I'm building a semi modular effect. The user can select an effect on every slot, but when an effect is chosen, then in the other effect slot must the effect removed. I'd build some logic, but I have empty places. How can I remove them?
See my schematic

Best Regards

yeh its just a saying Yuroun
a bit like "well thank you very much"
I see what you mean about not working perfectly, it seems the last column does not always update properly, I will have a look at it and see what i can come up with
