Hi,
I was considering the purchase of Faderport8 but this post is scaring me. …
Are you running Windows or Mac? Did you try on Cubase 10.0.60? Did you contact Cubase support?
Does this happen on Windows 10 if a separate USB port is dedicated to the Faderport?
I recently bought an Icon Platform M+ interface and I returned it because of this same problem that you are describing (continuously disappearing from midi devices). The Icon Platform M+ had many other bugs so I won’t go back but I would like to know if it is safe to use Faderport.
Thanks!
