I have this problem for both NinJam and ReaNinJam in Reaper.
I've been trying to add a third channel and it doesn't persist once I connect to a server. The channel works up until that point but as soon as I connect to a server the channel is non-functional (no sound coming from it).
Is there a limit of 2 channels?
Thanks everyone!
Here are some screen shots:
1) The third channel is working because I am not connected to a server:
