Thanks for all the replies. I have yet to use an outside library like RNBO or Faust but maybe its time I give something a shot.

I figured out a way to get a detune effect (sort of) by modulating the Delay of a Simple Gain effect. Not perfect but for small, subtle changes is ok.

I will check out these libraries and try to dive a bit deeper into one of them.

Beast and thank you.
