Thinking about digital filter implementations on synths like the Waldorf Blofeld and Access Virus synths. Particularly implementing drive and non-linearities. A bit of DSP archeology if you like.
Given the age of those synths I’m guessing that modern(ish) techniques of solving non-linearities to closely emulate analog filters, i.e. Newton–Raphson, weren’t used. They perhaps weren’t even zero delay either?
In particular the Blofeld has a number of different filter drive types. Given the limi…
