6 and 8, JX3P and SH 101 are constructed in the same or similar way.
G-Storm Electro has also reverted to this vintage design for the JU60-VCF, extending the functionality even further compared to the original. As with the Jupiter 8 filter, the sonically identical VCF is switchable from 4-pole to 2-pole operation, which was not possible with the Juno 6/60. The sound, however, is as expected Roland-warm and fat, the resonance is capable of self-oscillation and produces an official sine wave on its own (Dub Bass, anyone?). The two inputs with their own mixpoti can be used to feed in two separately volume controllable audio signals, the CV-Ins 1 and 2 allow modulating the cutoff frequency by means of a polar/bi-polar modulation source. The output jack (Larry Heard anyone?) will blast your electronic filter dreams out into the wide world.

Features:

• Filter module based on the lowpass filter from the Roland Juno 60.
• Vintage-IR3109 circuit like the original one
• Switchable from 4-pole to 2-pole operation (like in the Roland Jupiter 8)
• Resonance capable of self-oscillation
• CV 1/2 for modulation of cutoff frequency
• 2 inputs with dedicated mixpotis
