Assigning a single parameter (eg filter cutoff) across multiple zones. Simple or script required?

[misohoza]

You can do this without script. It can be done by changing scope.

Edit Scope (steinberg.help)

Assign filter cutoff of one zone. Click into the value field. You should see something like:

@0:Zone 1/@id:140002

Change it to:

@type:Zone/@id:140002
