“Filters aren’t magic, it’s just mathematics. It’s an finite amount of figures, and even more so, a finite amount of frequencies. That’s why you will always face a certain problem when modelling analog filters, or filters in general: certain parameters will interact. With virtual synthesizers you calculate that away with a lot of effort. But you can’t get rid of it 100 percent.” (Jürgen Michaelis) — Jomox Tech Talk feature, taken from Slices DVD Issue 4-09.
