hi @baxgas, thanks for the suggestion, i tried the regular version, but no luck..
so i changed my testing procedure, to be closer from real use case, and, yes, sadly, the cpu started to overflow very quickly. so, some radical optimisations needed

i removed oversampling on lot of filters ; in a mix you won't hear the change i guess

+ removed lot of waveshaping, well, the good news is that it sound cleaner now

(or cheaper

now it seems to work well with a 4 track sequencing. it still may overflow if you really insist, so i will try to free more cpu cycle if i can..
i may remove lp2 & hp2 as these are still oversampled, and now lp & lp3 seems to be enough.
