I built an NLC Delay No More 3 eurorack module. I have no idea whether it is working as it should or if there are issues with it, so here is what it sounds like, for your own opinions.
Yes, it's working correctly. Feedback from other channels all the time. Use the IN1(3) input instead of IN1 to turn off the feedback from channel 3 to channel 1. The switched contact in that jack will be turned off and stop the feedback signal once you put a cable in there.
It‘s not feedback from other channels but just passing on the signal to the next line, could be interrupted by patching the second jack. See module description: The 2nd row of inputs use the jack switches to forward the output of each stage to the input of the next, so if you wish to use the delays individually, use these inputs to break the loop.
