Quad overlap in RNBO fft hann window

For anybody that has played around with it using hann windowing in an RNBO fft is quite difficult for a newbie. I have played around with all the available fft patches from cycling using hann windowing and none of them use any more than a dual overlap. If you play a regular audio file through these examples you get noticeable distortion no matter what you set your audio settings vector size to. If you use just a single fft process with hann windowing(and yes the windowing is also declared in my ~ifft) the audio is unintelligible. I have used the given dual overlap fft~ 512 512 0 and fft~512 512 256 and it gets a little better. In the fft docs for RNBO it says you can abstract the process with more overlaps by changing the fft arguments, and yes my ifft~ is set correctly and taking in both outputs both real and imaginary from the fft. I just don’t know what arguments to give these further abstractions

I imagine with an overlap of 4 the audio might get better but being so new to this I don’t know what arguments to give anything I try sounds unintelligible like adding an fft~ 512 512 1289sounds horrible. As I said the dual hann is getting closer but riddled with distortion. Any help would be greatly appreciated.
