MXXX: Multiband clipper with user-defined slope like mSpectralDynamics?

[Annabanna]

GOAL:
Create multiband clipper where band ceilings are relative to user defined slope in much the same way that the slope feature is used in mSpectralDynamics. In other words, if the band ceilings are all set to the same value, and I push noise through it hard enough, the output should always be horizontal when viewed at the same slope the unit was set to.

For instance, I can put a waveshaper on every band of a multiband instance of MXX where each band just chops off everything above -12dB (or do the same thing in mWaveShaperMB). That does exactly what I want, but only at the built in slope of the default crossover (3dB/octave?). In other words, if I push noise though hard enough, the output should be "flat" hen viewed at the same (3db/octave?) setting in mAnalyzer.

I'd like to do jut exactly that, but with a slope control like mSpectralDynamics where the ceilings are subject to that slope, so if I set the slope to 4.5dB/octave and push noise through hard enough, the output should be flat (horizontal) when viewed in mAnalyzer at a matching 4.5db/octave setting.

Ideally, I'd like the slope to function more or less like it does in mSpectralDynamics, but for the unit to be a clipper rather than comp/limiter (zero attack/release), and with a relatively small number of specific user defined bands.

Is there some way to achieve this (using mXXX, mWaveShaperMB, or any other tool or combo?)

I quite don't follow - that should be quite easy to do with multiparameters controlling in/out gain of each MWaveShaperMB band.
