Here we have a new Eurorack DIY stereo filter from Thonk Synth. It’s a stereo analogue multi mode filter made for creative modulation. Whether it’s dual parallel channels, series filer routings, mono to stereo, stereo in and out or even mono filtering with a separate filter modulator (a filter modulator? What? – heads up, it’s ace!). Check out the patches below.
