...for some reason, I cannot turn "Param Rcv" on CC in my OB-6 Keyboard version...
Hello,
first comment on the forum, I registered because of this exact same issue. As I can see, it was never answered.
Before posting I solved it, so I will share how I did.
In my case using Ableton Live 12 on Windows 10, I switched off all the other synths to be sure that nothing was interfering with the problem of not being able to select NR in the PARAM XMIT / GLOBALS.
The problem persisted until I switched off the Roli Seablocks that I use as a MIDI controller.
Seems the Roli is sending clock outside, I will have to check why and how to change it, I don't know, but now the NR in the PARAM XMIT of the OB-6 is working and available.
