A discrete VCF full of character
The completely unlinear response and discrete circuitry gives the Journeyman a unique sound of its own. Partially modelled after a classic Japanese filter design from the mid to late 1970s, the Journeyman can be configured in either -6dB/octave high pass or -12dB/octave low pass modes by the flicking of a switch. When two of these VCFs are used together, one in HP and the other in LP, then the effect is superb.
The filter heart is made entirely from a single ended discrete design and uses four matching diodes as the control elements. The filter behaves differently depending on the input signal level hence the 'drive' pot on the front panel. Turning this up allows the filter to be overdriven. At full resonance the filter will oscillate across most of the audio band.
The 1U 'Filter Core' format can be used as a filter module on its own. But users can also employ external mixers to control CV and audio levels going into the filter. In this way, you will be able to have a collection of space saving 1U filter cores that can be used with any generic mixer module. The popular Oakley Multimix is the perfect choice for such a mixer module.
These merchants probably sell this module. Huh?
