Hi all! I am new to XOD and I just wanted to share a node that (I hope) will be useful to others. This is a hysteresis node, it filters the input signal, so that the output is more stable for small changes near the threshold values. Sometimes it is called a “Noise gate” and you can find more info here: [Wiki](https://en.wikipedia.org/wiki/Noise_gate) ![svg](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/36ba574f4aef7ceb74bb46d3831fb415c3c5fac0.png) I was quite surprised how natural and easy to understand was XOD implementation of this node. I even added a small example to the library to illustrate a possible application. Feel free to try it out! ![hysteresis](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/7bb21ca5a6a2165f303a0db3eb5bc756fef8929b.jpeg) [Link to the lib](https://xod.io/libs/faberge/hysteresis/) ---

That sounds like a problem with your install; that is a valid node that is distributed with XOD. You might want to try re-installing XOD on your box. ---

I am confused then =\_= This example works well on my computer. And yes, this is a standard node, so it is very strange that the IDE can’t find it. @gweimer, have you also tried this node? ---

Fascinating…I get the same error. If I delete greater & replace it with “the exact same thing”, it then complains about the flip-flop, then the less. After replacing all 3, it complains about the greater node again… If I start from scratch and generate the same node, it works just fine. I’m running XOD 0.19.2 ---
