Hi Terry,
Did you try using the same song in Notation Player and Notation Musician? Did Player give you one result and Musician a different result? I would find that odd, but if it's true, it's a bug that we would want to figure out. If that's the case, would you mind please letting me know (1) the difference you see/hear (and where it happens) and (2) send me a copy of the file either here or at
support@notation.com
If it is the particular file that is causing the stop changes (ie. it happens in both Player and Musician), then I suspect that there may be other MIDI controllers (aka MIDI cc events) in the file that are acting on the organ. Notation Composer does allow you to edit these types of events, and may be useful in these cases (Musician does not have MIDI event editing capability.) You can try it out free for 30 days to see if it lets you edit what you need to in order to remove the MIDI controller(s) that are causing the stops to go out.
ttfn,
Sherry
