Audio into Murf Step?

If I split the signal coming from my bass & put one signal as normal through my FX chain & took the other signal & put it into the tap/step on the Bass Murf & used a step adaptor, would the signal control the step (can boost it if needed)?

It should work, but you’ll probably need to boost it.

I split the signal using the direct out from a Boss OC3 & hooking it to the step adaptor - Nowt.
I tried boosting it - Still nowt.

Clicky pedal back into adaptor it is then.
