That's kind of the whole deal about (analog) triggers, I guess. The triggers can vary in length and voltage.

My Befaco Modules send pretty strong (10V?) and short pulses. The LL8 is some what slow and I think it's outputting less voltage.

I'm currently shortening some of the LL8 Triggers with Stages but also thought of getting something like this ADDAC217 to free Stages. https://www.modulargrid.net/e/addac-system-addac217
