My post on Flowstone Guru is no longer accessible, so I repst it here.

The TDF2 filter topology has the advantage of using only 2 states hence CPU load is low. The main drawbacks are (i) truncation errors at low frequencies and (ii) instability against fast modulation. The ZDF topology solves both issues at little extra CPU load.
