| br>Dangerous territory posting this whilst the first module isn't shipping yet and I further develop a reputation for tardiness, but here's a tease for my next module. This one pretty much made itself. Based on a THAT application note (DN130) for a state variable filter. With advice generously given by Rob Hordijk on equal power panning curves.
Most of the process was about tweaking the functionality, e.g. there is no linear mode, no VCA mode. But for me low distortion, low offset and 4 independent channels are the priority. There are a couple of clever bits such as differential drive of the THAT2180 for minimum CV feedthrough, but for the most part it's a module based on functionality only, and very little glamour, but nonetheless a necessary one!
