Hi
Thank you both for your interest and support.

There are 3 things to consider hence my description.
To hear your keyboard playing the voice or synth set for a track. Be it the default or a plug in

1: Set thru to track specific in options / preferences / midi / midi thru.

2: If you are using a default midi synth in midi setting under the midi device icon
That is tick in the box reroute midi to DXI/ VST if using one.
That is all you need.

3: If you have another midi synth as a plug in on an other track to hear its voice as the thru voice you must take out the tick above. And then insert separate instances of what was your default synth to any tracks that required it.
This is all to do with port allocation and what Realband treats as the thru voice.

There is more about ports in my original post.

Have fun
Mike
