multiple inputs on expression editor

[busyframes]

I'd like to send floats from a hardware controller (like a touch screen or midi device) to the expression editor node. I have discrete floats coming in and plugged into different expressions but when I have more than 1 plugged in, the node stops updating until I restart comfy. My input DOES work and the parameter is updated in the preview when I have ONE parameter input connected. I'm guessing the problem is all values are being updated when really I only need the value that's changing to update. is there anyway to do this in comfy or is that just the nature of execution and inputs?
