I try to use oversampled hard clip with oversampling kit..
x2 much clearer but no difference between x2 and x4. what im did wrong?

Use the Up/Downsampling modules from the "Oversampling Kit (MyCo)" Module. This kit has many fixes and optimizations that the original kit didn't have.

Don't know the exact name. But it's just oversampling using half band filters. It doubles the sample rate removes the aliasing using a half band filter then it goes into your effect and finally it uses the half band filter to limit the frequencies to 1/2 of niquist frequency and outputs every second sample interpolated.

It just looks a bit stupid in FS, because we can't process samples in higher samplerates. So we process even and odd samples of the higher samplerate stream in 2 separate streams (running at original sample rate in parallel)
