You can manipulate your sound in so many ways with this app and create lots of movement and sonic overtones. Love this filter, it’s worth every penny! ### 5/5 — Aggressive, characterful filter! *2023-11-03, version 2.5.0* If you need a screaming, aggressive filter with plenty of modulation options, this is what you need! Give your tracks some Soviet Union era flavour and grime!! ### 5/5 — Awesome ok *2022-11-07* Do yourself a favor and get some of the devs apps well priced and killer sound. Don’t mind the bloke who is getting butt hurt about the name just to tarnish a good dev and app! ### 5/5 — Potente ed efficace *2022-10-19, version 2.0.0* Ottieni subito risultati significativi in modo semplice.
