I remember back in the day when I was messing with Volcas and Pocket Operators / synthesizers, I tried a #eurorack simulator called VCV https://vcvrack.com/

They're open source!

https://github.com/VCVRack

Maybe I'll download and play with it for a while one of these weekends... I don't know if I still remember how to work it.
