Thanks! The filter is a completely different design compared to Lohi or Tiltshift so it's not going to behave the same — it took a lot of listening tests and modeling to get right, but I think you'll like it

Tupe's filter does already have independent frequency, slope, and resonance controls (which are easy to access). I think it'll probably make more sense once you try out the beta!
We've been using it A LOT for guitar and bass DI. It's perfect for it especially with zero latency.
