I also have set in my Realband Options / Preferences / file:

Don’t save forced mid ch meta event in midi file

Automatically re channel track data when saving to midi

Not that I would be saving this type of project as midi anyway as explained above.

Mike, can you please explain the above quote. I am trying to understand why you would do this. I am still having one issue which I thought I was having when I saved my project but I was wrong. The issue I am having is as follows.
1 record oboe track 2 channel 1. Set synth to oboe and channel 1
Records fine
2 record strings on track 3 channel 2. Set synth to strings on channel 2.
As I record strings in track 3 channel 2 the oboe also switches to the strings although it was already recorded as an Oboe in channel 1.
Thanks Rich
