Split CV at threshold

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?

There is a utility module from Xaoc called Samara, the scan mode will switch through three inputs when a fourth signal crosses the threshold (-1 to +1, +1 to +3, +3 above). But it sounds like you want to multiply a signal and invert one copy so your two destinations mirror one another. In which case, look into Invert, Polarizer, Offset modules and if you only need on/off (0% to 100%) see Gate Logic like NOT.

A comparator and a vca (and perhaps a buffered mult) will get you there. ladik makes a great comparator which allows you to set a threshold manually, and sends various gates depending on the relationship of the threshold and input voltages.

In your example, route the cutoff cv thru a vca that will be opened by the 'greater than' gate output of the comparator.
