@CTEPEO3ABP, для твоих причуд по описанию может зайдёт.штатными если не пойдётapQualizr2 can be used for all standard EQ applications and can produce many modulation and dynamics effects thanks to the included dynamics and lfo modules. Filter bands can be controlled with midi keyboards and controllers using the built-in midi module.
apQualizr2 filters are based on a unique method to match ideal frequency response curves over the entire frequency spectrum.
Applicable filter types have adjustable steepness (adjustable number of poles/slopes) and can be individually switched to mid-side processing
Filters have a ++ poles mode where slopes get very steep and the full gain change is covered within one semitone.
Spectral tilt and variable-slope low- and highpass filters allow continuous modulation of their tilt/slope parameters.
