Hard to explain, but I'm looking for a module that can take an incoming CV signal and split it at a threshold, essentially making it two CV signals where the second doesn't send anything until the threshold is met. For instance lets say i have a single source and want to control two values, like decay time and filter cutoff, so when the input CV hits 50% it has opened the decay to 100% with the cutoff still at 0% and at 100% it has the decay at 100% and the cutoff at 100%.

Does such a thing exist?
