I suspect this is easy to do but I’m blanking at the moment. Any help welcomed.
Using the Smoothness FX I can create a slider with a recent value. If I could subtract this slider’s value from the current (and lose the sign) I’d have what I need…
PS I can’t find current numfx documentation on the website.

There’s some info about Number FX in the docs: Data Sending and Receiving | VIDVOX Docs
And a tutorial here: Creating a 'Falling' audio level data-source using number FX chains in VDMX — VDMX - MAC VJ SOFTWARE
I did the math in a Vuo plugin and that seems to work OK. I’m still curious if there’s a way to do it in VDMX native.
