Softube Intellijel Rubicon v2.5.9

FULL INFO BELOW:

The Rubicon, from Canadian Eurorack wizards Intellijel, is an analog triangle core VCO, capable of thru-zero frequency modulation. Originally created by Dave Dixon, it is rightly considered an analog VCO design masterpiece.

Now offered as an officially licensed expansion for Softube Modular, the Rubicon is ideal for experimenting with FM synthesis ? broadly speaking, the modulation of one audible waveform with another ? and can create very complex and detailed sounds, both harmonic and inharmonic.
