From Modulargrid:

We looked very closely at how some of the most loved timbre shaping circuits worked in classic synth modules; Not just in how they were implemented electronically but how they sounded and how efficient they were to get great sounds. it was important that their design was very versatile in range of timbres but still easy to use and with well thought out control ranges.
