Foxtrot Duo Mk II: Triple mode, stereo VCF

A great VCF is the heart of any rack, and Foxtrot Duo Mk II offers three classic filters in one module.

● A fat, squelchy ladder filter based on the Minimoog.
● A crazy, screaming Sallen & Key filter based on the first edition of the Korg MS-20.
● A velvety and rich state variable filter based on the Oberheim SEM.

Each filter can be swept from Band Pass, through Low Pass to High Pass (with Notch on the way!) plus there’s a 12dB input boost if you want to drive the filters harder.

Foxtrot Duo Mk II is stereo, so has two completely separate filter paths. A new control (and CV) allows you to offset the cutoff frequencies of the two filters, which can generate anything from formant-style sounds in Band Pass, to frequency pans in Low and High Pass, to phase effects with the notch filter.

Plus, there’s a new, dedicated V/Oct input for improved keyboard tracking.
