FFT artefacts from multiband delay tutorial.
Hey, I am having some issues with this patch which I downloaded from a tutorial on FFTs. https://www.youtube.com/watch?v=gIZoyT380KQ .
It sounds fine in the video but when I downloaded and used it in live, I heard this bitcrushy/ring mod like artefact. I am unsure why this is happening. Does anybody have any ideas? I have put the patch below along with screenshots.
