Sorry Nick. It’s my first time posting on this forum, and I just asked two different persons hoping someone would answer and I am glad you are so prompt in helping.
I disabled the Midi routing on the H9 for Input and Output. I will keep you posted if the problem reoccurs.
Thanks for your help!
You have the same issue on another thread – this kind of wastes time.
Further, I have to say I know nothing about the Helix.
My suggestion is that you look at the H9 and disable MIDI control of ISW and OSW.
