First Combinator turns itself off when pressing play

[marklumsley]

I'm using Reaper ReWired with Reason 8.3.2.
This problem has never happened before in my MANY years of using these two programs together.
Whether I'm in Reaper or Reason, pressing play in either (space bar or the button onscreen), it will turn off the first Combinator that I'm using.
Whilst playing, I can manually turn it back on, but of course this is very undesirable as this hasn't happened before and is EXTREMELY... annoying.

If anyone has experienced this problem before and has any idea of how to fix this, I would really appreciate the help.

Thank you.

By the way, I'm new here (if it wasn't obvious), so please advise on where else I could seek help if not here.

That’s definitely an odd issue. My first thought is perhaps you may have accidentally automated the combinator switch.

Very unexpected indeed.

Can you clarify what you mean by "first" combinator? Like first in the sequencer or first at the top of the Rack?

I can only imagine some sneaky automation is there without you knowing.

Or perhaps a midi controller is sending a particular CC on playback.
