A very good discovery! I had been selecting "master keyboard" as the midi controller and things just did not seem to work ok. Today I selected "digital piano" and everything has come together - even the style volume issues have been resolved.

So, if anyone is using the Roland A-800Pro controller with the BK7m try selecting the "digital piano" choice. Now when I turn on the OTS and select one of them it also changes the variation and the split stays on. Just what I was after.

I knew there had to be something I was not doing - but in the manual it recommends using the "master keyboard" so that what I tried.

More as I learn more.
