Hi, Chickinox:


Are there other staves in your file other than the one you're trying to play into?


If they are physically below your staff and set to the same Midi channel, they would then override the higher staff and send their patch info when you start to play. That would result in you not being able to change the voice patch.


The solution is to make sure your staves are set to different Midi channels.


Hope that helps.
