*About (classic) low/high shelving I need this for my patch I have programmed low and high shelving abstractions, using hip~ and lop~, but these are quite complicated (difficult to add or remove some frequencies with the SAME parameter)
this latter problem was solved using this technique : adding +~ 1 to the signal before processing and -~ 1 after processing therefore all the sound processing is done with positive-value signals, so it's easy to add or substract some frequencies to the signal
