Band Split Delay plugin which will hopefully be released to the public one day. The aim of this plugin is to offer 3 bands each with their own reverb and delay settings. The inspiration for this came from FL Studio's Patcher, in which I've made this exact thing and it sounds awesome when paired with the right instruments.
Why do you think that https://github.com/calebzulawski/fourier is a good alternative to Band-Split-Delay
