How do I stop BSP from passing notes thru?

[JavaLaurence]

When there's no sequencing happening, I have one of my keyboards triggering notes on another (when I play the first). It looks as if the BSP is receiving the notes from the first keyboard and sending it to the other. Is there a way to stop this behaviour?

Nobody else who has seen this behaviour? Anyone?

I wouldn't call it a problem as such, I find the problem is it only passes some channels, not all.  Though I can't find how to turn off thru and that is what you are asking to know.  Sorry.
You could change the MIDI channels of the instruments you don't want to trigger at the same time so that they are not the same.
