@d-healey Ok got it, Thanks. ;)
So with this way, "Mono Filter is allways on top in master fx rack" limitation can be solved.
Because there are a couple of filters in this core modules.
Since ScriptFX can be used everywhere; so the developer don't have to be stuck on Mono Filter that is allways first on the fx chain :) Maybe this way would not be flexible and fastly useble like Mono Filter but it should work in most cases.
