Available as an assembled Module and as a DIY project.
This Module is currently available.
Based on the Steiner-Parker Synthacon VCF
Connect the CV input to a voltage source such as a keyboard, envelope generator or sequencer. connect the output to a VCA or amplifier. feed the signal to be filtered into the high-pass, band-pass or low-pass input. if the same signal is used in all inputs, the result is reminiscent of a phaser. the real fun starts when you feed different signals into each input, then you get a frequency based "interpolating scanner", where panning between different sound sources is possible, though also subject to the frequency at which they are running.
Each of the filter type inputs has its own level control. the all input is also affected by these level pots as it mixed with the individual inputs prior to the level controls. if using only a single input, it may be better to feed the signal into the all input, and adjust the level pots to select lp, bp or hp, rather than changing the patch cord between the specific input jacks.

These merchants probably sell this module. Huh?
