It is mentioned on the A-190-3 info page:

www.doepfer.com > English > PRODUCTS > A-100 > Module Overview > A-190-3

The info page says: "In the A-190-2 the LED shows the gate function (i.e.
LED = on while gate = high / LED = off while gate = low). In the A-190-3 the
LED is permanently on and turns off only for a short time when an incoming
Midi message is recognized."
