Foxtrot Duo Mk II Dual Multimode Filter

Blaknblu Foxtrot Duo Mk II

Foxtrot Duo Mk II is a stereo multimode virtual analog filter from Blaknblu, now with an updated interface and improved DACs. Bring three classic filter topologies to your Eurorack rig in stereophonic style: choose between the rich and resonant Moog ladder filter, the screaming chaos of the Korg MS-20, or the gentle sweep of an Oberheim SEM. Hear these modes cleanly or engage the boost switch to hear more dramatic response from each mode.

Each filter type can be smoothly swept through band pass, low pass, and high pass filter outputs using panel control. In addition to two independent CV inputs for cutoff, Foxtrot Duo also includes an Aux CV input that can control filter type mix, resonance, or panning in mono mode and stereo tilt effects in stereo mode. A highly flexible and great sounding filter, Foxtrot Duo Mk II from Blaknblu is here to become your closest partner in stereo spectral shaping.
