I like it a lot, and have used it a lot. Itās fairly indispensable for me.
That said, when it comes to NLC filters, I probably reach for either the Feague or Serious Filter first. The FK1T tends to fit in in a more specialized role; not quite as general purpose. It may be slightly more limited, and I find that itās a bit finicky as to getting it dialed just right. Itās inspired by a particular Korg filter if I remember correctly, one that is a bit peculiar. The dual inputs are very cool to have, but thatās a strength across almost the entire line of modules: multiple ins, multiple outs. Feedback heaven.
