Noel, thank you for your reply.

I installed build 8 this morning and gave it a try with a new .seq file. This time I'm using _GRVYPNO - Groovy Piano Pop style and testing the gain nodes on the real tracks only.

I found the BB Real Strings 686 - Organ track doesn't care what level the gain node is set. I have it set to -64 db and still hear the organ unless the channel is muted. I can move the volume slider on the track and hear the change but the gain node has zero effect even when playing the song within Realband.

When I render the song, the gain node seems to work for the piano track and the BB Real Bass track.

This problem really has me stumped.
