Well, to be fair, the module has been around for many years. It was 
probably second only to Doepfer in the small format modulars.

It does have a very unusual way of clipping the feedback. IIRC it has a 
single zener diode around one of the op-amps creating a very asymmetric 
output waveform. Not really my cup of tea but a lot of folk like it.

Actually, that's not so common amongst OTA based designs. Most of them 
use a PNP pair rather than an NPN pair with a mirror.

Indeed.
