Well Im pleased and slightly bewildered to say that i could not recreate the problem with the fx chains tonight. I started with the same stereo source through to four sets of different dante channels then put different sources through each channel then finally reloaded my cubase project with the send/returns setup and everything just worked. Effected audio in out and back with bouncing levels on all four fx chains simultaneously.

I also got excited when even tricerachorus worked, for maybe a minute, until it descended into the digital buzz of last night. So maybe it just doesnt like running at 96k for now. All other effects remain fine.

Should i ever be able to recreate that fx chains issue i will make sure to forward the session along but yes tricerachorus still doesnt seem to be happy at 96k for me.
