I am having the same problem. I have an Audiofuse Studio, as well. I connected the input of the H90 to the output of the interface and an input from my interface to the output of the H90. I use Ableton Live 11. Nothing happens. What other steps can I do in order for it work? I use TR cables. Is there something I have to do in the H90 and Ableton or both. I would appreciate a step by step procedure. Thanks
