Foxtrot: Quad Multimode, Multi-Topology Filter
Foxtrot is a quad, multimode virtual analog filter with three different classic filter types.
Each of the four filter channels can be:
1) A ladder filter, based on the classic MOOG designs from the '60 and '70s
2) A Sallen-and-Key filter based on the Korg 35 module used in the MS-20
3) A State Variable filter as used in the Oberheim SEM
Each filter type produces Low Pass, Band Pass and High Pass responses which can be morphed between using the front panel control or CV.
In addition, any or all of the filter channels can be linked together internally producing a parallel filter bank controlled by a single cut-off control or CV. Check out some of the examples for how amazing this sounds.
The AUX CV input can be switched to allow CV control of the filter response, resonance or pan of each filter channel's dual outputs.
Finally, each filter can be overdriven to accentuate the unique sound of each filter type.
