Vortex Sound Research

Hi I was hoping someone could answer a question about Erica synths black eg. The looping function will not work. It says in the manual that it only works when the gate signal is high. What do they mean by high? It’s hooked up to the Erica synths midi to cv converter and I was not aware that the gate signal strength ever changed. It worked when I first got it however as I added modules I suddenly noticed it didn’t work. Everything else on my set up works. Everything else on the module works. The CV sends out two control voltage signals and two gates.
